Kruzer has an internal 3700mAh Lithium Polymer battery.
Battery life is approximately 14-19 hours for the Kruzer and 9-19 hours for the multi Kruzer.
Battery life will be less in 5kHz compared to other frequencies on the multi Kruzer. Other
factors such as usage of speaker or wired/wireless headphones will also affect battery life
for each model.
Charging
Charge the Kruzer before initial use. Charging will take approximately 4-6 hours.
To charge the battery, insert one of the ends of the cable supplied with the charger to the
wired headphones / charger input socket and the other end to the charging adapter.
IMPORTANT! Do not use a different charging adapter other than the one supplied with your
device!
Operating with a Powerbank
You can also power and charge the battery with a powerbank. To do this, just insert one of
the ends of the cable supplied with the charger to the wired headphones / charger input
socket and the other end to the powerbank. Please note that you will not be able to attach
wired headphones to the device when a powerbank is attached to the device.
IMPORTANT! Do NOT use the detector underwater while connected to a power bank.
OPTIONAL WATERPROOF BATTERY PACK
You can purchase the optional battery pack and use it when the device's internal battery is
dead and you cannot charge it.
You can attach the battery pack easily to the back of the armrest as shown in the pictures.
The battery pack takes 4 AA Alkaline or rechargeable NiCd or NiMH batteries.
BATTERY INFORMATION
The battery pack does not come with the device, it is an optional accessory and it does not
include the 4 AA batteries.
Because the input socket for the wired headphones cannot be used when the optional
battery pack is attached to the device, you can attach your wired headphones to the input
socket on the battery pack.
IMPORTANT! Optional battery pack cannot be recharged and 2 optional battery packs
cannot be attached back to back to the device. When you want to charge the internal battery of the device, do not forget to disconnect the optional battery pack! Do not attempt
to attach the charging adapter to the connector on the optional battery pack. This input is
for wired headphones only!
Low Battery Level
Battery icon on the display shows the battery life status. When the charge decreases, the
bars inside the battery icon decrease, too. "Lo" message appears on the display when the
batteries are depleted.
When the optional battery is low, the device will display the low battery warning ''Lo'' on the
screen just like the internal battery. In such a case, the batteries need to be replaced or the
internal battery must be used. If you want to switch to using the internal battery, remove the
optional battery case cable and turn the device off and on again. Otherwise, the device will
continue to display the Lo battery warning.
BATTERY WARNINGS:
Do not expose the device to extreme temperatures (for example a car's trunk or glove
compartment)
Do not charge the battery in temperatures over 35° C (95° F) or below 0° C ( 32° F).
The Kruzer battery can only be replaced by Makro Detectors or its authorized service centers.
The Kruzer comes with 2.4 GHz wireless headphones. The wireless headphones are NOT
waterproof.
The wireless connection will work as long as the system box of the device is not submerged
in the water. In other words, you can use your wireless headphones while searching in
shallow water with the coil submerged underwater. Please remember though that the
wireless headphones should not contact with water.
IMPORTANT! Do not use a different charging adapter other than the one supplied with
your device to charge the wireless headphones!
In case of the system box being submerged underwater, the wireless connection will not
work. In this case, you need to purchase our optional waterproof headphones for land and

QUICK GUIDE
1) Assemble the device as per the instructions on page 1.
2) Push the on/off button to turn on the device.
3) When the device is turned on, it will start in the 2 TONE mode and 14kHz operating
frequency. You can change the mode based on ground conditions. For instance, if you
are detecting on wet beach sand, you may want to select the BEACH mode. You can also
change the frequency of the device on the multi Kruzer model. You can find more details
on search modes and frequencies further in this manual.
4) To ground balance, push and hold the GB button and pump the search coil up and down
to 3cm (1.2'') above the ground until a “beep” sound is heard.
5) You can increase the GAIN if needed. Increasing the gain will offer you greater depth.
However, if the surroundings or the ground cause excessive noise in the device, you need
to lower the gain setting.
6) Testing the device with various metals would be helpful for getting familiar with the
sounds produced by the device.
7) Based on the IDs of the metals you don't want to detect, you can adjust the DISC. setting
and ignore those metals. For instance, if you don’t want to detect ferrous metals with 00-05
ID in the 2 TONE mode, you can set the DISC. to 5.
8) If you are detecting in a very trashy area and the device is getting too many iron signals,
instead of DISC. you can use the Fe Vol. to lower or completely turn off the iron audio. This
will provide more depth.
9) You can filter out certain Target IDs using the NOTCH and enable the device to ignore
these metals during searching or to provide an iron audio for them.
10) If you wish, you can adjust the tone break points of the device with the T.BREAK feature and
change the frequency of the tones using the TONE setting.
11) You can now start searching.
12) Since your device operates with the motion principle, swing the search coil right and
left maintaining 5cm (2") distance above the ground. If the search coil does not move, the
device will not provide any audio responses even if the coil is over a metal target.
13) When a target is detected, the ID of the target and its position on the ID scale will be
displayed on the screen. The device will also produce an audio response according to the
search mode selected.
14) Upon target detection, you can pinpoint the exact location of the target by pressing and
holding the PP button. The audio volume will increase and the audio pitch will also increase
as you approach the target.
Ground balance can be performed in three ways with the Kruzer: Automatic, Manual and
Tracking.
When the GB button is pushed while performing automatic or manual ground balance,
the device will switch to the General Search (GEN) mode automatically on the background
without any indication to the user, regardless of the selected search mode.
Upon completion of ground balance, current ground balance value is shown in the Ground
Balance (GB) box on the right side of the display.
Automatic Ground Balance
Automatic ground balance is performed as follows in all search modes:
1) Find a spot where there is no metal.
2) Push and hold the GB button down (GROUND BALANCE value and “Pump Coil” warning
message will be shown on display) and start pumping the search coil up and down from
about 15-20 cm (~6''- 8'') above the ground down to 3 cm (~1'') off the ground with smooth
movements and keeping it parallel to the ground.
3) Continue until a beep, indicating the completion of ground balance, is heard. Based on
ground conditions, it usually takes about 2-4 pumps for the ground balance to be completed.
4) Upon completion of the ground balance, ground balance value is shown on the display
(GB). The device continues to ground balance and produce a beep sound as long as you keep
the GB button pushed down and pump the coil. In order to ensure that the ground balance is
proper, ground balance at least 2-3 times and check the ground balance values on the display.
In general, the difference between the values shall not be higher than 1-2 numbers.
5) If you cannot ground balance, in other words, if no beep sound is produced, it means that
either the ground is too conductive or not mineralized or there is a target right below the
search coil. In such a case, retry ground balance at a different spot. If you still cannot ground
balance, read the section titled ''Important Details Concerning Ground Balance''.
