5 is the maximum level. A s you lower it , the audio response volume the device pr oduces for
ferrous metals will decr ease. At 0 lev el, the iron audio will be silenc ed. In other words , the
device will detect ferrous tar gets, the T arget ID will be displayed on the screen but the
device will not produce an y audio response.
T one Break ( T .BREAK)
It is ac tiv e in the MICRO mode only . I t is used to adjust the br eak point of the ferrous
target response tone between 00-66 on the T arget ID range .
T o use the T one Break f eature , first select T .BREAK from SET TINGS . The ferrous tone br eak
value of 40 will be displayed . Y ou can adjust this value between 00-66 by using the plus (+)
and minus (-) buttons.
Let's say , you changed this value to 50. In this case, the devic e will produce a low ir on tone
for all metals with IDs equal to or less than 50.
T ONE
This featur e is selec table in all modes ex cept for the MICRO mode . Allows you t o change the
frequency of the target audio response tone and the thr eshold sound according to y our
prefer ence. The frequency can be adjusted between 150 Hz (15) and 700 Hz (70).
T ONE adjustment applies to the selected search mode only . The change does not affect the
other modes.
Brightness (BRIGHT .)
It enables you to adjust display backlight level accor ding to your personal pref erence. It
ranges between 0-5 and C1-C5. At 0 level, the backlight is off . When set bet w een 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 c ontinuously lit. The continuous
operation of the backlight will affect power consumption, which is not r ecommended.
The backlight setting is restored t o 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.
Fr equency (FREQ.)
It is used to eliminate the electromagnetic interference that the devic e receives from
another detector which operates in the same frequency range nearby or from the
surroundings. If too much noise is r eceived when the search c oil is lifted in the air , this may
be caused by the local electromagnetic signals or ex cessive gain settings .
T o eliminate the noise caused b y electromagnetic interference, try shifting the frequency
first (FREQ .) befor e lowering the gain to obtain maximum depth performance . F requency
shift consists of 5 steps. Default setting is F3 which is the centr al frequency . Y ou can shift the
frequency between F1-F5 using the plus (+) and the minus (-) buttons.
IMPORT ANT! F requenc y shift may impair performance. Therefor e, it is suggested that y ou
do not shift the frequency unless it is necessar y .
19
While the device is in detection mode, meaning when the cursor is poin ting at MODE, press
the SET TINGS/OPTIONS button once to access the settings . Y ou can navigate the settings
with the up and down buttons. The value of the selected setting will be displayed on
screen. Y ou can change the value using the plus (+) and minus (-) buttons. If the up/down
and +/- buttons are held down, the options and v alues will change rapidly .
T o exit the settings , press the SET TINGS/OPTIONS button twice or the PP button once.
Settings will time out in approximat ely 8 seconds and the device will rev ert back to the
modes window .
NO TE: Certain settings are mode specific and thus cannot be selected in other modes.
GAIN
Gain, in other words the sensitivity , is the depth setting of the device. It is also used to
eliminate the ambient electromagnetic signals fr om the surrounding envir onment and
noise signals transmitted fr om ground.
NO TE: T o obtain maximum depth performance, to eliminat e the noise caused by
electromagnetic interference, try shifting the frequency (FREQ.) first.
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.
NO TE: If the gr ound is highly mineralized causing the device to o verload, 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 pref erence . Howev er , I t is important to set the gain
setting to the highest level possible wher e no major popping sounds are heard to a void
missing smaller and deeper targets. F or example; if the noise level is suitable for sear ching
and is the same at gain levels 40 and 70, then 70 should be pref er r ed. Using the factory
default levels will be a good starting point until you get familiar and experienced with the
device.
Gain in Other M odes:
Since the threshold setting is not av ailable in modes other than GEN, you can increase the
depth of the device or ensure noise-free operation on diff erent gr ounds only by using the
GAIN setting.
In order to adjust the gain in these modes, first g round balance while the gain is at its
default setting. After gr ound balance is completed , hold the search coil stationary or swing
over the gr ound at search height. Reduc e the gain if the device receiv es 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 receiv e noise during searching,
reduce the gain gr adually .
NO TE: G old Kruzer is a high gain device and especially the BOOST mode will run r elatively
noisy compared to other modes so as t o provide the best depth performance. How ever ,
due to the design characteristics of this mode, the noise will be hear d more if the coil is in
free air than sweeping the c oil on the ground. P lease keep this factor in mind while
adjusting the gain.
Discrimination (DISC.)
DISC.is the ability of the device to ignore all metals belo w a certain T arget ID . In the DISC.
process , the discriminated out ID range is shown with lines on the ID scale and ev er y 2
consecutive IDs ar e represent ed with 1 line. F or 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 pr oduce an
audio response for an y metals with IDs bet ween 0-30.
DISC. setting is disabled for GEN mode only . For all other modes , the fac tory default value
will be displayed on scr een at start up.
In order to change the DISC. value, select the DISC. option from the SET TINGS and decrease
or increase the value using the plus (+) or minus (-) buttons . Please remember that c er tain
targets, other than the ones y ou want to ignor e, may also be missed or their sig nals may
become weaker when using the DISC. setting .
When using the DISC. setting, please r emember that other targets, diff erent than the ones
you want to ig nore, tha t fall into the same ID range may also be missed or their sig nals may
become weaker .
