The LORENZ DEEPMAX X5 and X6 seies detectors are
some of the newest developments in the field of Pulse
GBS metal detectors. It is probably one of the most
sensitive and stable metal detecting devices of its kind
presently available. The LORENZ DEEPMAX X5/6 is the
result of many years of research and development. A
lot of efforts have been put into making this new product
and especially in the new improved metal classifications
and automatic ground balancing facilities offered with
the LORENZ DEEPMAX X5 and X6 series.
The Pulse GBS (Pulse Ground Balancing System) is
specialy suitable for searching at depth. The performance
of this electronic device is almost unaffected by salt
water, most types of mineralised grounds or temperature
changes. Specially designed electronics cancel out signals
from the ground. The LORENZ DEEPMAX X5/X6 is
therefore a reliable tool to locate metal objects at great
depths even under the worst environmental conditions.
A new improved circuit design suppresses interference
from power lines and a power pulse technique produces
very accurate signals to obtain very high detection depths.
The LORENZ DEEPMAX X5/X6 is a high quality specialist
Detector and it is designed to be used with both, small
or large coils. Large coils offer extreme depth capabilities
for big metal objects because of the strong and deep
going magnetic field produced. Small coils are preferably
used while searching for small objects like single coins
or gold nuggets.
This model offers a great range on non-ferrous metal
objects in general. A very simple operation is guaranteed
by a specially developed LC Display and a minimum
amount of controls. At the same time this detector model
offers a number of features which are new for a pulse
metal detector. Quality electronics and very special
designed electronic - circuitry produce benefits in terms
of easy of use as well as sensitivity.
The LORENZ DEEPMAX X5/X6 gives a visual indication
on the LC Display for every metal being located. This
time delay reading producing a number between 000
and 099 helps to classify metal objects. The target
classification circuitry is only in some cases affected by
the size of a metal object and therefore identifies small
coins as well as large pieces of metal. The LORENZ
DEEPMAX X5/X6 also offers a sophisticated and refined
ferrous / non- ferrous target analysis which works more
stable on difficult soils in conjunction with the 26cm or
35cm double D search coil. The Detector also emits an
audible sound by way of either a speaker or headphones.
Detection depths achieved (in air tests) are almost the
same in many types of soils and therefore considerably
higher than those possible with standard pulse induction
or sinewave VLF - TR Detectors.
The DEEPMAX metal detectors are often recognised as
representing some of the highest quality and newest
developments in professional metal detecting equipment.
We as a manufacturing company always try to keep the
highest standard on our products, therefore alternations
of the design, specifications as well as the availability
subject to change without notice.
1. Safety information
For reasons of safety it is advisable to read this
operating manual first before turning the Lorenz
DEEPMAX X5/X6 on. Special attention should be paid
to the following notes.
Check out, if the plug-in type charger supplied with
the LORENZ DEEPMAX X5/X6 fits with the AC mains
of your country. The AC plug of the recharger is interchangeable and therefore can be used at any countries
mains. See chapter 7 for more detailed information.
The supplied recharger will work at AC voltages of
100-240 V AC (see label).
Damaged connecting cables or search coils should
no longer be used, because of possible electrical
shock.
To avoid short circuits, wrong polarity or electrical
shock only spare parts and accessories offered by the
manufacturer of the LORENZ DEEPMAX X5/X6 should
be used.
When digging for metal objects war material could
also be found. Precautions should be taken in advance
especially when big objects have been located.
Special kinds of mines could be triggered by the
strong DC magnetic field produced by the search
coil. Special versions for military use are also available
on request. Persons with implanted pacemaker or
other sensitive device should not approach to the
field of the search coil. Please understand that we as
the manufacturer of the LORENZ DEEPMAX X5/X6
can not be made liable for any kind of damage caused
by or in conjunction with our products.

The LORENZ DEEPMAX X5/X6 is based on the nonmotion; Pulse GBS (Pulse Ground Balancing System).
Short and intensive magnetic pulses are emitted by
means of a search coil first. Those magnetic pulses
produce eddy currents in conducting materials like metal
objects for example. Said eddy currents will be kept in
a metal object and will die away after the magnetic pulse
emitted by the search coil has turned off. This is the
reason why it is possible to detect those eddy currents
during the time delayed receiving phase by means of
the same search coil which now acts as a receiving coil.
A rather complicated electronic circuitry is necessary to
detect those tiny voltage changes and has to separate
that particular signal from interference also received.
The signal has to be amplified to drive a voltage controlled
oscillator (VCO), which emits an audible signal either
by headphones or built-in loudspeaker when a metal is
in the near of the field of the search coil.
Eddy currents produced in a metal object by means of
a pulsed primary field, will die away differently depending
on the conductivity of the metal object. The classification
circuit therefore gives a visual time delay reading for the
eddy currents received over a certain period of time. In
addition a ferrous / non- ferrous indication for every
metal being detected is working when a double D coil
is in use. This gives further information on the probable
kind of metal being located as well as the audio sound
emitted, which makes it easy to predetermine the exact
place and the size of the buried metal object.
2.1. Advantages
The Pulse GBS principle has got the advantage of
using large diameter coils and high transmitting power.
This is especially necessary when searching at depth.
Frame mounted cable coils of different size and shape
can be connected to the LORENZ DEEPMAX X5/X6
without any adjustments.
A special adaptation circuit has been added to the
Detector to suit with different coil systems
automatically. This ensures extreme depth capabilities
with any coil connected. When enlarging the search
coil diameter the sensitivity to bigger objects will also
rise. At the same time smaller objects will be located
less sensitive. This is particularly desirable when
locating large objects while ignoring small bits. Large
coils offer very high detection ranges. Even in difficult
soils where magnetic iron oxides are present the
LORENZ DEEPMAX X5/X6 will offer extreme depth capabilities
for both ferrous and non-ferrous metal objects when the
Ground Balancing System is in use. Other systems often
suffer from ground effects which reduce the depth range
in the ground. The LORENZ DEEPMAX X5/X6 will be able
to locate objects at almost the same depths either in most
types of ground or ”in air tests”. The high sensitivity of the
LORENZ DEEPMAX X5/X6 to non- ferrous metal objects
like gold, silver and copper together with the new target
analysis make this detector an outstanding device for many
different locating purposes.
The LORENZ DEEPMAX X5/X6 was developed to provide
a number of features including high sensitivity and stability
together with easy operation. The amount of controls was
therefore reduced and a calibration of the Detector to our
factory settings was also made to guarantee best results in
the field:

2.2. Applications
The LORENZ DEEPMAX X5/X6 was developed for
professional search and locating applications.
A variety of search coils can be connected to this
metal detector. Large areas can be detected
effectively especially with frame coils. Saltwater,
most types of ground or temperature changes will
only slightly affect the detection range of the
LORENZ DEEPMAX X5/X6. It is possible to eliminate
some unwanted objects like nails and foils or to
identify them as being small unwanted objects
while searching for bigger and deeper objects. In
conjunction with small coils the LORENZ DEEPMAX
X5/X6 is a great tool when searching for small
objects deep in the ground.

The front panel controls of the two detectors X5 and X6
are the same, namely three push buttons with ZERO,
GB Ground Balance, and POWER function and two
incremental encoders with push button for MENU and
SELECT. The X6 offers an additional data logger function
which can also be set by means of ZERO and GB
controls when the data logger function is turned on.
POWER button turns on and off the unit. A connected
and fully charged battery pack and a search coil will be
essential while doing this. The electronics runs through
a tuning and self checking sequence with all the icons
coming on first.
ZERO button retunes the electronics within half a
second.
The ZERO button is the most important control as the
whole electronics, including the discriminator and the
audio will be retuned when pressing this control.
When turning the detector on with the POWER button,
the electronics will automatically retune itself.
This ZERO button has to be pressed frequently to
retune the electronics to the set audio and visual
indications. When doing this simply raise the coil to
the air, far away from any metal objects and the detector
itself and press this button shortly. An ARROW and
COIL icon will come on the display. Rather keep the
coil horizontally to minimize the effects of interference
induction in the coil. There should be almost no signal
indication on the intensity bar graph after having done
this. The small arrow shows the starting point of the
bar graph. Afterwards you can lower the coil to the
ground again. Please be aware that the detector consists
of quite a few metal parts and therefore can indicate
itself. When the data logger function of the X6 is selected
this button also acts as a start and stop button when
taking field data with each track.
GB Ground Balance button will activate an automatic
two step tuning process of the detector to the present
ground conditions:
1. Before starting this process hold the coil horizontally
in the air away from any metal.
2. Press the GB button and don’t move the coil while
looking on the display and watching an Arrow
pointing up with a COIL icon coming on and several
high beep sounds indicating that the first tuning
process is active.
3. Afterwards the arrow is pointing downwards,
indicating that the coil should be lowered to the
soil without any movements at a place with no
metal around.
4. Simply push the same GB button again to activate
the second tuning process while holding the coil
close to the ground and listen for low frequency
beep sounds. The arrow will disappear when this
tuning process is completed. Afterwards there should
be no or only weak signals from the ground when
moving the coil up and downwards when a
GROUND 1,2,3… setting is selected.
During operation the ground setting of the detector
can also be altered by the way of the G1 and G2
control manually.
In general an automatic tuning process with GB
control should be taken first.
When the data logger is active (only X6- version) this
GB button also acts as a field data storing or track
deleting control.

