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.

EXTRA UNDERGROUND DEPTH (E.U.D.)

PINPOINT

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.

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 posi-

tive 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 elimi-

nate 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 

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.

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.

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 differ-

ent 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.
