No-Motion Mode - Fisher Gold Bug Operating Manual

GROUND REJECT PROCEDURE
NO-MOTION MODE GROUND REJECTION
1. Hold the coil 6 to 10 inches off the ground. Push
and hold the RETUNE button a couple of seconds
to reset the threshold tone.
2. Lower and raise the coil and tune as in the AUTO-
TUNE GROUND REJECTION instructions for a minimal
change in the Audio Threshold tone. Note that unlike
the Auto-Tune mode, when the tone changes when
you lower the coil, it stays changed until you raise it
again or until you are properly tuned.
3. If the threshold tone changes when you adjust
the GROUND REJECT control, push and hold the
RETUNE button a couple of seconds before
lowering the coil.
4. As an alternate procedure try placing the coil
on the ground, push, hold and release the RETUNE
button and lift the coil about 6 inches. If the tone
increases put the coil back on the ground and
rotate the GROUND REJECT knob to the right (to
the left if it decreases), push and release the RETUNE
button and lift the coil again. Repeat as necessary.
You may find this method easier but you might also
lose some depth in highly mineralized soil.