When the ground balance button is released, the device continues to operate in the GEN
mode for a short period of time and the ground balance value stays on display. This makes
it possible to manually fine tune the automatic ground balance value. Refer to the following
"Manual Ground Balance" section for further information regarding this feature. If this is
not desired, press the PP button once to return to the main screen.
NOTE: If the iSAT value is set high, the device may not auto ground balance. In such a case,
lower the iSAT value first. After ground balancing, set the iSAT back to its original position.
Page 8
GROUND BALANCE
Page 9
Manual Ground Balance
Allows you to manually modify the ground balance value. It is not preferred mostly because
it takes time. However, it is the preferred option in cases where a successful ground balance
cannot be performed using other methods or minor corrections are required to the
automatic balance.
Kruzer is designed to allow for automatic ground balancing conveniently on any type of
ground. Therefore, it is recommended to perform automatic ground balance upon start up.
However, the ground may not be suitable for automatic ground balancing in some cases
and the device cannot ground balance on such grounds (Except for the BEACH mode). For
instance, wet beach sand, soils containing alkali or salty water, trashy sites, ploughed fields,
highly mineralized grounds and grounds with very low mineralization are not suitable for
automatic ground balance. In such terrains, you can auto ground balance in the BEACH
mode and then switch to other modes or try manual ground balancing. However, manual
ground balance requires a skill which develops over time through practice.
To perform manual ground balance:
1) Find a clear spot without metals and switch the device to the GEN mode.
2) You need to listen to the sounds coming from the ground in order to perform manual
ground balance. Pump the search coil up and down from about 15-20 cm (~6''- 8'') above
the ground down to 3 cm (~1'') off the ground with smooth movements and keeping it
parallel to the ground.
If the sound gets higher when lifting off the search coil above the ground, the ground
balance value is too low, in other words, the effect from the ground is negative and the
ground balance value needs to be increased by using the ( + ) button. On the other hand,
if the sound gets higher when lowering the search coil to the ground, the ground balance
value is too high, in other words, the effect from the ground is positive and the ground
balance value needs to decreased by using the ( - ) button.
3) Push the ground balance button once and release it. The ground balance value will be
shown on the display and remain there for a moment. You can return to the ground balance
screen by pushing the ground balance button if the screen switches.
Manual ground balance functions within the
range of 0-99.80 However, each value covers
5 steps used for fine tuning within itself and
these steps are indicated as multiples of 20 in
the Ground Balance window (GB). For example,
ground balance value shown on the side is 70.80.
Press ( + ) or ( - ) to increase or decrease the ground
balance value, respectively. If the key is pressed
once at a time, the values count one by one and if
it is held down, the values will change quickly.
4) Repeat the above procedure until the sound heard from the ground is eliminated.
The sound may not be eliminated completely in some areas. In these cases, listen to the
sounds produced when moving the search coil towards and away from the ground to check
if the ground balance is correct. If there is no difference between the two sounds then the
ground balance is set properly.
GROUND BALANCE
Page 10
The device will return to the main screen automatically after a short period of time upon
completion of ground balance. To return to the main screen instantly, just press the PP
button once.
IMPORTANT! Experienced detectorists adjust the ground balance setting to a slightly positive response (weak but audible sound is produced when moving the search coil closer to
ground). This method may produce favorable results for experienced users in certain fields
where small targets are searched for.
Ground Tracking (TRACKING)
In this option, the user does not need to make any adjustments. TRACKING feature is
activated from the OPTIONS menu by switching it to 01 position. The word ''Tracking''
is displayed at the bottom of the GB window. The device updates the ground balance
automatically as long as the search coil is swung over the ground and shows the ground
balance value in the GB window. It does not provide any feedback to the user (like the
beep sound in automatic ground balance).
While tracking is active, the device can initially produce a loud signal when it detects a
different ground structure (for instance a mineral rock) or a target. In this case, swing the
search coil over the spot where the device produces the signal . If the sound remains the
same and the device shows an ID, it is possibly a target. If the sound attenuates too much
or is lost after a few swings, it means that the device has produced a signal for the different
ground structure or a stone.
NOTE: It is recommended that you use tracking in the General Search mode (GEN) and not
in the discrimination modes.
Tracking is suitable for use in areas where different soil structures are present within the
same land or in fields where mineralized rocks are scattered widely apart. If you use ground
tracking in areas where hot rocks are intensely present, the device may not be able to eliminate these highly mineralized rocks or you may miss the smaller or deeper metals.
IMPORTANT! Ensure that tracking is off during air tests. Otherwise, the device will attempt
to perform ground balance on the target and the depth will be reduced.
Ground Balance Value
Ground balance value provides information about the ground you are searching on. Some
typical ground types are as follows:
0-25 Wet salt water or wet alkali soils
25-50 Wet salt water and wet alkali soils covered with dry layers
50-70 Regular, low-quality soils
70-90 Highly magnetic soils, magnetite or maghemite and similar highly mineralized soils,
black sand.
Important Details Concerning Ground Balance
1) Upon start up, the ground balance value is set to 90. The device can perform ground
balance automatically within the range of 20-99.80 in all modes and 00-99.80 in the BEACH
mode.
2) If the ground mineralization is too low, automatic ground balance may fail to work in
GROUND BALANCE
Page 11
other modes except for the BEACH mode. In such a case, you can auto ground balance in
the BEACH mode and then switch to other modes or try manual ground balancing.
3) You can test the accuracy of the ground balance with the pinpoint mode. After ground
balancing, if you receive no sound or a weak one when you move the search coil closer to
the ground in the pinpoint mode, then the ground balance is successful. If the sound gets
louder when you move the search coil closer to the ground, then the ground balance is not
successful. In this case, simply change your location. If ground balance is not possible despite
these efforts, you should continue your search without performing ground balance.
You cannot search in the General Search (GEN) mode without ground balancing. You need to
use one of the discrimination modes and increase the DISC. value until the noise is eliminated.
4) Once the ground balance is set, it will remain satisfactory for a long time in most areas.
However, if you encounter an excavated, backfilled or geologically composite soil structure,
a ground balance should be performed again to adapt to the varying soil structure. In
addition, re-ground balancing is recommended for the multi Kruzer model if you change
the operating frequency of the device (5kHz/14kHz/19kHz) in certain ground conditions.
5) When using the optional large coil, pump the coil more slowly and do not keep it very
close to the ground.
6) In some cases where the iSAT value is set high, the device may not be able to ground
balance automatically. In such a case, first lower the iSAT and after ground balancing switch
it back to its previous position.
TARGET ID is the number produced by the metal detector based on the conductivity of the
metals and gives an idea to the user about what the target may be. Target ID is shown with
two digits on the display and ranges between 00-99.