MENU G1 / SELECT G2 Incremental encoders act
as rotary switches to select different functions and settings
of the detector:
1. To open a menu press the MENU control for one
second until a function icon starts to flash on the
display.
2. Rotate the same control to choose the operation
mode you want to change. The active icon keeps
flashing.
3. Rotate the SELECT control until the desired number
is selected and alter the parameter, for example a
low number stands for a low setting, high numbers
will result in a higher setting.
4. Press any of the Incremental encoders or the ZERO
button shortly to leave the menu and go on searching
afterwards.
During operation, when the menu is not active, the same
controls will adjust the settings of the Ground Balance
circuit, namely GND 1 and GND 2 which will also be
displayed with a number 000-999 and corresponding
G1 / G2 icon.
Note: It is necessary to Ground Balance the unit
automatically with the GB button first before starting
to alter ground balance parameters or using a target
identification.
Display
The Deepmax X5/X6 offers a huge number of functions
which are shown on a large LC Display all the time even
while searching. To select a function or alter parameters
refer to the MENU / SELECT controls. The lower part of
the Display shows the different functions and parameters
as the upper part indicates more information on the
probable kind of metal, signal intensity, ground balance
settings, indications for the proper use of the automatic
ground balance or the data logger function as well as
battery condition.
Functions/ Parameters
DEL Delay settings 1-4 offer different sensitivity range
on different metals without excluding ground effects. 1
gives the highest sensitivity range on small and thin non ferrous metal objects as 4 offers a poor sensitivity range
on these small bits and pieces but still a good range on
larger metal objects. The Delay function is mainly in use
while searching with large frame coils on soils with low
iron oxide content. In most cases the coil has to be kept
at a certain distance and at constant height over the
ground to avoid false signals from the ground.
GND compensates heavily mineralised soils containing
plenty of magnetic iron oxides.
Single hot stones or certain iron objects can also be
completely eliminated/ canceled by the way of this
function. Ground settings 1-3 and 4 (only with DD-
coils) will activate different ground canceling settings to
ignore the ground. The ground settings work differently
with the different coils (small, frame, DD). Therefore
please refer to the following table to select the right
setting for your detection purpose.
SENS Sensitivity range from 1 lowest sensitivity to 5
highest sensitivity setting
FREQ With this function the preset operation frequency
of the LORENZ DEEPMAX X5/X6 can be altered. This is
mainly necessary when searching near power lines,
which cause low frequency interference. The performance
of the detector won’t be affected by changing the position
of this control, but the amount of interference can be
greatly reduced by doing this.
Frequency range from 1 lowest to 9 highest operating
frequency. In general this setting does not affect the
electronics and therefore can be left in any position. To
reduce interferences please also refer to our double
frame coil kits to make operation in urban areas possible.
FILTER range from 0 filter off to 5 highest filter setting
to reduce intermittent or pulsed false signals from
inducing power lines or radio transmitters. The response
speed is reduced with higher filter settings, therefore
higher settings are only usefull with large frame coils.
VOLUME 0 turns off the built-in Loudspeaker or
external Headphones 9 highest setting is very loud.
AUDIO With this audio function the tick-rate of the
audio can be selected. The initial tick-rate can be altered
from silent to a low frequency ticking tone. When put
to the 0 setting the built- in loudspeaker will give one
tick every 1- 2 seconds, after the detector has been
retuned with the ZERO button.
The threshold ranges from -9 silent, 0 slow ticking sound
to +9 fast ticking sound. This setting can always be
recalled by pressing ZERO. For most applications a
setting between 0 and +2 is perfect.

AUTO self adjusting threshold cancels out the effects of
drift which could occur during the first minutes of operation
and when temperature changes are present such as sunlight
warming up the coil and therefore alters the electrical
properties. In most cases the detector will work in position
0 as a non motion metal detector perfectly. However in
some cases especially when selecting GND 2 with a DD
coil a low AUTO setting will make the unit work more
stable. Therefore the ZERO button has no longer to be
pressed so frequently. The range starts with 1 very slow self
adjusting to 5 very fast automatic self adjusting Motion
detector. A slow moving speed of the searchcoil over the
ground or target has to be provided to find metals. While
resting over the object the audio and meter indication
disappears. Rather turn off 0 the AUTO function while
using a frame coil in order not to lose too much sensitivity.
DLOG (this function is only available with DEEPMAX X6)
0= turned off, 1= turns on the built-in data logger function
and starts a different display setting with preset functions.
Therefore only FREQ, VOLUME, DLOG and LIGHT can
be adjusted. In addition M Meter length of a track in meters,
TR Track number, FI Field number, HDG Heading for each
track will be available for selection with the MENU/ SELECT
controls as shown before.
1. To start collecting field data first connect the GPS module
with USB stick and the Detector itself. The USB module has
to be mounted on the shoulder of the operator with the
transparent part pointing up. Connect a search coil (frame
coil) and battery pack, turn on the unit and make sure that
the data logger DLOG is turned off DLOG 0.
2. Hold the frame coil in the air, far away from any metal.
Push the GB Ground button once and wait until the high
beep sounds are completed. Lower the frame coil to the
ground at a distance of approximately 10 cm over the ground
and press the same GB button a second time and wait
until the lower beep sounds indicate that the tuning process
is in progress and completed.
3. Press the MENU control for approximately 1 second to
start the menu. Select DLOG 1, M for meter indications,
FREQ (any position that looks silent on the bar graph)
VOLUME (adjust to desired setting) and leave the menu
by pressing MENU/ SELECT or ZERO.
4. Check the icons for the field, antenna and USB coming
on. Flashing antenna means no valid GPS data available.
Flashing USB means problem occurred with storing data.
5. Start collecting field data in the left corner of the new
field by pressing the ZERO button and immediately start
walking a straight line at constant speed. The large arrow
starts to move to indicate that data acquisition is working.
A pulsed beep sound indicates the same. As the M Meter
indication is selected the multi function display shows the
lenght of the track in meters already being covered. In that
case walk a few meters on each track until a useful indication
can be read on the display.
6. Stop the first Track by pressing the ZERO button again.
A low and high beep sound states that the first track is
completed.
7. Move to the next track for example 1m to the side and
180 degrees pointing backwards. Start and stop with the
next track the same way as the previous track, pressing the
ZERO button. A +/-180 degrees indication comes on to
make sure that you move backwards. The multi function
display counts the meters you walk back until you reach
the starting X line with 0 meters again.
8. A compass indication in the middle of the display points
to the direction you have to walk. For example two square
icons pointing to the right show that you are presently not
walking in a straight and parallel line and that you have to
move slightly to the right while walking until the square
icons disappear. In addition the present Heading can be
indicated on the multi function display when HDG is
selected. Therefore simply make sure that the same Number
appears when you walk on each track. A few meters have
to be covered until an indication is possible.
9. At the end of the field push the GB/ field button once
and a longer lower beep sound states that the first field is
completed and stored on the USB stick. The next field will
automatically come on with a higher number when you
start collecting data again.
10.Disconnect the USB Stick from the GPS module and
read the data with your computer with installed Scripter
and Surfer software.
In order to change from M Meter to TR Track, FI Field,
HDG Heading indication simply alter the SELECT rotary
control. This can be performed even during the operation
of the Deepmax X6. When starting with the first track there
will be no HDG Heading available as this track is for reference
purposes only.
LIGHT adjusts the backlight from 0 off to 9 bright
TONE function changes from Analog A signal to Logarithmic
L signal range providing a different dynamic range of the audio
and intensity bar graph in the middle of the display. In the
Analog mode the audio frequency raises quickly to its highest
tone. In the Logarithmic mode the tone will raise quickly in the
beginning and than gradually to the highest tone even if the
metal object is close to the coil for better pinpointing.
Target Identification
The Deepmax X5/ X6 series detectors offer two different
target identifications namely a FE Ferrous/ NON-FE
Non-Ferrous indication which is only working when a DD
coil is connected and a time delay reading of the eddy
currents produced in conducting materials like metals
which works with any coil connected. Both indications
give a hint on the probable kind of metal being detected.
Please find a table of different metals and there
corresponding numbers being taken. The FE/ NON-FE
indication is based on a motion circuit, therefore

