Motion Mode - Fisher Gold Bug Operating Manual

GROUND REJECT PROCEDURE
MOTION MODE GROUND REJECTION
1. Tune as you did in the Auto-Tune mode for a
minimum response to the ground. This time however
you won't have an Audio Threshold Tone to guide
you. Instead, the Gold Bug will start out silently but
respond with a "beep" as the coil approaches or
leaves the ground.
2. You'll have to lower the coil faster than you did
in either of the other two modes, making the
procedure a little more difficult, particularly in
mineralized ground. As an alternate procedure try
adjusting the GROUND REJECT control as you
sweep the coil back and forth about 2 inches off
the ground.
NOTE: In all modes, with just a little practice, you'll soon
learn to do the coarse adjusting as you quickly lower and
raise the coil. And with a little more practice, you'll be
able to fine tune with just one hand, using your thumb as
you raise and lower the coil.
