SEARCH MODES
Your CZ-3D has two search modes: 1) Target ID or 2) Autotune. Both
search modes are “motion” modes, meaning the search coil must be
in motion to detect a target.
“BOBBING” THE SEARCH COIL METHOD
10
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.