000-099 TIME DELAY reading
A time delay reading which is mainly derived from the
conductivity, permeability and the object’s size is displayed
with a specific number on the LC Display. Possible
examples:
(000-020 coin or piece of foil, 030-060 iron, 060-099
large copper or silver object)
The indication is displayed as long as the coil is over the
target.
Any metal object detected will give a specific number
(000 to 099). Therefore a certain intensity of the target
signal is necessary for a time delay reading. The number
simply appears when a reading was possible. The
indication will be stored as long as the search coil is over
the target and turns off when the search coil passes the
target.
FERROUS / NON-FERROUS icons
This function does only work with the 26cm or 35cm
double D coil. Ferrous metal objects like iron for example
produce a FE indication at the top of the display and
Non-ferrous metal objects like gold silver or copper will
result in a NON- FE icon indication when the searchcoil
is moved over the target. The two icons will turn off if
no metal is present or no double D coil is connected.
This identification facility is tuned to the ground with the
GB automatic ground balance.
INTENSITY / signal intensity bar graph icons
The signal strength will be indicated by the way of a
large bar graph in the middle of the LC Display and an
audio response from the speaker or headphones.
ARROW; AERIAL, USB icons
These icons will work together with the built- in datalogger
function which will run on a hard- and software which
comes with the X6 version. For further information please
refer to the instructions for use the LORENZ DEEPMAX
X6, six channel datalogger, Sufer and Scripter Software..
BATTERY icon
The battery condition will be displayed on the bar graph
with 5 bars located on the top of the display. Note: The
battery condition should be checked with a search coil
connected and after a few minuts of operation.
BATTERY alarm LOW BAT
Low battery condition will be indicated by a pulsed beep
sound every few seconds the LORENZ DEEPMAX X5/X6
has to be turned off when this sound appears to avoid
damage from the batteries. The pulse circuit is
automatically turned off at low battery for safety reasons.
BATTERY jack
This jack is located on the bottom of the control housing.
The plug of the supplied battery pack has to be connected
with this jack. The operation time of the LORENZ
DEEPMAX X5/X6 on a fully charged battery pack at
normal temperature range is approximately 5 to 10 hours
depending on the coil connected.
COIL jack
Search coils of different size and shape can be connected
to this jack. The search coils available for the LORENZ
DEEPMAX X5/X6 have got coded connectors to adapt
the electronics to the coil automatically. To connect a
coil plug to the electronics make sure that the plug is
fully pushed in the jack and that the sleeve is fastened
by rotating it clockwise.
Note: Any connectors should be disconnected when
planning to store the LORENZ DEEPMAX X5/X6.
HEADPHONE- jack
The supplied stereo headphones can be connected to this
jack. Any stereo headphones with 1/4 inch (6,35 mm)
stereo plugs can be connected to the LORENZ DEEPMAX
X5/X6 without any problems. The built- in loudspeaker will
be automatically turned off when headphones are connected.
Note: Special headphone-adapter plugs have to be
disconnected when using the loudspeaker.
Loudspeaker
The LORENZ DEEPMAX X5/X6 has got a built-in loudspeaker on the front which gives an audible signal when
the search coil approaches to a metal object. The audio
frequency will change with the distance between the search
coil and target for better pinpointing. Especially with two
persons operation and large diameter coils the signal from
the loudspeaker is of greate help for both persons.
the coil has to be moved over the metal object to achieve
an indication. The Number for the time delay
measurement is static and will come on when certain
intensity is reached and stays on as long as the coil is
over the target.

the retuning process is performed by the electronics at
the same time. If the LOW BAT icon displays less than
one bar afterwards or if the BATTERY alarm gives a
beep sound every few seconds, the detector should be
turned off again and the battery should immediately be
recharged with the supplied charger. The battery condition
is displayed with five bars on the top of the Display
continuously during operation.
Note: On the main electronics unit three large aluminium
plates are located, of which two get warm during
operation. Please make sure that the heat can disappear
and that the aluminium plates are not covered with a
jacket or other materials to avoid overheating the unit
or burn your skin. The unit therefore has to be looked
after during operation and should not be used in sealed
containers.
Afterwards the Detector will automatically turn to the
positions which were selected the last time the detector
was in use. While pushing and rotating the ZERO, GB,
MENU, SELECT push buttons and encoders, different
settings will be selected and will be displayed on the
bottom of the LC Display at the same time. To enter the
menu and to change a parameter go on as follows. Press
the MENU encoder for one second until one icon starts
to flash, than rotate the MENU encoder, avoiding to
push it again to find the desired function to be changed.
Use the second encoder SELECT and rotate until the
new parameter is set. To leave the MENU press either
the MENU, SELECT or ZERO button shortly afterwards.
For the first time adjust the detector as follows:
Connect a 35cm DD coil and select GND 2, SENS 3,
FREQ 9, FILTER 2,VOLUME 7, AUDIO+1, AUTO 0,
DLOG 0, LIGHT 9, TONE L. Leave the menu and hold
the coil in the air. Before metal detecting ground
balance the detector first. Press the GB button while
holding the coil in the air and wait until the arrow
changes from up to down on the display and the high
beep sounds are heard. Lower the coil to the ground
at a place with no metal and repeat pushing the GB
button. The second step of the automatic ground
balance is activated and indicated by the way of the
arrow and lower beep sounds. When the arrow
disappears the tuning process is completed and you
can move the coil upwards and downwards without
hearing any changes in the audio ticking tone.The
detector is ready for operation afterwards. If low mineral
contents of the ground are expected it is sufficient to
work in the DEL 1 mode instead of a GND
groundexcluding mode. Therefore hold the searchcoil
a few centimeters over the ground while simultaneously
pressing the ZERO button shortly. Than try to keep
the distance between the coil and the ground very
constant when searching. The DELAY Modes are often
in use with frame coils on weakly mineralized soils and
a distance of approximately 50 cm between the coil
and the ground are kept constant.
The selected audio ticking sound is audible every
second. Alter the AUDIO control for different ticking
sound if necessary.
Important note: With every retuning process one should
pay attention that no metal is in the near of the search
coil while pressing the ZERO button. It is therefore
necessary to hold the search coil far away from metal
objects and the electronics control box itself.
4. Operating procedures I
USB Jack Version X5
In order to update the firmware of the Deepmax X5 the
supplied USB- Stick can be used to flash the built- in
controllers by the way of using the newest software
version. It will take a few minutes to transfer the data.
For furthe details please refer to instructious on our
website www.metaldetectors.de
GPS Module Jack Version X6
The LORENZ DEEPMAX X6 has a built-in data logger
function in order to record different signal data during
operation. For operation a supplied hard- and software
kit will be necessary. To this jack the combined GPS
module with USB stick can be connected for further
data acquisition. In conjunction with available specially
developed software it is possible to convert stored data
to visual 2 D image or 3 D surface maps on a computer
for example.

