recommended for maximum detection depth unless:
A. The detector is not properly ground balanced, or
B. You are hunting in changing ground mineralization
conditions that require continuous ground tracking.
Improper ground balance or changing ground
mineralization are identified by erratic audio signals
caused by the ground. If you experience these sig-
nals, you will need to switch the rotary dial to fast or
slow. It is recommended that you ground balance the
machine before continuing.
To ground balance the detector, turn the Automatic
Ground Track switch to either fast or slow, and bob
the coil up and down approximately one to six inches
above the ground. When the detector's audio signal
smooths out, move the Automatic Ground Track rotary
switch to lock and the unit will lock the ground track
setting at that value.
If erratic audio signals continue, you may need to
turn the Automatic Ground Track to slow or fast and
hunt in one of those modes.
Use Slow when:
A. Operating over slowly changing ground
mineralization, or
B. When small ground balancing adjustments are
needed.
