(Setting range is 1-200 with Factory preset at 100)
The detector will respond to the natural
mineralization of the soil and provide the operator
with false signals. It is necessary to Ground
Balance the detector to only register the signals
generated by metal targets.
The Ground Balance procedure is as follows.
Turn ON the detector; PRESS the
button on
menu option
number 1 to open the MGB
(Manual Ground Balance) setting.
Very slowly RAISE and LOWER the search coil up
and down from the ground surface – approximately
6” inches down to 1” above the ground and repeat.
Take note of what the audio does as the coil is in
the DOWNWARD MOTION.
If the audio on the downwards motion is a LOW
tone/pitch increase the MGB by pressing the
button.
If the audio on the downwards motion is a HIGH
tone/pitch decrease the MGB by pressing the
button.
If the ground balance is difficult to achieve or after
setting the ground balance the detector becomes
noisy for no apparent reason. Try a MODE setting
6 to 15 as this will help reduce the feedback from
hot mineralization pockets of ground.
Furthermore keeping the search coil 1” off the ground
can help stabilize the detector at the cost of losing
some sensitivity on some targets.
Higher Mode settings can reduce audio
response on very small targets.