During operation no metal buckles or shoes containing
metal parts should be worn. The same with keys, coins,
rings and watches. Every metal carried by the operator
can cause false signals, especially when they are located
near the field of the search coil. Therefore the electronics
control box has to be carried far away from the search
coil, this is especially important while searching with the
large frame mounted coils but also with the smaller DDcoils in the GND 2 mode. Never use any regular metal
screws except thin V2A or V4A steel screws with less than
6mm diameter and 50mm in length when building frames
for the cable coils.
The loudspeaker will give one “tick” every 1-3 seconds
after having retuned the detector correctly with the ZERO
button. The ”ticking-rate” can be individually tuned from
silent to a low frequency threshold tone with the AUDIO
settings. This pre-set audio tone will be recalled every
time the ZERO button is operated.
As the LORENZ DEEPMAX X5/X6 offers highest sensitivity
with correctly tuned electronics, one should check the
threshold tone from time to time during operation.
Although a constant ticking sound is not always achievable,
a threshold tone with a ”ticking- rate” will give the operator
the information that the detector works with its highest
sensitivity.
Especially for target classification and ground balancing
purposes the electronics need to be tuned for best results
(see chapter 5).
The detector is now ready for use and will indicate a metal
object immediately with an audio sound emitted by the
way of loudspeaker or headphones. The audio frequency
will rapidly rise and attains its highest frequency when the
search coil is directly over the target. The centre of the
search coil is the part with the highest sensitivity. Even in
the direct near of the target frequency changes make
pinpointing possible.
The detector works with highest sensitivity in position DEL
1 for small coils and DEL 2 for large frames. When
changing the search coil the electronics need always to
be retuned via the ZERO button. When lowering the
search coil to the ground an audio sound may appear,
this can be canceled out by pressing the ZERO button
again. The distance between the search coil and the
ground has to be kept at a constant height when searching
afterwards. When working with small searchcoils of up to
45cm diameter it is also possible to select the AUTO
function with AUTO 1 for slow and 5 for very fast automatic
tuning in order to retune the electronics to changing
ground conditions automaticaly during operation. The
search coil therefore has to be moved at constant speed
to achieve a signal from metal objects. When resting the
coil over the target the AUTO function will cancel out the
signal after a certain time.
In the DEL modes large diameter coils like the frame
mounted cable coils should be hold at heights of (10 to
60 cm) over the ground to ignore magnetic mineralised
ground or small unwanted metal objects. Those coils
should be moved slowly without any jerky movements,
parallel to the ground and at constant height.
When many small unwanted bits and pieces and very
strong wanted signals are expected at the same time it
may be advisable to select a higher delay setting like DEL
3 for example.
In DEL 3 mode and specially while using large diameter
frame coils the sensitivity to very small objects significantly
decreases. This is in many cases desirable, although the
general sensitivity will be less. The simplest way to ignore
small metal objects is to increase the distance between
the search coil and the ground. Simply raise the loop and
it will still be possible to locate those deeper bigger targets.
Be always sure that there is a sufficient distance between
the detector or battery and the frame coil when raising
the loop.
Note: The LORENZ DEEPMAX X5/X6 metal detector has
to be retuned with the ZERO control every time a different
coil has been connected. During operation only a few
threshold corrections are necessary.
Position DEL 1, GND 1 and GND 2 with DD coil offer
the greatest sensitivity especially for very small non-ferrous
metal objects like coins and nuggets. To record the
conductivity (derived from the time delay of the eddy
currents produced by the targets) or to distinguish between
a ferrous and non-ferrous metal targets please refer to
the next chapter.
5. Operating procedures II
This chapter is a kind of summary how to proceed with
the LORENZ DEEPMAX X5/X6, when locating metal, while
using the two target classifications, intensity reading and
the audio signal.
It is therefore in some cases possible to predetermine the
exact position, the probable detection depth as well as
the kind of metal located. A specially developed electronic
circuit makes time delay readings possible which are
directly displayed on a scale of 000 to 099. Those so called
conductivity readings are only known from VLF TRMachines but not from metal detectors based on the
Pulse-GBS principle. In general these readings are based
on object’s size, conductivity and permeability of the target
and therefore named time delay readings for simplicity.

Please proceed as described in chapter 4 and follow
these additional instructions listed below.
Two person operation is necessary when using frame
mounted coils. The coil has to be hold with two adjustable
carrying straps at a constant height over the ground.
The search mode can now be selected to a DEL or GND
setting.
When having done this it is important to retune the
electronics with the ZERO-control. Proceed as described
in chapter 4 and hold the search coil or frame over the
ground while pressing the ZERO button.
When lowering the search coil to the ground an increasing
ticking-rate of the audio can be audible in some cases,
especially when DEL 1, 2, 3, 4 is selected.
This can either be generated by a metal object or
mineralised ground. When expecting mineralised grounds
with high iron oxide content the search coil can simply
be raised again, (10 to 50 cm) depending on the coil
and the LORENZ DEEPMAX X5/X6 can simply be tuned
to the ground conditions while holding the coil at a
constant height and pressing the ZERO button shortly.
Pay special attention to metal objects in the near of the
search coil which may cause false signals and therefore
a false retuning process.
Note: It is always advisable to carry the detector and
the separate battery pack as far away from the search
coil as possible. This is absolutely necessary to avoid
false signals caused by metal parts of the electronics
control-box.
The search coil should be held at a constant height while
searching. In many cases it is advisable to search in a
systematically manner with a certain grid which can be
marked on the ground for example.
The small (26cm ; 35cm ; 45cm) diameter search coils
can be supplied with a telescopic S- pole which is held
at constant height and in parallel to the ground. The
coils have to be moved from side to side with overlapping
tracks to detect even the smallest metal pieces which
can sometimes only be detected in the centre of the
search coil as this is the most sensitive part. Although
the response speed of the LORENZ DEEPMAX X5/X6 is
very fast, the search speed should not exceed 2 meters
per second.
When a metal object is located try to find the place with
the strongest signal which means highest indication on
the INTENSITY bargraph and highest audio frequency.
Size, shape and depth information can be derived from
the audio sound in some cases with some experience.
Small objects like single coins will be indicated with a
short and intensive signal when a small coil is used.
Coins and nails and very small pieces of metal will cause
two indications when passing them with a frame mounted
search coil (1 m x 1m) for example. This is mainly
because those small objects are out of the range of the
large coils and therefore will only be indicated at the
edges of the frame coils and only when they are very
close to it. Large metal objects will give an extensive
signal with a longer duration, and therefore can easily
be identified.
Deeply buried metal objects will generate a weak and
slowly increasing audio sound and intensity meter
reading. Objects which are close to the surface generate
a strong and rapidly increasing signal.
Large objects will cause a signal with a long duration
especially when located with large frame mounted cable
coils. For example a metal box 20cmx20cm can give a
signal of up to 6 m in length when passing with a (2 m
x 2 m) coil for example. It is therefore necessary to find
the center of a buried object by the way of the audio
and INTENSITY bargraph. This is achieved by moving
the coil from different directions slowly towards the
strongest indication. In many cases it is of great help to
use an additional smaller coil when pinpointing a target.
The centre of the search coil is always the most sensitive
part.

These different filters can be selected with MENU and
SELECT in order to cancel out signals from magnetic soils
or single stones with high iron oxide contents. Even some
iron objects can be discriminated/ eliminated by the way
of the same functions.
For automatic tuning purposes please go on as follows.
Select the GND settings 1, 2 or 3. Hold the searchcoil
horizontaly about 1m over the ground where there is no
metal. Press the GB button and wait until the first tuning
process is finished in the air. Lower the coil to the ground
and press the GB button again while keeping the coil
close to the ground. When pressing the GB button the
arrow on the display points up and down as long as the
tuning process is working. High and low beep sounds will
indicate the same.During that time no movements of the
coil should be done. Afterwards the detector is ready for
use and there should be no indications of the ground
when changing the distance between the coil and the soil.
During operation it might be necessary to retune the
ground settings from time to time. Therefore use the
automatic tuning process as described before or try the
manual tuning as follows. Therefore lower the coil to the
ground or hold directly on a magnetic stone. An audible
sound will appear most likely. When having selected the
GND 1 function the signal can be completely canceled
by adjusting the corresponding G1 control to either the
left or right direction. When approaching to the minimum
indication the audio will disappear. When moving the
control further, a signal will be audible again. Try to find
the place with the lowest indication and leave the control
in this position. The position of the rotary control is
displayed on the meter with a Number and G1 or G2.
The Ground settings can only be altered when the Menu
is off. Therefore avoid pressing those controls when
changing the position.It is essential that the detector run
through a complete automatic tuning process first, before
tuning manually.
The LORENZ DEEPMAX X5/X6 should now be silent even
if the coil is raised in the air or lowered to the ground
again. If still indications occur it may be possible that the
Detector has been tuned to a piece of metal in the ground.
In this case simply repeat the same procedure at a metal
free place. The tuning process is the same with the second
ground canceling circuit GND 2 and could be performed
with the G2 control after having turned on the GND 2
function. Both filters could be selected at the same time
to achieve highest sensitivity for most types of metal
objects when GND 3 is selected and a small or large
search coil is connected. The Detector will distinguish
automatically between the two signals and will use the
stronger signal of the two. In most cases however the
GND 1 function will be sufficient. In the case of a connected
DD coil GND 2 and GND 3 work differently. It is not
necessary to run through the whole tuning process every
time the ground properties changes. It is also possible to
alter the settings of the two controls G1 and G2 when
GND 3 icon is on the Display and the coil is lowered to
the ground. When changing the coil the ground
compensation has to be retuned again. If changing ground
conditions are expected the 35cm double D-coil and
GND 1 position will be the best choice. When Double D
coils are in use the GND 2 function works differently
compared to the previous explained single coils. The
detection depth to many non- ferrous metal objects will
significantly increase when GND 2 is in use with that coil.
In some cases however temperature changes might cause
a drift of the audio and the detector therefore has to be
retuned with the ZERO button from time to time or the
AUTO function has to be selected to cope with this matter.
When having selected the AUTO function some iron
targets will respond with a slowly decaying double or triple
signal every time the coil passes a metal object.
With turned on GND – function the LORENZ DEEPMAX
X5/X6 works with either reduced or higher sensitivity
compared to DEL Delay functions. Some iron objects and
very few non-ferrous metals with a similar signal response
as iron will be indicated less sensitive with small or large
coils. It is even possible to eliminate large or small iron
objects when selecting a special GND setting. Signals will
still occur when the distance between the coil and the
target is too small because of signal overload. However
most metal objects will be detected with almost the same
or even higher sensitivity as without ground balancing
circuit. An increase in interferences with turned on GND
function due to powerlines and radio transmitters will be
realized. The amount of interferences could only be
reduced by the way of changing searchcoils or setting the
FREQ Frequency control to a different position.
When having found the place with the strongest
indication the time delay indication will come on with
a number when the signal is strong enough. When
double D coils are in use an additional FE ferrous /
NON-FE non-ferrous indication will appear on the
LC Display. Therefore the Deepmax X5/6 has to be
ground balanced with the GB control first as shown
in the next chapter to avoid false indications produced
by the ground. Larger ferrous metal pieces will also be
indicated as being non-ferrous.