In the case of receiving multiple IDs for the same tar get - 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 discriminated out range, the sig nal strength as well as the depth
may diminish.
Threshold (Thresh.)
In the General Search Mode (GEN), search is performed with a continuous humming sound
in the background , also referr ed 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 . I f the threshold is set t oo high, a weak target sig nal may not be
heard. On the c ontrary, if the thr eshold is too low , you give up the depth advan tage this
setting offers. In other wor ds, w eak signals of smaller or deeper targets may be missed . It is
recommended f or average users t o leave this setting at its default value and f or
experienced users to adjust to the highest lev el where they can still hear the weak tar get
signals.
Threshold lev el is directly related to the Gain and iSA T settings. Please be sure to r ead the
related sections of the manual carefully .
iSA T (I nt elligent Self-Adjusting Threshold)
F or the General Search Mode (GEN) to perform accurately , a stable threshold sound is
necessary. Y ou cannot search in the General Search Mode without ground balancing .
Changes that occur in the soil structure and mineralization lev els 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 . iSA T adjusts the speed
that the device rec overs its threshold hum and elimina tes the negative eff ects of
mineralized soils. Increasing the iSA T in high mineralization will enable a more stable
operation by av oiding false signals. This , howev er , may cause some loss in depth and it is
normal.
NO TE: In high mineralization, if you receiv e too many false sig nals without disruption in the
threshold hum, low er the gain first before incr easing the iSA T . I f the false signals con tinue,
set the gain back to its original value and increase the iSA T .
If the mineralization is low , you can decrease the iSA T and sweep the coil more slowly f or a
deeper detection.
iSA T consists of 6 levels. The device will start at level 2. I t is r ecommended that iSA T should
be increased in high-mineralization and decr eased in low mineralization.
iMASK (Intelligent Masking)
This setting is available in all modes ex cept for GEN mode. It is used to eliminate false
signals caused by gr ound noise or hot rocks when searching and the a vailable range is
between 00-10. Its fac tory default value is set to (1). Y ou can change the value using the
plus (+) and minus (-) buttons.
If the device receives a lot of false sig nals due to highly mineralized soil or hot r ocks during
searching , 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. v alues back to their
previous levels . Then, increase the iMASK level until the false sig nals are eliminated .
At the maximum levels of iM ASK, false signals will disappear or will be minimized. Howev er ,
in some cases, increasing the iM ASK will result in loss of depth f or certain metals such as
copper .
NO TE: iMASK value ranges between 00-10. The factor y default is 01. At ''0'' , the iMASK
featur e will be inactive. If the ground is not highly mineralized or does not c ontain many
hot rocks, setting the iM ASK to ''0'' is recommended .
T racking ( TRACK)
Although the tracking setting is selectable in the GEN mode only , it is actually a
common fea ture to all modes so when it is turned on, it becomes active in all modes . The
reason it is selectable in the GEN mode only is that the use of tracking is recommended in
the GEN mode and not in the other modes. After using tracking in the GEN mode, if y ou
switch to other modes and do not want t o use tracking, you need t o select it in the menu
again in GEN mode and turn it off .
When tracking is active (01 position), the device continuously tracks the changing gr ound
structures and automatically reconfigur es the ground balanc e setting. T he invisible
changes in ground aff ect the detection depth as well as the discrimination ability of the
device so it is possible to operat e the device at higher performance using this feature under
suitable ground conditions . Please ref er to page 10 for more inf ormation on T racking.
When tracking is activated, ''T racking'' will be displayed at the bottom of the GB windo w .
NO TE: Tr acking is recommended to be used in the GEN mode only .
Iron V olume (Fe VOL.)
It is ac tiv e in the MICRO mode only . I t adjusts or turns off the volume of the lo w iron tone
in this mode. It can be adjusted between 0-5.

ME T ALS UNDER ROCKS
G old K ruz er incr eases the possibilit y of det ec ting metal tar gets under miner aliz ed r ocks
thr ough the pr oper adjustmen t of y our settings . T he c ombined eff ec t cr ea t ed b y the r ock
and metal t ogether is lo w er than the eff ec t tha t the metal cr ea t es b y itself and the
displayed ID will be diff erent than the metal's expected ID . The displayed ID is formed by
the combination of rock and metal t ogether and gets closer to the ID of the rock if the size
of the metal is smaller in relation to the r ock. Keep in mind that metals under hot rocks will
never appear with their own metal ID . For instanc e, a gold piece under a brick may pr oduce
an iron tone and ID .
If you eliminate hot rocks with a c orrectly adjusted DISC. setting in the search modes other
than GEN, you can hear the signal of the target under the r ock if the target signal has a
slightly great er effect than the DISC. value. The important thing here is that if you detect a
target and dig out a rock, you should note the ID y ou got befor e digging and use it as the
DISC.value the next time.
F or instance; the hot rocks in y our search field tend to g ive IDs around 00-04. In this case,
you should set the DISC. to maximum 05. This way y ou can eliminate r ocks and receive the
signals of metals underneath. If you set the DISC.too high unnecessarily , you will lose
metals along with rocks.
IMPORT ANT! When searching in fields with hot rocks , using the E.U .D featur e (page 20) is
recommended to a void missing metals under hot rocks .
