1.1 Preface
Dear customer,
all of the engineers, sales, training and support staff at OKM Ortungstechnik GmbH would like to thank
you for your purchase of the eXp 4000.
The eXp 4000 detector works on the principle of Electro-Magnetic Signature Reading (EMSR). Besides
the detection of metallic objects this device is also capable of detecting natural features of the earth like
formations of strata, cavities, voids, faults, ground water and other non-metallic objects. Then of course
this equipment is best suited at detecting sepulchers, treasure, buried utilities, tanks and the like.
The eXp 4000 is able to locate, document and analyze buried objects within various structures and
vessels non-intrusively without having to excavate the area. Using EMSR is particularly useful in areas
where detection is a must and excavation is not possible. The facile and flexible handling of the eXp
4000 can easily and quickly give reproducible results.
With our team of specialists we guarantee that our products are under recurrent control. Our specialists
try to implement new developments in terms of further quality improvements for you.
By purchasing or using one of our products, we cannot guarantee that during the course of your
research that you will be successful and have a find. The recognition of hidden and buried objects
depends on a huge number of factors. As you well may know there are different soil types all over the
world with different levels of natural attenuation. Variable soil properties can and will hamper and alter
ultimate scan measurements. Areas where there is an extreme amount of ground water, varying clays,
sands and wet soils making scanning more difficult and may reduce the maximum depth capabilities of
any and all detection equipment, regardless of make or model.
For more information regarding where this equipment has been used and operated, please visit our web
site. Our equipment is constantly being tested and when improvements or upgrades are available, we
will list them also on our web site.
It is necessary for our company to protect our developments and all of the information learned during
the “Research and Development” phases in creating our technology. We strive to stay within the given
framework of legislation, patents and trademark registration.
Please take your time to read this User Manual and familiarize yourself with the operation, functionality
and how to utilize the eXp 4000. We also offer training for your equipment in our factory and on-site. We
strive to maintain worldwide dealer network for assistance and support. Please visit our web site for
more information.

1.2 Important Notes
Prior to using the eXp 4000 and its accessories, please read these operating instructions carefully.
These instructions give information on how to use the detector and potential sources where precautions
should be taken.
The eXp 4000 and its accessories serve for the analysis, documentation and detection of sub-surface
anomalies and ground disturbances. The recorded data of the ground structure will be transmitted to a
PC to give a visual representation using our proprietary software program. Any additional notes to the
software should be observed. Please read the user manual of the software!
1.2.1 General Notes
Being an electronic device, the eXp 4000 has to be treated with caution and treated with care as with
any electronic device. Any failure to observe the safety precautions given or any use for purposes other
than the ones it is designed for may result in damage or destruction of the processing unit and/or its
accessories or connected components.
The device has a built in anti-tampering module which will destroy the unit if it is improperly opened.
There are no end user serviceable parts on the inside of the unit.
1.2.2 Possible Health Hazards
If used properly this device normally does not pose any health hazards. According to current scientific
knowledge, the high-frequency signals are not harmful to the human body on account of their low power.
1.2.3 Surrounding Area
When moving this unit from a cold place to a warmer place, watch out for condensation. Do not
immediately operate the unit until any possible condensation could have evaporated. The unit is not
weather proof and water or condensation can destroy the unit.
Avoid strong magnetic fields, which may occur in places where there are large electric motors or
unshielded loudspeakers. Try to avoid using this equipment within 50 meters (150 ft) of this type of
equipment.
Metallic objects on the ground such as cans, tin, nails, screws or debris can influence your scan data and
present negative results regarding your scan data. Also it is a good habit to remove any metallic objects
off of your person like cellular telephones, keys, jewelry, etc... Do not wear steel toe boots.
1.2.4 Voltage
The power supply should not be outside the indicated range of values. Use only approved chargers,
batteries and rechargeable batteries which are included in the scope of delivery.
Never use the 115/230 Volt mains supply.
OKM Ortungstechnik GmbH