NOTE: Keep in mind, large targets will ID higher than expected, even though they may be
of lower conductance.
In some cases, the device may produce multiple IDs for the same target. In other words, the
IDs may be jumpy. This may result from several factors. Target orientation, depth, purity of
the metal, corrosion, mineralization level of the soil etc. Even the direction of the search coil
swing may cause the device to generate multiple IDs.
In some cases, the device may fail to provide any ID. The device needs to receive a strong
and a clear signal from the target in order to provide an ID. Therefore, it may not be able to
provide an ID for targets at fringe depths or smaller targets even if the device detects them.
Keep in mind that target IDs are “probable”, in other words, estimated values and it would
not be possible to know the properties of a buried object exactly until it is dug out.
IDs of non-ferrous metals such as copper, silver, aluminum and lead are high. Target ID range
of gold is wide and may fall within the same range of metal wastes such as iron, foil, screw
caps, and pull tabs. Therefore, if you are looking for gold targets, digging out some trash
metals is expected.
TARGET ID
GROUND BALANCE
Page 12
TARGET ID
On the multi Kruzer, when the operating frequency is changed (5kHz/14kHz/19kHz), the
Target ID will change as well. This represents the ''Standard'' ID scaling of the device.
IMPORTANT! At start up, multi Kruzer will utilize the ''Normalized'' ID scale and not the
Standard ID scale. In other words, the IDs will not change upon frequency change and the
device will generate the 14kHz IDs in each frequency. However, based on ground conditions
IDs may vary for certain metals.
If you prefer to see the different IDs produced by each frequency, you need use the
''Standard'' ID scale. To switch to the standard IDs, while the device is on, push the plus
(+) and minus (-) buttons at the same time. Letters ''Sd'' will appear on the screen. If you
wish to revert back to the normalized IDs, repeat the same process and letters ''no'' will
appear on the screen.
The table showing the probable IDs for the Kruzer and the multi Kruzer models is placed
at the back of this manual. You can easily detach the page and carry it with you during
your searches.
Coins searched throughout the world are made of different metals and in different sizes in
different geographical locations and historical eras. Therefore, in order to learn the Target
IDs of the coins in a specific region, it is suggested to perform a test with the samples of
such coins, if possible.
It may take some time and experience to make best use of the Target ID feature in your
search area. Different brands and models of detectors produce different target ID numbers.
The numbers vary even more depending on target depth, ground mineralization, and
adjacent metals. But after some practice, you will quickly become comfortable with the
meanings of the Kruzer's Target IDs.
Target ID Depth
This setting is not present in the menu.
Adjusts the depth level that the device displays an ID for a detected target. It consists of 3
levels: Hi (High), In (Intermediate), Lo (Low). Factory default is set to ''In''.
The lower the ID depth level is, the higher the ID accuracy and vice versa. At the high level,
the IDs may become jumpy.
To change the ID depth level, press the PP button and the up button simultaneously. Each
time you press the up button, the ID depth level will change.
Page 13
SEARCH MODES
Kruzer has 6 search modes designed for different terrains and targets. You can navigate
between the modes easily by using the direction buttons. The selected mode name will be
framed on screen.
General Search (GEN)
Different than the other modes, this mode features a threshold tone which is continuously
heard in the background.
In this mode, the device does not discriminate targets and detects all targets (metals, mineralized rocks etc.). ID of the detected target is shown on the display (except for negative hot
rocks) and the same audio tone is provided for all targets. The audio tone increases in pitch
as the coil approaches the target. This is the typical All Metal mode found in most detectors.
Gain, threshold and iSAT settings in this mode are optimized to provide the best performance on different terrains. You can modify these settings based on ground conditions.
We recommend using the GEN mode when discrimination is not important and not using
it in heavy trash areas or areas containing many hot rocks.
2-Tone Discrimination (2 TONE)
Recommended especially for relic hunting. It produces good results particularly on clean
sites which do not contain waste metal. More depth can be obtained on sites which are
rocky or those that contain waste metals by using the DISC. and NOTCH and swinging the
search coil more slowly (one right/left pass per approximately 1 second). DISC. is set to 03
as a default value. You can modify this value according to the ID of the targets you don’t
want to detect.
In this mode, the device produces a low tone for ferrous targets with IDs between 0-15.
For targets with IDs 16-99, it produces a higher tone which increases in pitch as the coil
approaches the target. By using the T.BREAK feature, you can adjust the break points of the
target response tones on the Target ID range.
3-Tone Discrimination (3 TONE)
This is the 3-tone discrimination mode designed for coin hunting especially in trashy sites
such as parks. In this mode, the device produces a low tone for ferrous targets with 0-15 IDs, a
medium tone for gold and non-ferrous metals with IDs 16-66 and a high tone for non-ferrous
metals with IDs 67-99 such as silver, brass and copper. By using the T.BREAK feature, you can
adjust the break points of the target response tones on the Target ID range.
4-Tone Discrimination (4 TONE)
4-tone discrimination mode designed for coin hunting in low-medium mineralization. Due to
its high gain and depth, this mode is a bit noisier than the other modes. Noise will be more in
the air versus in the ground. Take this fact into consideration when adjusting the gain level.
In this mode, the device produces a low tone for ferrous targets with 0-15 IDs, a medium tone
for gold and non-ferrous metals with IDs 16-30, a medium-high tone for metals with 31-66
IDs, and a high tone for non-ferrous metals with IDs 67-99. By using the T.BREAK feature, you
can adjust the break points of the target response tones on the Target ID range.
Page 14
BEACH MODE (BEACH)
This is a special mode of the Kruzer developed for conductive grounds (salty wet sand beach,
grounds with alkali soil etc.). The feature of this mode presents the ability to ignore iron
and similar targets in this group and to be able to perform ground balance on any type of
ground. While the device performs ground balance in the range of 20-99.80 automatically in
the other discrimination modes, the device ground balances in the range of 0-99.80 in this
mode. This enables easier ground balancing on conductive grounds where normally ground
balance cannot be performed at all or performed with difficulty.
In this mode, the device produces a low tone for ferrous targets with IDs between 0-15.
For targets with IDs 16-99, it produces a higher tone which increases in pitch as the coil
approaches the target. By using the T.BREAK feature, you can adjust the break points of the
target response tones on the Target ID range.
Different than the other modes, the DISC. is set to 15 as a default value in this mode in order
to ignore ferrous metals or ground noise.
Salt water and alkali grounds are significantly conductive due to high ionization and cause
effects similar to that of iron in detectors. These effects may make it impossible to search
for metals with a standard detector. Existence of an iron elimination feature in a detector
can improve the situation but may not be sufficient.