5.2. Target classification
13
In order to get further informations from the buried
metal object the target classification can be used. The
two target classification features offered with the LORENZ
DEEPMAX X5/X6 are based on different working
principles. The time delay reading is static therefore no
motion of the coil is required to make a reading 000 to
099 possible. This is especially of great advantage when
identifying deeply buried metal objects with the highest
sensitivity possible. The calibrated target classification
will directly display the time delay with all coils connected.
The conductivity reading is very precise. It will be stored
as long as the coil is over the target and will disappear
when passing the target with the coil. The FERROUS /
NON-FERROUS indication is a motion type which will
appear with the 26cm or 35cm double D coil connected
only when the coil is moved over the target. Weak signals
which are out of the range of the target classification
can not be identified.
When having located a target proceed as described in
the following steps:
Afterwards the coil can be lowered to the ground
towards the target until another meter reading is
performed by the LORENZ DEEPMAX X5/X6.
Note: The TIME DELAY indication can also be locked near
000 when very small coins, foils or gold nuggets are
indicated. This target classification will work in any position
and with any searchcoil connected.
Note: Especially when expecting very strong signals and
mineralised soils at the same time it is often advisable to
hold the coil at a higher distance over the ground. This
will help to ignore magnetic soils, because the coil is out
of the range of the ground.
This will increase the performance and accuracy of the
classification circuit and makes it easier to locate and
identify these targets. In most cases however a special
circuit will suppress the false readings derived from magnetic
soils effectively, even if the coil is close to the ground.
When expecting very deep targets it will sometimes not
be possible to perform a reading because the indication
is always about 30 to 50 % less sensitive than the audio
signal or intensity bargraph.
Some smaller pieces of bronze may be indicated with a
time delay reading between 50 and 60 namely the same
as some ferrous metal objects. At the same time the
LORENZ DEEPMAX X5/X6 does not suffer from anomalous
effects like VLF-TR- sinewave detectors do. Therefore very
big ferrous metal objects will not cause a higher reading
than 60 in most cases. If ferrous and non-ferrous metal
objects are simultaneously located by the search coil the
target classification circuitry will display the conductivity of
the larger metal object on the screen. The reading may
also lie between the two different kinds of metal.
The time delay target classification of the LORENZ DEEPMAX
X5/X6 will work with all available coils. It is capable to
identify deeply buried big metal objects and small objects
near the surface. The universal cable coils (8m or 12m)
should not have more than three windings (turns) for
identification purposes. It is often helpful to start with “inair” tests in order to see how the detector responds to
different metals.
It is necessary to find the centre of the target. The search
coil therefore has to be crossed directly over the target in
order to find the point with the strongest signal. Highly
mineralised soils, electromagnetic interference from power
lines or transmitters can cause inaccurate conductivity meter
readings especially in urban areas.
Some nails or longer ferrous objects produce different
signals when passing them with the coil.

lSlowly move the search coil from the side at con-
stant height towards the located target. Try to find
the centre of the target with the audio signal. As
soon as a certain intensity of the audible signal is
reached a time delay reading will be performed
by the LORENZ DEEPMAX X5/X6 automatically. This
will be indicated with a number between 000 and
099 on the screen.
lCompare the displayed number with the following
table. Therefore the search coil must be held over
the target on the ground in order to store the
conductivity value. For better accuracy the
conductivity reading can be repeated. Therefore
the coil has to be raised in the air or moved to
the side until the first reading disappears.

6. Searchcoils/Accessories
14
Different search coils can be connected to the LORENZ
DEEPMAX X5/X6 for special search and location purposes.
In general small search coils offer great detection depths
on small metal objects while large search coils offer the
highest possible detection depths on big objects. The
possible detection depths also depend on the setting of
the detector, the kind of metal, the shape of the metal
object and slightly on the type of ground below the search
coil. The low sensitivity for small metal pieces in conjunction
with the very high sensitivity for bigger and deeper targets
make the LORENZ DEEPMAX X5/X6 especially useful when
using it with large frame mounted search coils. The
maximum detection depths achievable with a 1m x 1m
frame mounted search coil are very high and can be
increased when enlarging the search coil to 1,5m x 1,5m,
2m x 2m or 3m x 3m. Of course it will no longer be possible
to detect single coins or nails with those large frame
mounted search coils. In this chapter different search coils
available with the LORENZ DEEPMAX X5/X6 are described.
(see chapter 10 for detection depths)
26 cm search coil
This search coil was mainly developed for the location of
very small metal objects which are close to the surface like
coin sized metal objects for example. The maximum
detection depth is limited by the size of the object and the
coil.
This search coil can be useful while pinpointing large metal
objects which have been located with a frame mounted
search coil before. Deeply buried metal objects can be out
of the range of the small 26 cm search coil and therefore
can only be detected with frame mounted search coils.
The 26 cm search coil is waterproof and therefore can be
used in saltwater for example.
Note: When expecting heavily mineralised soils it is
necessary to tune the detector to the ground first as
described before.
The FE/ NON FE, FERROUS / NON-FERROUS target
identification is of great help when classifying smaller
objects in weakly or medium mineralised soils.
35 cm - search coil
This highly sensitive search coil has got very good depth
capabilities on single coins and medium sized objects.
A telescopic pole with armrest (accessory) is necessary
for any of the small search coils (26 / 35 / 45 cm).
26cm double D search coil
A special double D version of this coil with separate
transmitting and receiving coils is also available. This coil
makes FERROUS / NON-FERROUS indications on the
display of the LORENZ DEEPMAX X5/X6 possible.
Note: The electrical properties of the double D search
coils may change when mechanical tension is produced
in the coil when being used not properly. Searchcoils
therefore are not covered by warranty for that reason.