10 Introduction
1.2.5 Data safety
Data errors can occur if:
• the range of the sender module has been exceeded,
• the power supply of the device or the batteries are too low,
• the cables are too long,
• the unit is operating to close to devices which sends out disturbances or
• atmospheric conditions (electrical storms, lightning, etc...).
1.3 Maintenance and Services
In this section you will learn how to maintain your measuring instrument with all included accessories to
keep it in good condition a long time and to get good measuring results.
The following list indicates what you absolutely should avoid:
• penetrating water
• strong dirt and dust deposits
• hard impacts
• strong magnetic fields
• high and long lasting heat effect
To clean your device please use a dry soft rag. To avoid any damage you should transport the device and
accessories always in the appropriate carrying cases.
Prior to using your eXp 4000 please be sure that all batteries and accumulators are fully charged. Also
allow the batteries to completely discharge before recharging them, regardless if you are working with
the external battery or with internal accumulators. This way your batteries will have a long and durable
life.
To charge the external and internal batteries, use only the approved chargers which are part of
our scope of delivery.
1.4 Danger of Explosion during Excavation
Unfortunately, the last two world wars also made the ground in many places of the world a potentially
explosive scrap heap. A host of those lethal relics are still buried in the ground. Do not start digging and
hacking for an object wildly when you receive a signal of a piece of metal from your device. Firstly, you
might indeed cause irreparable damage to a truly rare find, and secondly, there is a chance that the
object reacts in an insulted way and strikes back.
Note the color of the ground close to the surface. A red or reddish color of the ground is an indicator of
rust traces. As regards the finds themselves, you should definitely pay attention to their shape. Curved

or round objects should be a sign of alarm, especially if buttons, rings or little pegs can be identified or
felt. The same applies to recognizable ammunition or bullets and shells. Leave that stuff where it is, do
not touch anything and, most importantly, do not take any of it home with you. The killing machines of
war made use of diabolical inventions such as rocker fuses, acid fuses and ball fuses. Those components
have been rusting away in the course of time, and the slightest movement may cause parts of them to
break and be triggered. Even seemingly harmless objects such as cartridges or large ammunition are
anything but that. Explosives may have become crystalline over time, that is, sugar-like crystals have
formed.
Moving such an object may cause those crystals to produce friction, leading to an explosion. If you come
across such relics, mark the place and do not fail to report the find to the police. Such objects always
pose a danger to the life of hikers, walkers, farmers, children and animals.

7 Operating Modes
CHAPTER 7
Operating Modes
In this section you will learn more about the different operating modes of the eXp 4000. Every function
is explained in its proper subsection.
Page 46
46 Operating Modes
Selecting the correct operating mode depends primarily on the desired output. So for example there are
some functions which have to be used for an initial first measurement in an unknown area to get a
general overview, whereas others are more suitable for a more detailed search and analysis with a
special processing software program.
The eXp 4000 has the following operating modes:
• Magnetometer
Search an area with the integrated magnetometer.
• Ground Scan
Measurement with graphical evaluation, whereby measured data can be stored in the internal
memory of the device for later review.
• Metal Detector
Activate optional DDV system to discriminate between metals.
• Discrimination
Examination of detected objects regarding their characteristics on iron contents.
• Empty Memory
Delete all data stored in the internal memory.
• Exit
Power off the device and shut down the integrated PC module.
If you are connecting the optional FS-Thermoscan to the eXp 4000, there will be two more operating
modes available. Without FS-Thermoscan those functions are inactive and not visible.
• Thermograph
This operating mode is used to view and analyze differences in temperature measured with FS-
Thermoscan.
• Thermo Scan
In Thermo Scan you can create graphical infra red images to visualize the distribution of
temperatures of a field.
Both operating modes will be visible in the main menu as soon as the optional device FS-Thermoscan is
connected to the eXp 4000. These options are useful for seeking cavities.
Via the touchpad on the front of your device you can select and confirm your desired operating mode.

