ABOUT YOUR DETECTOR
2
10.
Search Coils:
The CZ-21 comes with the 8” coil as
standard equipment, but can also be custom
ordered with the 10” coil. All coils are permanently
attached.
11.
Balanced, Comfortable and Hipmountable:
Cushioned
arm rest, soft foam grip and a control housing that
slips off the handle and onto your belt.
12. Salt Water Compensation:
Salt water is electrically
conductive, and therefore induces a strong
signal in the searchcoil. Unlike most other metal
detectors, the CZ-21 uses Fourier Domain signal
analysis to cancel the salt water signal. Under most
conditions you will not experience any false signals
from salt water. When working in the surf zone at
high sensitivity settings you may hear an occasional
“whisper” which is easily ignored.
13.
Easy to Use:
Just pick it up, set the control on the red
circles and start searching in a “coins-only” mode.
Or for maximum performance, adjust the controls
for your own specific situation.
Read this instruction manual thoroughly, practice often and
you’re in for some exciting treasure hunting.

Notes:
1.
Subject to improvement or modification without notice.
2.
Approximate.
3.
Pulsegate Unipolar Audio Processing. Advanced Fisher circuitry which allows
silent operation below “audio threshold tone” with no loss in sensitivity.
4.
The CZ-21 is a “motion” detector while in the search mode. The search coil
must be moving at least slightly to detect a target.
5.
Electro-Static-Insulated to eliminate certain types of false signals.