Universal cable coil 8 m perimeter

8 m perimeter (3 windings)
The 8m universal cable coil has to be arranged to a
3 winding search coil and has to be fixed on a 0,67m
x 0,67m frame made of PVC-tubes for example.
Never use any regular metal screws for the
construction of a frame! Only V2A or V4A screws with
less than 6mm diameter and less than 50mm in
length may be used to fix the frame. This is the
smallest frame mounted search coil which offers
extreme detection depths for smaller and medium
sized objects. Metal fragments and some coins will
still be indicated. The maximum detection depth is
limited below the bigger frames but higher than with
a 45cm diameter coil. This 0,67m x 0,67m coil receives
less interference from power lines or transmitters
than larger 1m x 1m or 2m x 2m coils do.
45 cm - search coil
This search coil can be operated by a single person with
the S-rod-handle. It offers extreme depth ranges on either
single coins or bigger objects buried deep in the ground.
Depth ranges of more than 1 m for a metal object of the
size of a soft drink can (0,33 l) or up to 50 cm on a single
gold coin with 25 mm diameter make this coil interesting
for a lot of different search and locating purposes
Those extreme depth ranges on medium sized and bigger
metal objects make frame mounted search coils
unnecessary in some cases. Small items can be eliminated
by increasing the distance between the coil and the
ground. This 45 cm coil covers more ground than a
26 cm coil does and therefore makes very effective
searching possible.
Those small objects can easily be identified by the way
of the target classification. Coins with a diameter of less
than 15mm should rather be detected with smaller search
coils.
35cm double D search coil
Separate transmitting and receiving windings offer
more stable operation on soils with changing contents
of iron oxides (minerals) in some cases. Pinpointing
small metal pieces is easy with this coil, which can be
used for most search applications. The FERROUS /
NON-FERROUS target identification does only work
with the 26cm and 35cm double D searchcoils.
Note: The electrical properties of the double D search
coils may change when mechanical tension is produced
in the coil when being used not properly. Searchcoils
therefore are not covered by warranty for that reason.
This extremely lightweight and easy to transport
universal cable coil offers a variety of different search
coils for different search applications. The cable coil
has to be fixed with tape on a frame which can be
made of PVC-tubes for example. The following search
coil configurations are mainly useful for the location
of metal objects with a surface of at least 6 cm x 6cm
or hand sized metal objects for example. Small metal
pieces like single coins or nails will be indicated with
poor sensitivity or will even be eliminated in some
cases because they are out of the range of those
frame coils. It is very easy to cover a large area with
frame coils in a short time. This is especially useful
when looking for bigger deeply buried metal objects
while ignoring those smaller metal pieces at the
surface.
The following frame mounted search coils have to
be carried by two persons with adjustable carrying
straps. The search coil should be hold in parallel to
the ground at a constant distance of 10 to 60 cm. The
electronics control box should always be carried far
away from the field of the search coil. It is also
necessary not to wear any clothes with metal when
operating the LORENZ DEEPMAX X5/X6 to avoid false
signals.

1m x 1m universal cable coil
8 m perimeter (2 windings)
The universal cable coil has to be arranged to a 2 winding
search coil and has to be fixed on a 1m x 1m PVC- tube
frame for example.
Searching with the 1m x 1m frame coil is mainly advisable
when looking for hand sized or bigger metal objects buried
deep while ignoring small coins, nails and pieces of foil
at the surface of the ground. The possible detection depths
with this particular frame coil are very high compared
with standard sinewave VLF-TR-detectors (see chapter
10). This is one of the reasons why this particular search
coil is used for most professional applications.
The detection depths are in some urban areas where a
lot of small iron pieces are present even higher than those
achievable with much more expensive magnetometers
which can detect ferrous metal objects only. The LORENZ
DEEPMAX X5/X6 is specialy sensitive to many non-ferrous
metal objects no matter which coil is connected.
Large areas can be covered in a short time. Best results
are achieved with metal objects having a surface of at
least 10cm x 10cm.
Because of the size of the coil most of the small metal
fragments will be ignored. However bigger nails can be
identified with the time delay target-ID. Most of the nails
and other metal fragments can be easily eliminated by
increasing the distance between the search coil and the
ground. Even at distances of up to 50 cm there will only
be negligible detection depth losses when locating large
metal objects. This frame coil has to be carried by two
persons with the supplied carrying straps.
The high depth range of the 1mx1m frame coil is achieved
with intense and therefore deep going magnetic field
transmitted. The detection depths listed in chapter 10 have
been recorded with different DEL Delay and GND Ground
settings. In some cases detection depths in wet, conducting
ground are slightly higher or lower than listed.
For even higher Detection depths use the 12m cablecoil
which can be arranged similary to the 8m cablecoil to 1m
x 1m, 1,5m x 1,5m and 3m x 3m.

1m x 1m frame coil
This is a very user friendly 1m x 1m coil with the same
electrical properties as the 8m universal cable coil with two
windings as described before. The main advantage of this
particular search coil is its simple assembly, which can be
performed in a few steps. The disassembled coil is easy to
transport and will always be ready for use.
The coil cable is protected inside the tubes and therefore
can be used even under the worst environmental conditions.
Two adjustable carrying straps are supplied with every frame
coil.
2m x 2m frame coil
The 8m universal cable coil has to be laid to a single turn
on a metal free frame and has to be fixed with tape for
example.
This particular search coil covers four times as much ground
as a 1m x 1m frame coil does. It should only be used when
searching for metal objects with a surface of at least 20 cm
x 20 cm pointing towards the coil. Smaller targets will be
located less effectively than with a 1m x 1m frame. This is
mainly because it will become more difficult to pinpoint
those smaller objects with the large coil. The maximum
detection depth is very high and can only be increased with
the 12m cable coil arranged to a 1,5m x 1,5m or 3m x 3m
frame. Very high detection depths can be achieved when
locating large objects like several drums or ammunition
deposits or bombs buried deeply in the ground. The 2 m
x 2 m frame coil can be carried by two persons without any
carrying straps (at a distance of about 80cm towards the
ground). This is particularly useful when trying to ignore
medium sized metal objects which are smaller than a
horseshoe for example. Coins and nails will no longer be
detected when doing this.
The 2m x 2m coil acts as a large aerial for medium wave
transmitters. Therefore smaller frames like the 1m x 1m coil
will be of better choice when working in urban areas. The
next coil described will be less sensitive in general but won't
suffer from electromagnetic interference of transmitters,
power lines or the ground itself.
1m x 2m compensated frame coil
(8m cable coil)
In order to construct this compensated coil the 8m coil
cable has to be laid to the figure of the shape of an eight
(8) first. The coil cable has to be fixed on a 1m x 2m frame
with a centre part which divides the frame into two 1m x
1m frames. The cable has to be laid and fixed twice on the
centre part as this is the middle of the eight (8). This type
of frame mounted search coil is about 30% less sensitive
than a 1m x 1m search coil. This is because of the opposite
directions of the transmitted magnetic field. During the
receiving phase the two coils of the eight do also work in
opposite. Therefore interference and some ground
indications are subtracted from each other and

approaching to a metal piece located on the ground and
the upper coil will cause a signal decay when a metal
piece is approaching from the top towards the coil. This
could only be performed when AUTO / GND functions
are turned off, and DEL Delay is selected.
The sensitivity of this double frame coil is almost the same
as with the 1m x 1m single loop frame coil. This coil does
only suffer from a very weak sensitivity reduction of less
than 10 % for very deep and large metal objects. Especially
when working in the GND Ground mode it is very usefull
to work with this particular searchcoil due to very stayble
operation.
Cable coil 12 meters perimeter
1 m x 1 m (three windings)
1,5 m x 1,5 m (two windings) or
3 m x 3 m (one winding)
Similar to the 8m universal cable coil this large cable coil
can be arranged to three different frame coils by simply
mounting one two or three windings on a metal free
frame with tape for example. With the largest 3m x 3m
frame coil the highest possible detection depths of the
LORENZ DEEPMAX X5/X6 can be achieved. This is mainly
possible because of specially developed electronics to
eliminate low frequency interference and a power pulse
circuit built- in the LORENZ DEEPMAX X5/X6. The high
sensitivity for large and deeply burried metal objects and
the simple elimination of smaller metal fragments make
these three coils interesting. The shape of these large coils
should be the same as with the other coils namely round
or square. It is also possible to build eliptical or different
shapes but this is only achieved at the expense of sensitivity.
Anyway it is advisible to keep a distance of at least 20 to
80 cm constantly between the coil and the ground to
reduce the amount of ground effects to a minimum when
using these very large coils. In urban areas the amount
of interferences produced from power lines will be higher
than with smaller coils and therefore again the sensitivity
might be reduced. The ground balancing system GND
1, 2, 3 should be changed to DEL 1-4 in some cases
using these large coils because of the same reason. Some
customers use these large frame coils with two similar
coils mounted on each other at a distance of about 60 to
70 cm the same way as the differential double frame coil
described before. A Y- adapter cable would be necessary
doing this.
therefore eliminated. Interference from radio transmitters
or power lines will be almost completely cancelled. Highly
mineralised grounds will be indicated less sensitive than
with a 1m x 1m search coil. This compensated 1m x 2m
frame mounted search coil is of great advantage when
locating metal objects in urban areas where interferences
are often expected. This type of coil has a very poor
sensitivity for small metal objects. The minimum surface
of a metal plate should be 10cm x 10cm to ensure good
results when working with this coil.
Although being less sensitive, the compensated 1m x 2m
coil offers good detection depths on most types of ground.
The LORENZ DEEPMAX X5/X6 will work very stable with
this particular coil. The maximum detection depth is limited
and below a 1m x 1m frame coil.
Further informations concerning the detection depths
with different coils and DEL Delay settings are recorded
in chapter 10.
The following described 1m x 1m double frame coil will
give much higher detection depths namely almost the
same sensitivity range as a single 1m x 1m frame but is
also capable to cancel out said interferences.
1m x 1m double frame coil kit
This specially designed double frame
coil kit basicaly consists of two 1m x
1m frame coils mounted on each
other at a distance of approximately
55 cm. Because of its ability to cancel
out interferences from power lines
or radio transmitters it can be used
in urban areas where single loop coils will suffer from false
signals.
The two coils receive the same amount of interference but
work in opposite directions. Therefore almost any interference
is substracted from each other while signals from the ground
or metal object will pass to the electronics. It is important
that the components of the double frame kit are put together
in the right order as described below. The available kit
consists of the following components: two 1m x 1m frame
coils; four black mounting devices 0,6m length; one Y
adapter cable with three connectors; two carrying straps.
The two 1m x 1m frames have to be mounted on each
other via the four mounting devices. They will automatically
lock when pressing them together.
Please make sure that both frames go in the same direction,
so that the two yellow marks are pointing to each other the
same way! Afterwards the marked adapter plug has to be
connected to the lower frame which points to the ground.
The second frame has to be connected to the other adapter
plug. The third connector has to be connected to the
electronics control box.
Note: It is usefull to make an operating test where the
lower searchcoil pointing to the ground gives a signal when