Kruzer's BEACH mode eliminates such effects and ground noise. Aspects to be taken into
consideration while searching on conductive grounds are explained in more detail in the
section titled Detection on the Beach and Underwater (page 27).
Deep Mode (DEEP)
Recommended especially for relic hunting, this mode is the deepest mode of the device.
Therefore, it may run relatively noisier. Noise will be more in the air versus in the ground. Take
this fact into consideration when adjusting the gain level. While searching in this mode, a
slower swing speed is required.
The discrimination ability of the DEEP mode is relatively less compared to the other modes.
Hence, its performance may vary on trashy sites versus clean ones.
In this mode, the device produces a low tone for ferrous targets with IDs between 0-15. For
gold and non-ferrous targets with IDs 16-99, it produces a higher tone which increases in
pitch as the coil approaches the target. By using the T.BREAK feature, you can adjust the
break points of the target response tones on the Target ID range.
SEARCH MODES
Page 15
SETTINGS
Push the SETTINGS button to access the basic settings. You can navigate the basic settings
with the up and down buttons. The value of the selected setting will be displayed on
screen. You can change the value using the plus (+) and minus (-) buttons. If the up/down
and +/- buttons are held down, the options and values will change rapidly.
To exit the settings, press the SETTINGS or the PP button once. Settings will time out in
approximately 8 seconds and the device will revert back to the modes window.
NOTE: Certain settings are mode specific and thus cannot be selected in other modes.
GAIN
Gain is the depth setting of the device. It is also used to eliminate the ambient electromagnetic signals from the surrounding environment and noise signals transmitted from ground.
NOTE: To obtain maximum depth performance, to eliminate the noise caused by electromagnetic interference, try shifting the frequency first.
Frequency shift is done with the FREQ. option in the Kruzer and with a combination of
buttons in the multi Kruzer (see pages 21-22). In the multi Kruzer, when the frequency
shifting is not sufficient for eliminating noise, you can also change the operating frequency
(5kHz/14kHz/19kHz) of the device.
Gain setting range is 01-99 and pre-defined for each mode. All modes start at default
settings. They can be manually modified when necessary. Gain adjustment applies to the
selected mode; the modified setting does not affect the gain setting of the other modes.
NOTE: If the ground is highly mineralized causing the device to overload, decrease the gain
until the ''Overload'' message disappears from the screen.
Gain in General Search Mode (GEN):
In the GEN mode, gain setting causes an increase or decrease in the popping sounds and false
signals. Gain setting is a personal preference. However, It is important to set the gain setting
to the highest level possible where no major popping sounds are heard to avoid missing
smaller and deeper targets. For example; if the noise level is suitable for searching and is the
same at gain levels 40 and 70, then 70 should be preferred. Using the factory default levels
will be a good starting point until you get familiar and experienced with the device.
Gain in Discrimination Modes:
Since the threshold setting is not available in the discrimination modes, you can increase
the depth of the device or ensure noise-free operation on different grounds only by using
the GAIN setting.
In order to adjust the gain in the discrimination modes, first ground balance while the gain
is at its default setting. After ground balance is completed, hold the search coil stationary or
swing over the ground at search height. Reduce the gain if the device receives noise. If not
(ensure that the DISC. is also at its default settings when checking this), increase the gain
gradually until there is no popping sound. If the device starts to receive noise during
searching, reduce the gain gradually.
NOTE: Kruzer is a high gain device and some of the search modes will run relatively noisy
(DEEP and 4 TONE) compared to other modes so as to provide the best depth performance.
However, due to the design characteristics of these modes, the noise will be heard more if
Page 16
the coil is in free air than sweeping the coil on the ground. Please keep this factor in mind
while adjusting the gain.
Discrimination (DISC.)
Disc. is the ability of the device to ignore all metals below a certain Target ID. In the DISC.
process, the filtered ID range is shown with lines on the ID scale and every 2 consecutive IDs
are represented with 1 line. For example, if you set the Disc. to 30, 15 lines will be shown
between the 0-30 ID range on the scale and the device will not produce an audio response
for any metals with IDs between 0-30.
DISC. setting is disabled for GEN mode only. For all other modes, the factory default value
will be displayed on screen at start up.
In order to change the DISC. value, select the DISC. option from the SETTINGS and decrease
or increase the value using the plus (+) or minus (-) buttons. Please remember that certain
targets, other than the ones you want to ignore, may also be missed or their signals may
become weaker when using the DISC. setting.
In the case of receiving multiple IDs for the same target - let's say 35 and 55 - due to the orientation of the target or the composition of the metal itself, if you set the DISC. to 40, because
35 will fall in the filtered range, the signal strength as well as the depth may diminish.
NOTE: DISC. setting works inversely proportional to depth up to level 15 in all modes. In
other words, as the DISC. is increased up to 15, stability will increase but depth will be
reduced and vice versa. Above 15 though, both depth and noise will increase.
NOTCH
NOTCH is the ability of the device to discriminate single or multiple Target IDs by not
emitting an audio response for them or giving a low iron tone (please refer to iron tone in
notch).
Although NOTCH may seem similar to DISC. at first glance, these two settings have different
functions. While the DISC. filters out all IDs between 0 and the set value, the NOTCH filters
IDs individually.
With the NOTCH you can reject a single ID or multiple IDs at the same time. This process
does not affect any IDs below or above the selected IDs. For example, you can filter out IDs
between 31-35 as well as 50 simultaneously.
How To Use The NOTCH Setting
When NOTCH is selected from the SETTINGS, first, the current DISC. value will be displayed
on screen and discriminated ID range will be shown on the ID scale with lines. For example,
if the DISC. is set to 15, when you select NOTCH, number 16 will be displayed on screen
corresponding to 8 lines on the ID scale (every 2 consecutive IDs are represented with 1
line). NOTCH cannot be used within the DISC. range. In other words, if the DISC. is set to 15,
NOTCH can only be applied to IDs 16 or higher. If you want to NOTCH IDs 15 or below, first
you need to change the DISC. value.
NOTCH rejects or accepts IDs with the help of the cursor in the middle of the screen. To
move the cursor on the scale, plus (+) and minus (-) buttons are used. The cursor blinks
while it is moving on the scale. When you are on the first ID that you want to reject, press
SETTINGS
Page 17
the SELECT button once. This ID is now rejected and it is shown on the screen with a line. If
you want to reject multiple IDs, continue to press the plus (+) or minus (-) button. If
non-consecutive IDs are to be rejected, push the SELECT button once to have the cursor
blink for navigation on the scale and repeat the process above. The cursor will appear
where you left it the next time you use the NOTCH.
To give an example; let's say you want to reject IDs between 20-25 and the cursor is at 10.