Operating Modes 47
7.1 Magnetometer
By selecting the Magnetometer mode from the main menu, you can scan the sub-surface for
ferromagnetic targets and areas of the soil with a high iron content. Also, you may view the oscilloscope
output on the monitor to be able to identify ferromagnetic materials in the ground.
Illustration 7.1: Magnetometer: Main Menu, Representation of Values
The Magnetomer mode can be used with all the antennas except the DDV system. As soon as you
confirm the operating mode "Magnetometer", the integrated magnetometer will be adjusted to the
current ground value of the place where it is situated at that moment. During the initialization process
the message "

When powering on the unit above a neutral soil, all metallic signatures will be shown in upward spikes.
If by mistake, you start the unit above a metal target, all like metals will not be recognized.
To re-balance the Magnetometer, press the OK button, while staying on a neutral place. To exit the
Magnetometer mode, press the or to return to the main menu.
When you use this mode, you can actually move quite quickly to clear a field of easily identified metallic
objects. Most of the time when your target may be of a newer nature or is located in an area where there
is a lot of modern construction, this is the first choice to identify potentially “Hot” targets. A hot target
can be debris like cans, nails, screws, old automobile parts, etc... These should be cleared first. The
magnetometer measures usually only near to the surface for quick hunts.

7.2 Ground Scan
This operating mode allows you to do a measurement with graphical representation whereby all
measured values will be stored in the internal memory of the device. Also you have the possibility to
recall and see previous stored graphics. This mode can be used with all antennas except the DDV
system.
The Ground Scan mode is your primary function. This is the mode where you are going to find the
targets and locate areas of disturbed soils. When something is buried, then whoever buried it had to dig
a hole. Look for the disturbance in the soil first. If a hole was created at 4½ feet (1.5m) deep, after a
couple of seasons the hole will appear to be over 6 ft (2m) in diameter at the surface. Start with a scan
that has an impulse approximately every 1½ to 2 feet (40cm – 60cm) forward and to the sides. Don't go
too fine on the first scans until you have a possible anomaly. Look for the holes! Usually without a hole
you could be looking at mineralization.

After activating this operating mode you have the possibility to adjust certain settings. There are
different parameters which influence the measurement. In figure 7.4 you can see the corresponding
submenu.
Illustration 7.4: Ground Scan – Parameter
You can modify the following parameters (the underlined values correspond to the setting made
by the factory):
• Impulse Mode (Automatic, Manual)
If you are working in the Manual mode the measured values will only be recorded when using
the joystick or by pushing on the start button. If you select the Automatic mode, the measured
values will be recorded represented on the display continuously.
• Impulses (Auto, 10, 20, ..., 50)
Number of measured values per search line. If you select "Auto" the number of impulses can be
adapted to the current length of your search line. During the first line the device will read values
regulary without stopping. When you want to finish your first line you have to press the OK key,
to stop the measuring process of the current line. The device will store the number of impulses
and use it for all further scan lines on the same scan. By selecting the value 10, 20, ... or 50 you
can preset the number of impulses you need in one measured line.

7.3 Metal Detector
To use this operating mode you have to connect the optional DDV system first. This detector is
specialized to find small objects (e.g. coins) which are located near to the surface.
Illustration 7.10: Metal Detector
Also with this detector you have the possibility to discriminate between different metals. So for example
you can find out if an object is gold, silver or iron.
Further information about the correct usage of the detector and the principle of discrimination you can
find in section "Optional Equipment / DDV system" of this users manual!
OKM Ortungstechnik GmbH

