“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. 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.

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.