Press the plus (+) button until you reach number 20. Then push the SELECT button once.
Number 20 will be marked with a line. When you reach number 25 using the (+) button
again, IDs between 20-25 will be filtered out and they will be shown on the ID scale with 4
lines (every 2 consecutive IDs are represented with 1 line).
To accept back the filtered IDs, select NOTCH from SETTINGS. The cursor will appear where
you last left it. Using the plus (+) or the minus (-) button, select the ID you want to accept
and push the SELECT button. Then, using the plus (+) or minus (-) button again, unfilter the
IDs back in. 1 line will be erased for every 2 consecutive IDs accepted.
Iron Tone in Notch Setting:
This will enable you to get a low iron tone for your notched out target IDs instead of
silencing them. To use this feature, first select Fe VOL. from the SETTINGS and using the
plus (+) button select the iron tone volume between n1-n5. n5 is the maximum level and
the iron volume will be reduced as you go down but it cannot be silenced completely.
NOTCH adjustment applies to the selected search mode only. The change does not affect
the other modes.
IMPORTANT! In the multi Kruzer, if you are using the Standard ID scale and you change the
operating frequency of the device, you may need to re-adjust the NOTCH values according
to the IDs you will get in the new frequency.
Iron Volume (Fe VOL.)
It adjusts or turns off the volume of the low iron tone. It can be adjusted between 0-5 or
n1-n5.
0-5: 5 is the maximum level. As you lower it, the audio response volume the device
produces for ferrous metals will decrease. At 0 level, the iron audio will be silenced. In
other words, the device will detect ferrous targets, the Target ID will be displayed on the
screen but the device will not produce any audio response.
n1-n5: This will enable you to get a low iron tone for your notched out target IDs instead of
silencing them. n5 is the maximum level and the iron volume will be reduced as you go
down but it cannot be silenced completely.
Fe VOL. adjustment applies to the selected search mode only. The change does not affect
the other modes.
Tone Break (T.BREAK)
It is used to adjust the break points of the target response tones on the Target ID range.
Default Tone Break points in the Kruzer will vary according to the search mode. By using the
Tone Break feature, for each metal group (Fe, Gold/Non-Fe, Non-Fe) you can change the
point where the low tone changes into the higher tone.
SETTINGS
Page 18
To use the Tone Break feature, first select T.BREAK from SETTINGS . The names of the metal
groups mentioned above will appear at the bottom of the screen. The Tone Break point of
the metal group will be shown on the screen numerically while the cursor at the top will
point to it on the ID scale. In some modes, there are 2 tone break points and in some there
are 3. To select the metal group, just push the SELECT button. Selection will be framed. To
change the value of the break point, plus (+) or minus (-) button is used.
To give an example for the above explanation; let's say you are in the 3 TONE mode and you
want to change the Tone Break points. First, select T.BREAK from SETTINGS. Fe and
Gold/Non-Fe will appear at the bottom of the screen and Fe will be framed. The default
value of 15 will also be displayed on the screen. Using the plus (+) or the minus (-) button
change this number to any value you want. Let's say you increased it to 40. Then, push the
SELECT button once to select the Gold/Non-Fe. Let's say you decreased the default value of
66 to 50. In this case, the device will produce a low iron tone for all metals with IDs equal to
or less than 40, a medium tone for metals with IDs 41-50 and a high tone for metals with IDs
greater than 50 (If you have also adjusted the audio tones (TONE), the selected frequency
will apply to the new ID ranges).
Tone Break adjustment applies to the selected search mode only. The change does not
affect the other modes.
IMPORTANT! If you are using the Standard ID scale in the multi Kruzer and you change the
operating frequency of the device, you may need to re-adjust the Tone Break points
according to the IDs you will get in the new frequency.
TONE
Allows you to change the target audio response tones and the threshold sound according
to your preference. For each metal group (Fe, Gold/Non-Fe, Non-Fe) the frequency can be
adjusted between 150 Hz (15) and 700 Hz (70).
When TONE is selected from the SETTINGS, names of the metal groups mentioned above
will appear at the bottom of the screen and the selected one will be framed. To select
another group, just press the SELECT button. Then use the plus (+) or the minus (-) button
to change the audio frequency.
NOTE: If you want to change the frequency of the 4th tone in the 4 TONE mode, while Non-Fe
is selected, press the SELECT button once. The frame will disappear and the audio frequency
of the 4th tone will appear on the screen. use the (+) or the (-) button to change it.
TONE adjustment applies to the selected search mode only. The change does not affect the
other modes.
Threshold (Thresh.)
In the General Search Mode (GEN), search is performed with a continuous humming sound in
the background, also referred to as the threshold sound. The loudness of this hum directly
impacts the detection depth of smaller and deeper targets and it is adjusted by the threshold
(Thresh.) setting. If the threshold is set too high, a weak target signal may not be heard. On
the contrary, if the threshold is too low, you give up the depth advantage this setting offers.
In other words, weak signals of smaller or deeper targets may be missed. It is recommended
for average users to leave this setting at its default value and for experienced users to adjust
to the highest level where they can still hear the weak target signals.
SETTINGS
Page 19
Threshold level is directly related to the Gain and iSAT settings. Please be sure to read the
related sections of the manual carefully.
iSAT (Intelligent Self-Adjusting Threshold)
iSAT in General Search Mode (GEN)
For the General Search Mode (GEN) to perform accurately, a stable threshold sound is necessary. You cannot search in the General Search Mode without ground balancing. Changes
that occur in the soil structure and mineralization levels after ground balancing, may cause
a rise or fall in the background hum and disrupt the threshold's stability which will result in
false signals and thus missing signals of small metals. iSAT adjusts the speed that the device
recovers its threshold hum and eliminates the negative effects of mineralized soils.
Increasing the iSAT in high mineralization will enable a more stable operation by avoiding
false signals. This, however, may cause some loss in depth and it is normal.
NOTE: In high mineralization, if you receive too many false signals without disruption in the
threshold hum, lower the gain first before increasing the iSAT. If the false signals continue,
set the gain back to its original value and increase the iSAT.
If the mineralization is low, you can decrease the iSAT and sweep the coil more slowly for a
deeper detection.
iSAT consists of 10 levels. The device will start at level 6. It is recommended that iSAT should
be increased in high-mineralization and decreased in low mineralization.
iSAT in Discrimination Modes
It is used to eliminate false signals caused by ground noise or hot rocks when searching in
discrimination modes and the available range is between 00-10. Its factory default value is
set to (1). You can change the value using the plus (+) and minus (-) buttons.
If the device receives a lot of false signals due to highly mineralized soil or hot rocks in the
discrimination modes, first re-ground balance. If the false signals continue, lower the GAIN
and check again. In case the false signals still exist, try increasing the DISC. value. Regardless
of all these, if the false signals still exist, first change the GAIN and DISC. values back to their
previous levels. Then, increase the iSAT level until the false signals are eliminated.
