Ground Balance

The device will return to the main screen automatically after a moment upon completion 

of ground balance. To return immediately, just pull and release the trigger once.

IMPORTANT!

 Experienced detectorists adjust the ground balance setting to little 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.

TRACKING

In this option, the user does not need to make any adjustments. TRACKING feature is 

activated from the menu by switching it to 01 position. The word ''Tracking'' is displayed in 

the GROUND PHASE box at the upper right corner of the screen. 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 GROUND PHASE window.  It does not provide any 

feedback to the user (like ground balance value or a 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.
It is recommended that you use TRACKING in the All Metal mode and not in the 

discrimination modes (Two Tone, Three Tone, Beach and Deep) for the best performance.
TRACKING is suitable for use in areas where different soil structures are present within the 

same land or in fields where mineral 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 high mineralized rocks or you may miss the smaller or deeper metals.

IMPORTANT!

 Ensure that TRACKING is off during air tests. Otherwise, the device attempts 

to perform ground balance on the target and the depth is 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
