GROUND BALANCING
have gone past the correct ground-balance
setting. Increase the ground-balance level
(rotating the control counterclockwise) in small
increments until there is little or no change in the
threshold level.
7. With a little practice, you should be able to
ground balance quickly by “bobbing” the coil up
and down in a continuous movement as you adjust
the GROUND control with your thumb.
NOTES:
1. If you get an audio response as you first lower the coil with
the GROUND control at 10, you’re probably over a piece of
metal. Move and try again.
2. lf you get a sudden bell tone, not preceded by an increasing
audio response, you’re probably in some very highly
mineralized soil or sand. Instead of lowering the coil to an inch
or two above the ground (as in step 2 above), stop just before
you hear the bell tone and ground balance as instructed.
Maintain that coil height as you search.
3. If you don’t get an audio response, or if the hum stays the
same no matter where you set the GROUND controls as you
bob the coil up and down, you’re probably in an area where
there’s very little ground mineralization. Just leave the
GROUND control at “10” and begin searching.