At the maximum level of iSAT, false signals will disappear or will be minimized. However, in
some cases, increasing the iSAT will result in loss of depth for certain metals such as
copper.
NOTE: When detecting in 19kHz, on wet or highly mineralized ground, in order not to miss
smaller high conductive metals (silver, copper etc.) it is recommended not to increase the
iSAT level too high.
NOTE: iSAT value ranges between 00-10. The factory default is 01. At ''0'', the iSAT feature
will be inactive. If the ground is not highly mineralized or does not contain many hot rocks,
setting the iSAT to ''0'' is recommended.
SETTINGS
Page 20
Volume
This control allows you to increase or decrease the device's volume based on your preference
and environmental conditions. Volume level can be adjusted from 0 to 10. When you turn off
and on the device, it will start with the last volume level you chose. This setting is common to
all modes; changes will take effect in all modes.
Because the volume level affects power consumption, we recommend you not to increase
it more than necessary.
Brightness (BRIGHT.)
It enables you to adjust display backlight level according to your personal preference. It
ranges between 0-5 and C1-C5. At 0 level, the backlight is off. When set between 1-5, it
lights up only for a short period of time when a target is detected or while navigating the
menu and then it goes off. At C1-C5 levels, it will be continuously lit. The continuous operation of the backlight will affect power consumption, which is not recommended.
The backlight setting is restored to the final saved setting when the device is turned off and
on again. This setting is common in all modes; change made in any mode also applies to the
other modes.
Vibration (VIBRATE)
This feature provides feedback to the user by producing a vibration effect when a target is
detected. It can be used independently or together with the audio response. When audio
response is disabled, all feedbacks are provided to the user as vibration only during target
detection.
Vibration setting is adjusted within the range of 00-05. When it is switched to 0, vibration
feature is completely disabled. If the vibration is at 01 level, the device provides long vibration signals and at 05 it provides short vibration signals. The magnitude of the vibration
effect can vary according to the depth of the target and the swinging speed. This setting is
common in all search modes; change made in any mode also applies to the other modes.
Vibration may not be felt in the General Search mode (GEN) with weak signals; it will be felt
as the signal gets stronger. In other words, vibration does not start at the depth where the
audio tones are heard but at a lesser depth. Therefore, if you are detecting with vibration
only and audio tones are off, you can miss weaker and deeper signals.
Vibration speed is constant in the pinpoint mode and cannot be adjusted. Vibration is off at
0 position. 01-05 values provide the same level of vibration in the pinpoint mode. When
vibration is used in the pinpoint mode, vibration speed increases as the target is
approached and it reaches the maximum level over the center of the target.
The vibration setting is restored to the final saved setting when the device is turned off and
on again. This setting is common in all modes; change made in any mode also applies to the
other modes.
Tracking (TRACKING)
When tracking is active (01 position), the device continuously tracks the changing ground
structures and automatically reconfigures the ground balance setting. The invisible changes
in ground affect the detection depth as well as the discrimination ability of the device so it
is possible to operate the device at higher performance using this feature under suitable
OPTIONS

ground conditions. Please refer to page 10 for more information on Tracking.
When tracking is activated, ''Tracking'' will be displayed at the bottom of the GB window.
NOTE: Tracking is recommended to be used in the GEN mode only.
Frequency (FREQ.)
This setting has different functions in the Kruzer and the multi Kruzer. In the Kruzer, it is
used to shift the frequency and in the multi Kruzer it is used to change the operating
frequency of the device.
FREQ. Setting in the Kruzer - Frequency Shift
It is used to eliminate the electromagnetic interference that the device receives from
another detector which operates in the same frequency range nearby or from the
surroundings. If too much noise is received when the search coil is lifted in the air, this may
be caused by the local electromagnetic signals or excessive gain settings.
To eliminate the noise caused by electromagnetic interference, try shifting the frequency
first (FREQ.) before lowering the gain to obtain maximum depth performance . Frequency
shift consists of 5 steps. Default setting is F3 which is the central frequency. You can shift the
frequency between F1-F5 using the plus (+) and the minus (-) buttons.
IMPORTANT! Frequency shift may impair performance. Therefore, it is suggested that you
do not shift the frequency unless it is necessary.
FREQ. Setting in the multi Kruzer - Changing the frequency
Multi Kruzer offers 3 operating frequencies — 5kHz, 14kHz and 19kHz— to suit different
target and soil types.
Based on the frequency selected, the detector's detection performance for different types
of targets will vary. The list below includes, but are not limited to, different types of targets
that correspond to each frequency:
5kHz: Large ferrous and non-ferrous objects
High conductive coins
Medium or relatively small targets in non-mineralized ground without iron trash
Ferrous masses and militaria
14kHz: General use
Small coins
Different size coins in medium-highly mineralized ground
19kHz: Small coins with different conductivities and thin large coins
Gold coins, rings, small jewelry , sheet iron, foil
Small targets in iron trash
To change the operating frequency of the device, press the OPTIONS button first. After
selecting the FREQ. option, change the frequency using the plus (+) and minus (-) buttons.
You will hear the sound of the relay circuit; this is normal. At the same time, lines will start
rotating in the middle of the screen and they will stop when the new frequency is active.
OPTIONS
Page 22
Shifting the Frequency in the multi Kruzer:
Just like in the Kruzer, it is used to eliminate the electromagnetic interference that the
device receives from another detector which operates in the same frequency range nearby
or from the surroundings.
To shift the frequency, first select FREQ. from OPTIONS and then press SELECT once.
Frequency shift consists of 5 steps. Default setting is F3 which is the central frequency. You
can shift the frequency between F1-F5 using the plus (+) and the minus (-) buttons.
Factory Default /Save (FD/SAVE)
With the FD/SAVE feature of the Kruzer, you can save your settings or restore factory
defaults. Save function saves all settings except for the ground balance and tracking. The
device starts in the last mode where the save function was performed.
To save your settings, select FD/SAVE on screen. Two dashes (--) will be displayed on screen.
Push the right button. When ''SA'' is displayed, press the SELECT button once. You will see
lines rotating in the middle of the screen. When the saving is completed, the lines will stop
rotating and the SA text will disappear.
To go back to factory defaults, select FD/Save on screen. Two dashes (--) will be displayed on
screen. Push the left button. When ''Fd'' is displayed, press the SELECT button once. You will
see lines rotating in the GB window on the right side. When the process is completed, the
lines will stop rotating and the Fd text will disappear.
Wireless Connection (WIRELESS)
It is used to turn on and off the wireless headphones connection and to change the channel.
