SEARCH MODES
Your CZ-5 has two search modes: 1) Target ID and 2) 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 for a very sensitive, wide-
scan, all-metal, motion search mode. Since this mode responds
until there is little or no change in the threshold
level.
4. 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. If 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.
