Fisher M-SCOPE CZ-3D - Search Coil Movement and Patterns

NOTE: Unlike other metal detectors, the discrimination level has little
if any effect on the depth capability of the CZ-3D. Note however, that
the all-metal, Autotune mode has a wider search pattern and may
detect a little deeper. Depth is also determined by the size, shape
and conductivity of the target as well as the sensitivity setting of
the CZ-3D.
1. Minimum Depth
a. Very slow or fast sweep speed.
b. Discrimination set at “6.”
2. Good Depth
a. Moderate sweep speed.
b. Discrimination set at “4.”
3. Maximum Depth
a. Moderate sweep speed.
b. Discrimination set at “0.”
4. Missed Target
Many targets within range will not
be detected unless you closely
overlap your sweeps.

When the stem length is properly
adjusted, the CZ-3D is balanced for
sweeping in a tight semicircle. Wide to
the right for right handers. Wide to the
left for left handers.Be sure to overlap
your sweeps.

Keep the search coil parallel and
close to the ground at all times.