After choosing the WIRELESS option, you can change the channels between 00-19 or you
can completely turn the wireless connection off by choosing the oF (off) position.

EXTRA UNDERGROUND DEPTH (E.U.D.)
PINPOINT
The target IDs of certain metals (such as gold) in high mineralization and under hot rocks or
at fringe depths may be reflected differently on the device than what they really are.
Based on the DISC. setting, you may experience a depth loss for such metals or the device
may not detect these metals at all.
The E.U.D feature of the Kruzer enables you to detect such metals deeper utilizing a different tone than the other tones of the device. When using the E.U.D, the device does not
discriminate metals and it provides the same tone for all targets.
You can use the E.U.D feature of the device 2 ways: Instantly or continuously. To use the
feature instantly, you must keep the SELECT button pushed down, and to use it continuously
you must double click the SELECT button. In both cases, the frame around the selected
search mode will keep on blinking.
E.U.D will not work in the GEN and BEACH modes. If you are using the E.U.D constantly,
unless you turn it off, the feature will be active even if you change the search mode.
NOTE: Because this feature enables the device to detect some targets that are normally
masked by ground conditions and thus are undetectable, it is possible to dig more
ferrous targets when using this feature.
Pinpoint is to find the center or the exact location of a detected target.
Kruzer is a motion detector. In other words, you are required to move the search coil over
the target or the target over the search coil in order for the device to detect the target. The
pinpoint mode is a non-motion mode. The device continues to give a signal when the
search coil is kept stationary over the target.
Ground balance should be performed properly in order to ensure precise pinpointing. It is
recommended to perform ground balance again before performing pinpoint operation on
changing ground structures.
In the pinpoint mode, estimated target depth is shown on the display. In the pinpoint
mode, the signal tone increases in pitch and volume as the search coil approaches the
target. In this mode, the device does not discriminate or give target IDs. If the device is in
the vibration mode, the speed of vibration will increase as you get closer to the center of
target.
To perform pinpoint:
1) After a target is detected, move the search coil aside where there is no target response
and push the PP button.
2) Keep the button pressed down and bring the search coil closer to the target slowly and
parallel to the ground.
3) Signal sound becomes stronger and changes in pitch while getting closer to the target
center and also the number indicating target depth on the display decreases.
4) Mark the position which provides the loudest sound using a tool or your foot.
Page 24
TARGET DEPTH
The device provides an estimated target depth according to the signal strength both
during detection and in the pinpoint mode.
Depth Indicator: It shows the target's proximity to the surface in 5 levels during detection.
Because each mode of the Kruzer has different depth, the depth indicator will display a
different depth level for the same target in different modes.
In the pinpoint mode, estimated target depth is shown on the display in cms (or inches please see below for details) while getting closer to the target.
Depth detection is adjusted presuming that the target is a 2.5cm (1'') coin. Actual depth
varies according to the size of the target. For instance, the detector will indicate more
depth for a target smaller than a 2.5cm (1'') coin and less depth for a larger target. In
reality, pinpoint procedure is not intended for depth determination but exact location
determination. Therefore, it is recommended that the depth indicator on the display is
used for determining the proximity to the target.
IMPORTANT! If you want the target depth to be displayed in inches instead of cms please
do the following: While the device is off, press and hold the SELECT and OPTIONS buttons
simultaneously and turn the device on. ''In'' will be displayed. To switch back to cms, you
need to turn the device off and then repeat the above procedure. While the device is
initializing, ''SI'' will be displayed.
LARGE OR NEAR-SURFACE TARGETS
Targets which are near the surface may give multiple different signals to the device. If you
suspect a target near the surface, lift the search coil and swing it more slowly until a single
signal is received. Also, if there is a large target near the surface it may cause an overload in
the search coil and the device starts to generate a continuous sound which resembles a
siren. “Overload” message is shown on the display simultaneously. In such a case, lift the
search coil up until the message disappears.
FALSE SIGNALS AND REASONS
Sometimes, the device may produce signals which are similar to a target signal although
no metal target is present. There are various reasons for the false signals received by the
5) Repeat the above procedure by changing your direction 90°. Actions to be performed
from a couple of different directions will narrow the target area and provide you with the
most exact details of the target location.
device. The most common ones are ground mineralization or rocks with high mineral
content, surrounding electromagnetic signals, operation of another nearby detector,
rusted or corroded iron or foil in the soil, gain or threshold values set too high.
Surrounding electromagnetic signals can be eliminated by reducing the gain. If another
detector is operating nearby, you may attempt to shift the frequency or perform your
search at a distance where no interference occurs. If these do not improve the situation, in
the multi Kruzer, you may try changing the operating frequency (5kHz/14kHz/19kHz) of
the device. For ground mineralization or rocks with high mineral content, and gain and
threshold set too high, please read the related sections.
MAGNETIC MINERALIZATION INDICATOR
The Magnetic Mineralization Indicator consists of 5 levels. The indicator bars do not rise at
low mineral levels during search and at start up. In areas where the magnetic mineral level
is high, the indicator bars will rise according to the intensity. This measurement can be
summarized as the level of magnetic property and intensity of the ground.
This measurement is important from two aspects. First, on grounds with high magnetic
mineralization, search depth is low and users should be aware of this fact. Second,
magnetic mineralization is a property which is particularly seen with mineralized rocks
and this measurement plays an important role for the device to eliminate the false signals
produced by these rocks.
ROCKS AND SEARCHING IN ROCKY TERRAINS (GENERAL AND DISCRIMINATION MODES)
Challenging ground conditions arise especially when conductivity and magnetic properties
of the ground are too intense. Operation of the device over such ground is made possible by
selecting the best operating mode and frequency (multi Kruzer) as well as using proper
ground balance, gain, iSAT and threshold settings.
Stones and rocks or cavities inside the ground are as important as the ground itself in
regards to the search and target detection quality.
Soil and rocks have two different properties just like the targets you are searching for. One
of them is the intensity and the other one is the conductivity - magnetic permeability ratio
and these two properties are independent from each other. In this manual, the conductivity
- magnetic permeability ratio will be referred to as ID in short. High magnetic permeability,
low conductivity results in low ID. Soil or rocks can be highly permeable and have low or
high IDs as well. If the conductivity increases relative to magnetic permeability then the ID
will also increase.
Hot rocks are classified as negative or positive based on their ID being low or high in
comparison to the ID of the soil they are in. One or both of the types may be present in a
field. The negative and positive effects mentioned here will only be valid if ground balancing
is properly done on the existing ground. Otherwise, soil itself will not act differently from hot
rocks in terms of ID. In ''TRACKING'' however, conditions will differ. Therefore, the effects of
rocks in tracking will be discussed separately. Here we are referring to a proper ground
balance without tracking.