54 Operating Modes
7.4 Discrimination
This operating mode is used to identify metals and cavities. Therefore it is necessary to connect the
optional available Supersensor. If you don't have the optional Super Sensor, contemplate very seriously
on acquiring one. This is an extremely powerful function and can assist you in verifying real targets.
There are three basic modes in which you will use this function. Discrimination of course, tunnel
recognition, and then also when on the water from a boat. For water operations, please contact one of
our trainers at the factory to receive a more detailed operation. In this section we will only cover
Discrimination and Tunnel Recognition.
In this mode there is no given manner fixed or a scan direction. You can walk as you want to determine
the soil. This operating mode is most effective if you have already detected possible objects and now
want to know more details about them.
Illustration 7.11: Discrimination
The Supersensor should point vertical towards the ground. It should not be turned or pivoted.
Now you can slowly move the Supersensor from one side to another above the possible object. Please try
to capture the complete object, which means you should measure beyond the edges of the object. Repeat
this measurement a few times to get a clear signature of the object. There are 3 different signatures,
from which you can recognize a specific characteristic of any target.
Ferrom a gnetic meta ls
Ferromagnetic targets hav e a positivenegative-signature.
Illustration 7.12: Signature of a ferromagnetic metal target
The figure 7.12 shows a typical signature of a ferromagnetic metal like iron. The signature includes a
positive (red) and a negative (blue) amplitude. When looking closely you can see even 2 ferromagnetic
signatures. The first signature starts with a positive amplitude and the second signature starts with a
OKM Ortungstechnik GmbH
www.okmmetaldetectors.com
Page 55
Operating Modes 55
negative amplitude. The order is not important, it depends on the direction of movement of the
Supersensor. If you keep moving the probe from one side to another, these 2 signatures will change
continuously.
Take care to move the Supersensor slowly and at the same height above the ground and above a
detected object to get a clear signature.
Non-ferrom agne tic metals
Non-ferrous targets have a pure positive
signature.
Illustration 7.13: Signature of a non-ferromagnetic metal target
The figure 7.13 represents a signature of a non-ferrous target. You can recognize that there is only a
positive amplitude (red). Additionally to the main amplitude there is another small peak, which is
typically for precious metals. Also here the order of amplitude and the small peak is not important and
depends on the scan direction.
Non-m e tallic ta rgets
All non-metallic items have a pure
negative signature.
Illustration 7.14: Signature of a non-metallic target
The last of the typical signatures is represented in figure 7.14. It is the signature of all non-metallic
targets and structures. These can be voids, tunnels or buried plastic pipes or boxes. You can recognize
that there is only a negative amplitude (blue).

CHAPTER 8
Field procedure
This chapter gives practical instructions about the general procedure of scanning an area. The different
scanning methods and procedures will be explained in detail.
Page 58
58 Field procedure
8.1 General scanning procedure
In general every scan always starts on the bottom right corner of your scan area. Starting from this
point, you should walk scan path by scan path, whereby every following path is situated on the left side
of its previous path. During walking these lines, the measurement values will be recorded and
depending on the selected operating mode either transferred directly to a computer or saved into the
memory of the device.
The device stops at the end of each finished scan line, so that the user can find the starting position of
the next line. In this way, all paths will be recorded and the area will be measured.
Figure 8.1 shows all 4 possible starting positions and the corresponding first scanning path. Depending
on the composition of your terrain you can determine the optimal starting point for your measurement
by yourself.
3
4
Figure 8.1: Starting position of a scan area

Start of
1. scanning
path
End of

path

The scanning paths may be referred as "Zig-Zag" or "Parallel" traverses. Also the number of impulses
(measure points), which are recorded during one scanning path can be adjusted individually depending
on the size of your scan area (length of scanning path).
8.1.1 Scan Mode
There are two general techniques to surveying an area with the eXp 4000:
• Zig-Zag
The starting position of two scanning paths next to each other is on the opposite side of the
measured area. You will record data on your scanning path and on the return path as well.
• Parallel
The starting position of two scanning paths is always on the same side of the measured area. You
will only record data in one way and in one direction, while you should return and walk back to
the starting position of the next scanning path without recording data.
Figure 8.2 represents both techniques schematically.

