Search Modes; Auto Tune - Fisher M-Scope CZ-5 Quicksilver Operating Manual

"BOBBING" THE SEARCH COIL METHOD
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. 1f 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. It will then be
necessary to maintain that coil height as you search.
3. lf 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.

SEARCH MODES

Your CZ-5 has two search modes: Target ID and Autotune. Both
search modes are "motion" modes, meaning the search coil must
be in motion to detect a target.
AUTOTUNE SEARCH MODE
Set the DISC control to Autotune and you're in a very sensitive,
wide-scan, all-metal, motion search mode. Since this mode
same (or changes very little) as the coil is lowered
and raised.
6. If the hum gets louder as you lower the coil, you
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.