The LORENZ DEEPMAX X5/X6 is supplied with an external
rechargeable battery which will power the electronics 5
to 1 0 hours depending on the coil connected and the
environmental temperature conditions. The usage time
will be 8 hours under average conditions.
A discharged battery should be recharged with the
supplied charger. Therefore the plug of the charger has
to be connected to the plug of the external battery pack
and the AC- plug of the charger to the mains. The charge
electronics will automatically change to a trickle charge
mode when the battery is full. The battery is therefore
protected and can't be overcharged. The different charge
modes are indicated via the orange / green light on the
charger. A permanent rorange light indicates the standard
state- charging. A green light indicates charging finished trickle charge.
The maximum recharge time is limited at 10 hours on
an empty battery. The rechargeable battery pack can be
recharged at any time even if it is only used for a few
minuts and the capacity is still very high.
Note: Never forget to turn off the detector immediately
after the audio beep alarm sound comes on to protect
the battery pack. The detector will automatically turn
off the transmitter when the battery is lower than 8Volts
for safety reasons. The Detector still has to be turned
off afterwards.
The following safety information must be read before
using the charger supplied with every LORENZ DEEPMAX
X5/X6 detector:
lplease read the user instructions before using the charger
lfor indoor use only (protect against moisture)
lnever try to charge ordinary non-rechargeable
batteries!
ldo only use to recharge 12V/ 7,2Ah Panasonic

When disconnecting the charger from the mains it is
important to disconnect the plug from the battery pack
as well to avoid a slow discharge of the batteries. The
supplied charger has got a wide range of input voltages
in order to fit with any country mains. In conjunction
with the interchangeable AC- plugs it is designed for
world- wide operation. Four different detachable ACplugs are available at the manufacturer of the LORENZ
DEEPMAX X5/X6 namely: USA, UK, Europe, Australia.
Note: Only spare parts and accessories available from
the manufacturer of the LORENZ DEEPMAX X5/X6
should be used.
To guarantee a long lifetime of the battery pack it should
never be completely discharged, as this can result in a
loss of capacity or complete damage of the battery.
Note: Do never forget to turn off the LORENZ DEEPMAX
X5/X6 when it is not in use or when planing to store it.
Disconnect all plugs from the control box when
transporting or storing it.
The capacity of the built-in battery can always be checked
when turning the LORENZ DEEPMAX on with the Battery
icon on the top of the LC Disply. If it is lower than 2 bars
the battery is nearly empty and less than 1 hour usage
time can be expected. When disregarding the beep alarm
tone the battery can be completely discharged. Resulting
damages of the battery can not be covered by warranty.
The battery pack can be recharged at any time no matter
if the battery pack is already full or empty.
The life time of the supplied battery pack is limited to five
years. After this period of time the capacity of the battery
will constantly decrease, which makes an exchange
necessary.
In order to exchange the battery simply disconnect the
battery connector from the electronics control box and
open the battery compartment on the rear of the belt.
When exchanging the battery make sure that only the
original 12V / 7,2 Ah battery available from the
manufacturing firm of the LORENZ DEEPMAX X5/X6 is
connected to the electronics.
Note: Please make sure that the connector of the battery
pack is always kept clean and that no conducting
material is in the near of the connector when storing
it. It is always necessary to take special precautions of
avoiding short circuits when
handling with battery- packs!

The LORENZ DEEPMAX X5/X6 was developed to
ignore most magnetic interference received by the
search coil. In some cases however there is very
strong interference produced by power lines, railroad
tracks or transmitters which are very difficult to
suppress with electronic circuits as they are many
times more intense than a signal received from a
metal object for example. Several filter circuits have
been added to the LORENZ DEEPMAX X5/X6 to
suppress most low frequency induction. Especially in
the near of power lines interference can be noticed
with false signals or rhythmic signals which cause
indications on the screen or an audio response.
In urban areas, near transmitters or when other metal
detectors are working close to the LORENZ DEEPMAX
X5/X6 interferences could also be expected. In general
interference will increase with the size of the search
coil. Interference received with large coils is often
accepted in respect of the high sensitivity still offered
with those particular coils. In some cases interference
can be so intense that it is simply impossible to work
with the LORENZ DEEPMAX X5/X6. Therefore it will
sometimes be necessary to change the frequency
with the FREQ Frequency of the LORENZ DEEPMAX
X5/X6 to suppress some interference. The FREQ
Frequency function can therefore be turned to a lower
or higher setting, until the audio sound is clear and
without any rhythmic pulses. The sensitivity or the
target classification won’t be affected when doing
this.
For further reduction of any pulsed interferences put
FILTER to a higher setting but this will also result in
a slower response speed which makes only sense
with frame coils but not with smaller coils.
If it is not possible to reduce or eliminate interference
by changing the frequency and filter of the LORENZ
DEEPMAX X5/X6 it is either possible to put the AUDIO
and SENS Sensitivity to a lower setting until the
”noise” disappears or to change the size or kind of
the search coil. When setting the AUDIO setting to
- the sensitivity of the LORENZ DEEPMAX X5/X6 will
be slightly reduced, but the amount of false signals
will also be greatly reduced. When connecting a
smaller search coil the amount of interference can
also be reduced. The compensated 1m x 2m frame
mounted search coil or the double frame coil do not
suffer from interferences, false indications are simply
reduced when using these coils. This will always
guarantee a very stable operation of the LORENZ
DEEPMAX X5/X6 even under the worst environmental
8. Interference
conditions like temperature changes, mineralised
grounds or magnetic disturbances. For the detection
of smaller objects the available 1m x1m double frame
coil should be rather used than the compensated 2m
x 1m (eight (8) shaped) coil. This specially designed
frame coil is capable to eliminate interference while
offering detection depths similar to a single loop 1m
x 1m frame coil. Especially when working in the GND
mode this coil is the best choice, as the electronics
need a signal free of interference to be able to cancel
out the ground and to distinguish between metals.
Note: Low interference with clear audio response
and correctly tuned (zeroed) electronics is absolutely
necessary to make exact target classifications and
ground excluding functions possible. The LORENZ
DEEPMAX X5/X6 has to be tuned and the right coil
has to be chosen first before starting to identify metal
objects.
The electronics unit of the LORENZ DEEPMAX X5/X6
does not suffer from any drift in general. That means
only in case of extreme temperature changes the
electronics have to be retuned with the ZERO button.
The same should be done after the very first five
minutes of operation since many components inside
the LORENZ DEEPMAX X5/X6 control box need to
warm up to their working temperature. When working
with small handheld search coils the AUTO function
can also be used to make the detector respond more
stayable.
Ground signals which are mainly derived from
magnetic iron oxides will be indicated with an
increasing audio response when lowering the search
coil to the ground although no metal is below the
search coil. This kind of ground indication can be
simply eliminated by simultaneously holding the
search coil at constant height over the ground and
pressing the ZERO push button for a second. (see
chapter 4, 5 for further details)
As long as the coil is hold at the same height during
searching there will be no loss in sensitivity after
having retuned the detector to the ground. When
expecting highly mineralised ground it is always
advisable to turn on the built- in ground balancing
System (GBS) with the GND function turned on. For
further description refer to chapter 5.1.