Zig-Zag scanning
Figure 8.2: Scan modes to measure an area
1
Start of
scanning
path
End of
scanning
path
Doing the scan in "Parallel" mode you will start on the bottom right corner of your scan area (point ) to
walk and record a scan path towards the upper right corner of the area. After recording the first line,
you should walk back to the starting point and move to the left of the first scan line to start the scan
path 2 (point ), to start there the second scanning path. In this way all other paths will be scanned,
until you have reached the left side of your measure area.
Doing the scan in "Zig-Zag" mode you will start also from the bottom right side of your measure area
(point ) to walk and record a scanning path towards the right upper corner of the measure area.
Different from the parallel measurement, you should continue recording data while walking back the
second scanning path. So you go to the starting point of the second scanning path (point ) and scan in
the opposite direction. In this way, all other paths will be scanned in the scan mode "Zig-Zag" until you
have reached the left side of your measure area.
The distance between the scanning paths should be consistent during one measurement but can vary
from measure area to measure area. If you mostly look for smaller targets than you should also select a
smaller distance between the lines. A standard rule is: The smaller the distance between the paths, the
more accurate your scans will be. When you are conducting your first scans the lines should not be to
close together to locate possible targets.
8.1.2 Regulation of the number of impulses per scanning path
It is possible to select the number of impulses before starting the measurement or selecting the
automatic mode ("Auto") to adjust the number of measure points after finishing the first scanning path.
When the number of measure points has been configured, the device will stop automatically when this
number has been reached and waits for the start of the new scanning path.
In the automatic mode you should stop the measurement of the first scanning path by yourself, by
pressing the appropriate button, as soon as you have reached the end of the first scanning path. This
effective amount of measure points will be used for all further scanning paths of this measurement.
Starting from the second scanning path, the device now stops automatically after the assumed number
of impulses has been reached.
OKM Ortungstechnik GmbH
www.okmmetaldetectors.com
Page 60
60 Field procedure
Keep in mind the number of impulses which you have recorded per scanning path. This amount
should be entered later in the software program, when transferring the data to a PC, to receive
all measured data correctly from your measuring instrument!
There is no special rule for selecting the right number of impulses. But there are different aspects which
should be considered. These are some considerations
• the length of your measured area and
• the size of the objects you are searching for.
A preferable distance between two impulses is about 15 cm to 30 cm. The smaller the distance between
two impulses is, the more exactly the graphical representation will be. If you are looking for small
objects you have to select a smaller distance, for big objects you can increase the distance between the
impulses.
Figure 8.3 shows the effects of the distance and the number of impulses per scanning path for some
objects.
Figure 8.3: Effects of changing the number of impulses and their distance
Figure 8.4 shows the difference between very few impulses (left side) and much more impulses (right
side) on the same length of scanning path. Therefor the second record (right side) shows much more
details and also smaller objects can be seen.
Figure 8.4: Comparison of low and high number of impulses
Do not hesitate to record more measurements with different numbers of impulses. For example you can
scan a large area before doing a second detailed precision measurement. Especially if searching for

Field procedure 61
bigger objects you can proceed like this. With this manner you can measure a larger area very quickly
and afterward you make new scans localizing the suspect targets.
When conducting a scan it is important to not only make note of how many impulses are being used but
to get a clear picture of what you are scanning, it is very important to watch your speed. Every scan line
should be measured at the same speed as the previous line.
Figure 8.5 shows what can happen, if you walk at different speeds during your scan.

Using a different walking speed in the scanning paths, will cause displacements in the scanning path.
As a matter of fact, a target can get cut into several smaller items or completely lost because it was
missed. Later when the data is downloaded for further analysis, speed errors can make a target
completely unidentifiable and may be discarded.
In general, the following rule is valid: Keep scans at practical sizes where you can see the beginning and
stop lines and can comfortably traverse an area to keep your speed and the distances reasonable.
8.2 Special advices for field procedure
There are some aspects which you should take note of when conducting scans. In principle, a scan is
only as good as the path that was taken. Making errors while scanning will show up in the final
graphical representation also as an error. This will cause frustration and lost time.
Before you start with a measurement in the field, you should think of what you are looking for and if the
selected area is suitable. Measuring without a plan usually will produce unacceptable results. Please
consider the following advice:
• What are you looking for (graves, tunnel, buried objects, ...)? This question has direct effects on
how a scan is conducted. If you are looking for larger targets, the distance between the single
measure points and scanning paths can be larger, as if you are looking for small targets.
• Inform yourself about the area, where you are searching. Does it make sense to detect here? Are
there historical references which confirms your speculation? What type of soil is on this area?
Are there good conditions for data recording? Is it allowed to search at this place (e.g. private
property)?
OKM Ortungstechnik GmbH