Positive rocks act just like metal and produce a metal sound. In the General Search Mode
(GEN) they produce a “zip zip” sound when the search coil is moved over them. If the signal
is strong enough, the device may produce an ID for these rocks. Negative rocks in the
Page 25
Page 26
General Search mode, produce a long “boing” sound when the search coil is moved over
them. The device does not give an ID for these rocks even if the signal is strong.
Positive rocks provide a typical metal sound in discrimination modes. Negative rocks do not
provide a sound in discrimination modes (except for rare cases of false signals).
At higher settings of iSAT, there will be no change in the sounds of positive or negative hot
rocks. As the iSAT value is decreased, the sound of positive hot rocks will remain the same
but the negative hot rocks may give a thinner beep sound instead of the boing sound.
Therefore, you can make a decision by listening to the audio responses produced by the
device in the field. If you receive a metal sound, it means that you either detected a positive
rock or a piece of metal. If you receive a strong signal and a stable ID, you can distinguish if
the detected target is a rock or metal by checking the ID. However, remember that weak
signals may produce different IDs and metals under rocks may produce different metal
signals. Therefore, the most appropriate action is to dig up when a metal signal is received.
If you are operating with discrimination modes and you know the ID of the surrounding
rocks, you can use the DISC. setting to eliminate the rocks. However, this may not be
sufficient to avoid all rock signals. The device may still receive signals from rocks because
soil and rocks together will form a combined effect and generate a different ID than those
of rocks.
TRACKING AND EFFECTS OF ROCKS
When the tracking is active, the device may give an audio response and ID when it passes
over a hot rock because the effect of the rock will be different than the ground's. If you
swing the search coil over the rock, tracking will automatically adjust the setting and the
audio response/ID will either disappear or diminish significantly. Because there is a slight
delay in tracking, you may hear a strong signal at the first one or two swings until the
setting is adjusted. Then the sound will get weaker and disappear. This will not happen with
metal targets because metals will prevent the device from ground balancing. Therefore, in
tracking, if you are getting a constant signal over a target after repeated swings, there is a
high possibility that the target is a metal. Moving from over a rock back to soil, the device
may give signals to the ground for a few swings until the ground balance setting is updated
again. This is normal and should not mislead you.
Tracking is not recommended to eliminate rocks under normal conditions. It is recommended for use in areas with changing soil types.
METALS UNDER ROCKS
Kruzer increases the possibility of detecting metal targets under mineralized rocks
through the proper adjustment of your settings. The combined effect created by the rock
and metal together is lower than the effect that the metal creates by itself and the
displayed ID will be different than the metal's expected ID. The displayed ID is formed by
the combination of rock and metal together and gets closer to the ID of the rock if the size
of the metal is smaller in relation to the rock. Keep in mind that metals under hot rocks will
never appear with their own metal ID. For instance, a gold piece under a brick may produce
an iron tone and ID.
Remember this very simple principle as it will save you lots of time: “If the target you detect
is not a stone, it can be metal”.
Page 27
The key to detecting targets under mineralized rocks, particularly when positive rocks are in
question, is the knowledge of the maximum ID value produced by the surrounding positive
rocks. If you are performing a search in the General Search mode (GEN), monitor the ID
produced by the device. If the ID provided by your device is close to the rock and iron zone,
it is quite possible that you detected a target under the rock. In the case of using DISC. in the
GEN mode, all rocks below the Disc. level will produce a low iron tone and all above will
produce a higher tone.
If you filter off the rocks with a correctly adjusted DISC. setting in discrimination modes, you
can hear the signal of the target under the rock if the target signal has a slightly greater effect
than the filtered ID. The important thing here is that if you detect a target and dig out a rock,
you should note the ID you got before digging and use it as the Disc. value the next time.
For instance; the hot rocks in your search field tend to give IDs around 00-01. In this case,
you should set the DISC. to maximum 02. This way you can eliminate rocks and receive the
signals of metals underneath. If you set the Disc. too high unnecessarily, you will lose metals
along with rocks.
If the hot rocks in your search area tend to give high IDs, then the chances of missing the
signals of small metals underneath will be high as well.
IMPORTANT! When searching in fields with hot rocks, using the E.U.D feature (page 23) is
recommended to avoid missing metals under hot rocks.
SEARCHING ON THE BEACH AND UNDERWATER
Kruzer is a waterproof metal detector. This provides convenient detection underwater and
on the beach.
As explained before, salt water and alkali grounds are significantly conductive and cause
effects similar to iron in detectors. Kruzer's BEACH mode is specially designed for such
conditions. You can perform your search easily using the BEACH mode without requiring
any special settings.
BEACH mode is ideal for salty wet beach sand. You can use the other modes while
performing search over dry beach sand.
You should consider the following while performing search over wet beach sand or
underwater:
1) When you swing the search coil over the holes you dig in wet beach sand, you can receive
metal signals, this is a normal condition.
2) The search coil may give false signals when going into and coming out of the water so
please try to keep the coil either in or out of the water.
Pay attention to the items below after using the device especially under salty water:
1. Wash the system box, shaft and the coil with tap water and be sure no salt water is left
in the connectors.
2. Do not use any chemicals for cleaning and/or for any other purposes.
3. Wipe the screen and the shaft dry with a soft, non-scratch cloth.

MESSAGES
Kruzer has software update capability. All software updates made after the device is
released to the market will be announced on the product's web page along with updating
instructions.
System Version Information:
To see the software version of the Kruzer's system card and LCD, while the device is OFF,
press the plus (+) and minus (-) buttons simultaneously and turn the unit on. Continue to
hold the buttons depressed until you can read the software version. The major version will
be shown in the Target ID section and the minor version in the GB window.
SOFTWARE UPDATE
Warning messages are shown at the bottom of the display. Messages that may appear are
as follows:
Overload
It appears on the display simultaneously with the overload alarm. This happens when the
search coil encounters a near surface or a very large object. The device reverts back to
normal operation if you lift the coil up. If the alarm and the message continue along a long
line, you may be over a long metal such as a pipe.
In case of high mineralization, the device may overload. If the cause of overloading is not a
large metal, it may be the ground itself and this situation may be overcome by lowering the
gain.
Pump Coil
This message appears when the GB button is pressed for ground balancing. It does not
indicate any error or problem. It only indicates what should be done.
Check Coil
It indicates an interruption in the search coil transmitter signal. The search coil connector
may be unattached, loose or disconnected. If you own another detector with the same coil
connector, please be sure that you have not attached the wrong coil by mistake. If none of
the above exists, the search coil or its cable may have a defect. If the issue continues when
you change the search coil, there may be an issue in the coil control circuit.