11. Instructions for use:
Data logger, Surfer and Scripter Software
To generate colour, image, surface or contour maps with
the Lorenz Deepmax X6, additional Hard- and Software is
necessary. A very sophisticated data logger function of the
Deepmax X6 metal detector together with an USB 6 channel
data logger will take simultaneously six channels of data
when you go over the ground and stores the information
into memory when this function is selected.
After recording or collecting field data the Surfer Software
easily and accurately transforms the data stored on the
USB-Stick into colour, contour, surface, image or vector
maps on a computer in minutes.
An additional Scripter Software will therefore automatically
generate twelve maps with each field. Six are twodimensional and six three-dimensional. The operator can
therefore choose between different gridding and mapping
methods.
The new Datalogger Hard- and Software developed by
Lorenz Detecting Systems is first of all easy- to use, very
accurately working and affordable. Only four controls of
the Deepmax X6 will make data acquisition a pleasure for
both beginners and professionals like engineers, geologists,
archaeologists, scientists and many more. The users will
investigate mainly for waste disposal, meteorites, unexploded
ordnance, or lost aircrafts.
No non- sense functions will confuse the operator. Six
different maps will be generated simultaneously when
covering the ground with multiple tracks. Each scan/ map
is different depending on the electronic analysis method
and therefore will not only give different sensitivity ranges
but can be the key to the probable kind of metal buried
in the ground. There is clearly a difference in the signature
metal objects and ground conditions will give for example.
Areas of disturbances in the scans will directly lead to the
different metals or ground signals and therefore can be
classified in some ways. The operator therefore can use
the different scans to his advantage in order to choose
between the targets of most interest only by comparing
the different scans/ maps. Three delay channels will produce
maps with different sensitivity to small and large metal
objects. Two ground channels will enable the operator to
generate maps with no ground response but Z dimensions
and directions for different decay curves of the eddy currents
produced in a metal object. In addition the target
classification channel will display the delay of the eddy
currents of each signal with a certain intensity to give further
information on the probable kind of metal in the ground.
No matter how strong the ground is mineralised or how
many different metals are located in close proximity, this
new device will ensure very good results even with difficult
surrounding conditions. Faults produced by the operator
or the environmental conditions like overload signals from
nearby metal objects for example will be immediately seen
when comparing the six channels. In addition GPS data is
also recorded from a supplied GPS module to support the
user with a compass function or to find the different fields
after recording again.
For the professional users additional Hard- and Software
will be available for storing positioning data from GPS and
several Deepmax X6 detectors.
Although the detector can be used with smaller search
heads the data logger function is mainly developed for
larger metal objects being at least 6cm x 6cm in size.
Therefore frames of 1m x 1m or even bigger should be in
use to achieve best results.

Operating procedures:
To record field data, find a starting point where X and Y
lines will meet. Put a mark on the ground to find this place
again. Put additional marks in the corners of a rectangle
where you plan to have a field for searching. For best
results cover an area of less than 20 m x 20 m. Different
field sizes measuring 10 m x 20 m for example are possible
as well. Try to make marks for each line that means every
1m in X direction when planning to work with a 1m frame
coil.
Make sure that you start in the left corner of the new field
with the first track! See and compare to the pictures!
Afterwards you will slowly cover the ground from the left
to the right, step by step with each track you are going.
1. To start collecting field data first connect the GPS
module with USB stick and the Detector itself. The USB
module has to be mounted on the shoulder of the operator
with the transparent part pointing up. Connect a search
coil (frame coil) and battery pack, turn on the unit and
make sure that the data logger DLOG is turned off DLOG
0.
2. Hold the frame coil in the air, far away from any metal.
Push the GB Ground button once and wait until the beep
sound is completed. Lower the frame coil to the ground
at a distance of approximately 10cm over the ground and
press the same GB button a second time and wait until
the lower beep sounds indicate the tuning process is
completed.
3. Press the MENU control for approximately 1 second
to start the menu. Select DLOG 1, M for meter indications,
FREQ (any position that looks silent on the bar graph)
VOLUME (adjust to desired setting) and leave the menu
by pressing MENU/ SELECT or ZERO.
4. Check the icons for the field, antenna and USB coming
on. Flashing antenna means no valid GPS data available.
Flashing USB means problem occurred with storing data.
It might take some time until the GPS icon stops to flash
because of recording data.
5. Start collecting field data in the left corner of the new
field by pressing the ZERO button and immediately start
walking a straight line at constant speed. The large arrow
starts to move to indicate that data acquisition is working.
A pulsed beep sound indicates the same. A typical
walking speed not exceeding 2m/second is perfect. Try
to listen to the high beep sound every second when
walking at constant speed. Keep constant height between
the coil and the ground. As the M Meter indication is
selected the multi function display shows the meters
already being covered. A few meters have to be covered
until a proper indication is possible.
6. When passing the end of the first track Stop by
pressing the ZERO button again. A low and high beep
sound states that the first track is completed.
7. Move to the next track for example 1m to the side
and 180 degrees pointing backwards. Start and stop with
the next track the same way as the previous track,
pressing the ZERO button. A +/-180 degrees indication
comes on to make sure that you move backwards. The
multi function display counts the meters you walk back
until you reach the starting X line with 0 meter again.
In the case of an error do not press the ZERO button
to store but the GB X button to delete the last track. Go
back to the starting point of the last track and walk the
same track again pressing the ZERO button for starting
as described before.
8. A compass indication in the middle of the display
points to the direction you have to walk. For example
two square icons pointing to the right show that you are
presently not walking in a straight and parallel line and
that you have to move slightly to the right while walking
until the square icons disappear. In addition the present
Heading can be indicated on the multi function display
when HDG is selected. Therefore simply make sure that
the same Number appears when you walk on each track.
In that case again cover a few meters on each track until
proper indications can be read on the display.

In order to change from M Meter to TR Track, FI
Field, HDG Heading indication simply alter the
SELECT rotary control. This can be performed even
during the operation of the Deepmax X6. When
starting with the first track there will be no HDG
Heading available as this track is for reference purposes
only.
Design and specifications subject to change without notice!
Analyzing Field Data
To analyze the different pictures generated with the
software refer to the following instructions. Compared
to many other systems the Lorenz Deepmax X6 and
Data logger will not only generate one or several
graphic representations with different sensitivity ranges
for the same metal objects but also gives additional
information on the probable kind of metal being
located. The advantages of the six channel data logger
are as follows:
False or overload data will be easily recognized on
one or two of the maps. At the same time you will
find useful data on at least one or two channels.
When looking at the different pictures select only
these with no ground signals or with the stronger
indications to avoid investigating on the small junk
objects like foils, nails, magnetic soils or littered
ground near the surface.
• Some signals appear on one scan and disappear
on others to give the operator more advanced
information on the kind of metal (decay of the eddy
currents) or the surrounding ground conditions.
• It is possible to separate two or more different metal
objects which give only one large indication in the
Delay channels but two on the target classification or
Ground channels.
• Some ferrous metal objects lying horizontally in the
ground will cause a special triple signal with two high
and a low indication when looking at the Ground
channels.
• Signals with a fast decay of the eddy current like
foils, thin plates small nails (Target classification
Number 35 or lower) will generate a negative peak
in the vertical Z direction in Ground 1 and 2 channels,
At the same time Metal objects with a long decay of
the eddy currents like massive copper Bronze
Aluminium or silver (Target classification 40 or higher)
will cause a positive peak in Z direction. Ferrous metal
objects will only give weaker signals and therefore a
poor indication in Z direction (in the three dimensional
Surface maps only)
• When looking at the Ground channels most of the
ground and some of the smaller ferrous items will
no longer be displayed comparing them to the Delay
channels.
• On the target classification pictures stronger signals
which generate a time delay reading will produce
mainly a single colour dot corresponding to the delay
reading on the display of the Lorenz Deepmax X6.
Neutral ground will cause a purple indication. Different
nearby metal objects lying in close proximity will give
different colours in most cases for better selection.