Page 62
62 Field procedure
• Your first measurement in an unknown area has to be large enough to get representative values.
All further control measurements should be adjusted individually.
• What is the form of the object you search? If you are looking for an angular metal box, the
identified object in your graphic should have a form according to this.
• To get better values concerning depth measurements, the object has to be in the center of the
graphic, which means it has to be framed by normal reference values (normal ground). If the
object is on the side of the graphic and not totally visible an estimated depth measurement is not
possible and also measurement of size and form are limited. In this case, repeat the scan and
change the position of your scan area, to receive an optimal position of the anomaly inside of the
graphic.
• There should not be more than one object in a scan. This will influence the depth measurement.
It is useful to scan partial areas over such targets.
• You should do at least two controlled scans to be more sure about your results. This is also
important to recognize areas of mineralization.
• Most important rule when dealing with mineralization. REAL TARGETS DON'T MOVE! If your
target moves then it is most likely mineralization.
8.2.1 Orientation of probe
During one measurement the probe should have always the same distance to the ground. Generally we
recommend a height of about 5 – 15 cm from the surface of the ground if possible.
In the event that you are going to go over stones, wood or high grass that is higher, start your scan with
the sensor higher right from the beginning. In circumstances like these, then perhaps you will need to
start the scan with the probe at a height of 2 feet (50 cm) and keep it at that level for the entire scan. It
is important to maintain the height, this will eradicate many errors. As a rule, do not change the height
during a scan for it may create unnecessary errors.
Another important aspect is the physical orientation of the probe. During the "Parallel" scan mode the
orientation of the probe does not change because you are always measuring in the same direction. Even
in the "Zig-Zag" scan mode the orientation of the probe must not be changed. That means you are not
allowed to turn yourself with the device and the probe at the end of the scanning path. Instead you
should walk backwards and continue scanning. Otherwise your obtained graphic includes red or blue
stripes. These stripes throughout a scan are commonly referred to as “Rotational Errors”.
8.2.2 Parallel or Zig-Zag?
For skilled users of the eXp 4000 both scan modes are suitable. According to experience the best
graphics has been received in the "Parallel" mode, because you are starting at the same point and
traveling in the same direction. It is also easier to control your walking speed.
OKM Ortungstechnik GmbH
www.okmmetaldetectors.com
Page 63
Field procedure 63
Especially in uneven territories like mountain sides, acclivities or other inclined layers the parallel mode
is preferred. When it comes to speed, the experienced user will very often use the Zig-Zag mode for the
initial scan to determine if there are anomalies in the area worth further research.
8.2.3 Manual or automatic impulse mode?
Large even or passable surfaces are commonly measured in the automatic mode. The manual impulse
mode is mostly used for difficult uneven terrain, areas where there is quite a bit of growth and if the
measurement result needs to be very accurate.
In terrains with difficult access like mountain cliffs and sides, slippery surfaces or overgrown areas, it is
wise to use the manual impulse mode. Because each impulse will be released manually, you have enough
time to position the probe in the correct way and record the measured value. In this way, you can also
measure accurately previously marked dots of a predefined grid.
8.2.4 Tips from the trainers themselves
When conducting scans, there are some extremely important items that need to be noted. First of all it is
crucial that you relax. When you are tense, you are putting too much pressure on yourself to do the scan
correctly; often resulting in errors.
• Newly buried targets are difficult to see. Many users receive the equipment and the first thing
they do is go out and bury an object. When an object goes into the ground it changes the natural
signature of the soil and creates some kind of noise. Usually the buried object has a weaker
signature than the unnatural noise and therefor is not detectable. So taken scan images will not
show the buried item but visualize the noisy area in blue colors. After the item has been
seasoned, meaning it has been in the ground for a complete cycle of seasons (usually a year), the
noise gets reduced and the signature of the buried object becomes visible again.
• Train on known targets. In the training course at the factory we have several objects that have
been buried for years, just like real targets in the field. These targets can be quickly and easily
identified because they are not natural to the soil. Other targets that you can use in your own
area are buried utilities. Pipes, tanks, electrical, sewers, graveyards, etc... Most of these items
can be found in every community, town or city. This is where you need to begin your training if
you are going to self-train.
• Get professional training. When you take advantage of receiving the training, either from the
factory or a qualified dealer, you will understand not only the use and operation of the OKM
detector but also the software so much easier and be able to identify targets as well as errors.
• Do not rely on just one scan measurement. So many users go out into the field and they make a
measurement and see a target. Instead of repeating the scan and reproducing it several times,
they go out and get a shovel and dig. On very rare occasion will the first scan be perfect. Even
the trainers do multiple scans to ensure that they are not looking at areas of mineralization or an
error.

