Use Fast when:
A. Hunting over extreme or quickly changing ground
mineralization, or
B. When large ground balancing adjustments are
needed.
Improper ground balance will degrade detection
depth and audio stability. It should not be necessary
to reground-balance every time you turn the machine
on. It will continue to operate with the same ground-
balance level before the machine was turned off.
In the rare event that extreme ground conditions
continue to produce audio signals, increase discrimi-
nation in small increments until the detector becomes
stable. To ensure maximum possible detection depth,
only increase discrimination enough to achieve detec-
tor stability (this should never exceed the 3 setting on
the dial).
. Setting Threshold:
Set the base audio level according to your individ-
ual hearing requirements. The Threshold Adjustment
may also be used to help mask outside noise.
Typically, the sound is set no louder than necessary;
just above silent is recommended.
. Setting Discrimination:
Set the Discrimination control to zero or a low
level until you are familiar with the conditions of