64 Field procedure
• Soil Mineralization – Oh! Very frustrating! We will all experience it. When you are in an area that
is known to have pockets of mineralization, be prepared to conduct more scans than normal.
◦ Clay is probably the number one foe. Depending on the iron content of the clay will
determine how strong the attenuation will be. A quick rule of iron content is how dark it is, it
can vary from a light gray up to a dark orange. The darker the more iron it will have in it.
◦ Sand is usually very clear and easy to hunt in. There are two factors of sand that need to be
noted. Sand where the ground water is very shallow, meaning that the ground water is
usually just a couple of meters from the surface or desert sand where it is very arid. In
desert sand, the targets can be situated 3x deeper than indicated.
◦ Farmland is another area to take note of. In modern farms, so many nutrients and fertilizers
are introduced creating an unnatural area of mineralization.
◦ Rocky mountainous areas. Areas with many mountains are also riddled with patches of
mineralization. Mountainous areas are created from faults in the earth and this is probably
the biggest area for natural treasures as well as mineralization.

9.1 Super Sensor
The Super Sensor is a hig hresolution antenna, which is specially adjusted to detect metals. Yet it is also
possible to recognize larger voids with this antenna. A particular characteristic is to distinguish ferrous
metals from nonferrous metals. This discrimination is possible in the operating mode Discrimination.
Compared to the standard Horizontal GPR-antennas the Super Sensor can find much smaller and deeper
situated metal objects.
9.1.1 Usage
The Super Sensor can be used in the following operating modes:
• Magnetometer
• Ground Scan
• Discrimination
To use the Super Sensor with the device, you just have to connect it to the main unit. Therefore you have
to plug in the connector of the antenna in the appropriate input of the device. Hold the antenna always
vertical to the ground in your hand, whereby the cable should come out at the upper end of the antenna.
The figure 9.1 shows how the Super Sensor has to be hold in a correct way.
Illustration 9.1: Position of Super Sensor
The Super Sensor should not be swinged nor moved up and down during the measurement. The more
even you hold the antenna the better will be your measured graphical results. The distance between the
ground and lower part of the antenna should be about 10 cm, but can be enlarged depending on the
terrain conditions.
The orientation of the antenna should not be changed during the complete measurement!

9.2 DDV system
With the DDV system (Disc Detector Visualization System) a powerful metal detector is on your disposal,
which not only supports your underground research with a visual representation but also offers you
various filter possibilities.
Sensitivity
regulator
LED
Discriminator
Connector plug
Coil
Illustration 9.2: Control Elements of the Detector
To use the DDV system just plug in the connector plug into the control unit of your eXp 4000. Then
select the operating mode "Metal Detector" in the main menu.
Attention: As soon as you confirm this option the ground balance will start. Detailed information
you can find in section 9.2.3 on page 70!
Now you have to pivot the detector coil continiously right above the ground, trying to keep the same
distance to the soil. Adopt the rhythm of the graphical representation on the screen. As soon as you pass
above a metallic object a yellow colored trace will appear in your graphic and you can hear an acoustical
sound through the headphones.
9.2.1 Calibration
The manual calibration is only possible for product version
product versions have to be calibrated from the manufacturer. The version of your device you can read
inside the main menu.
Before using the metal detector for the first time the DDV system has to be adjusted on the eXp 4000. If
you purchased the DDV system together with the main unit the metal detector has already been

calibrated in the optimal way. Anyway you have the possibility at any time to recalibrate the DDV
system. Therefore you have to activate at first the operating mode "Metal Detector".
Place the DDV system on the ground like shown in figure 9.3. Take care that no metal is situated near to
the coil! Press the key OK, to start the calibration.
Illustration 9.3: Calibration of the DDV system, step 1
In the first step of calibration you have to turn the sensitivity regulator completely to the right side and
so adjust it on full power. The discriminator has to be adjusted on the value 0. Take care that no metal is
located near to the coil! Now press the key OK, to start the calibration. Wait until this process is
finished.
Illustration 9.4: Calibration of the DDV system, step 2
In the second step of calibration you have to leave the sensitivity regulator in the same position and
place a piece of iron (e.g. screw or nail) under the detectors coil. Alternative choice is to place the metal
directly on the top of the coil, like you can see in figure 9.2. Now press again the key OK and wait until
this process is also finished.
After finishing the calibration a visual signal (yellow light) should be visible on the screen. If the
headphones are connected you will also hear an acoustical signal. The DDV system is now calibrated to
work correctly on-site.

9.2.2 Adjust the discriminator
The discriminator serves to filter certain materials. So it is possible to ”exclude“ for example worthless
iron and steel objects. Or people who are hunting for treasures and gold are able to exclude other
materials with the help of this discriminator.
Illustration 9.5: Adjustment of discrimination
In figure 9.5 the regulator to adjust the discrimination is represented. This regulator can filter certain
materials. Table 2 explains the adjustment in the case of normal ground conditions1.
Adjustment Indicated materials
0 All metallic objects
3 Iron, gold, bronze, silver, aluminium
5 Gold, bronze, silver, aluminium
7 Silver, aluminium
10 Aluminium
Table 2: Standard adjustment of the discrimination
When you adjust the regulator for discrimination on gold, the detector reacts besides gold also on
bronze, silver and aluminium. To find out if there is really gold in the ground you have to follow the
following instructions:
1. Switch the discriminator on gold and start your soil examinations until you reach a place where
the detector reacts positive, which means you can hear an accustical sound signal.
2. Now switch the discriminator on silver and examine this place again. Following there will be two
possibilities:
• The detector reacts positive! The material under the ground is not gold, but could be
silver or aluminium.
• The detector does not react! There is probably golden material in the ground but also
bronze is possible.
Please consider that you always should do the ground balance, which is explained in this following
section.
1 The indications from table 2 concern the use in normal type of soil. In extreme conditions (mineralisation, salt
deposits, ... ) they can variate from this normal value.

9.2.3 Ground Balance
A correct soil reconcilation (Ground Balance) is absolutely necessary that the adjusted discrimination
can work properly. If the soil reconciliation is not done correctly the operation of the device and the
integrated discriminator cannot work properly.
In the following section you can find a list of all necessary working procedures to do a correct soil
reconciliation:
1. Power on the eXp 4000 and connect the DDV system.
2. Adjust the discriminator on the material you like, see previous section.
3. Put the device with coil approx. 10 cm above the ground.
4. Select the operating mode "Metal Detector" and confirm it.
If you hear an acoustic signal from the DDV system after these indications, then the ground balance is
not finished correctly. Repeat these steps until there is no acoustic signal from the metal detector.
The following causes can prevent a correct soil reconciliation:
• You are staying above a metalic object.
• You confirm the operating mode "Metal Detector" without holding the coil directly above the
ground.
• During the confirmation of the operating mode "Metal Detector" you are holding the coil to high
and then minimize the distance to the ground.
• You are turning the discriminator during ground balance.
Only if you are doing a correct soil reconciliation the functionality of discrimination can be
guaranteed!

In this chapter you will find possible error messages which can appear during the work with the device.
Page 72
72 Error Messages
In case you are scanning very large areas in the operating mode "Ground Scan" the stored files will also
be very large, which could fill up the internal memory completely. As soon as the free memory cell is less
than 20% the message shown in figure 10.1 will appear.
Illustration 10.1: Only a small amount of memory available
If there is no more free memory available you will see a message like in figure 10.2. You can free
memory space by transfering all stored data via software to your computer or by selecting the option
"Empty Memory" to delete all stored data without having transferred them to your computer.
Illustration 10.2: No free memory available
If message 10.3 appears the device cannot control the operating voltage. This also means it cannot warn
you in case of a low status of the battery. Also the automatic shutdown of the device may be affected. It
is adviced to let the device check from the manufacturer to avoid further damages.

Message 10.4 appears if the battery is low because of a long operating time with the device and not
enough voltage is available. You should power off the device and charge the external power supply as
soon as possible. If you continue operating with the device it could be possible that data gets lost.
Illustration 10.4: The external power supply has to be charged
Because there is a PC module integrated in the device you have to shutdown it like a normal computer.
Therefore you have to use option "Exit" from the main menu. The message like in figure 10.5 remind you
to wait until the device powered off by itself.
Illustration 10.5: Shutting down the system
If the device itself is not able to power off, a message like in figure 10.6 is shown. In this case you simply
power off your external power supply.
