and accepted at each DISC level. For example, "foil"
is placed between DISC = "2" and
means that foil is accepted at "2" and rejected at
"3."
12. You may expect varying signals over different
targets and at different levels of discrimination.
Note that as you progressively increase the
discrimination level, more and more targets are
eliminate.
13. Now switch the DISC control to the AUTOTUNE
position and note the completely different kind of
response. No tone, just a smoother, solid response
over every target.
NOTE: Due to the virtually infinite variety of sizes, shapes and
alloys of many "good" targets (relics, jewelry, foreign coins,
etc.), they may be misidentified. For example, a Civil War mini
ball may be identified as foil, or a new Canadian coin as a
rectangular pull tab.
SEARCHING ON LAND OR SHALLOW WATER
Good search techniques are every bit as important as having a
good detector.
1. Make sure your CZ-20 is properly ground balanced.
2. Decide which search mode you're going to use. Target
I.D. is the recommended starting point with the DISC
control set at "4" or Autotune.
3. Set your SENSITIVITY control. Only experience will tell
you how to set it in every situation, but you'll probably
want to run it as high as you can. Recommended
starting point: SENSITIVITY = "5." If you're in the Autotune
mode, set it so that you can just barely hear a slight
audio hum.
4. Adjust your VOLUME control. Remember that a setting
above "5" will amplify the response of faint targets so
that they sound like a shallow or large target. Some
searchers prefer not to use it above "5" so that the
DISC = " 3." This

strongest audio response. The only difference is that you should
use as short stroke as possible (4-6 inches is plenty). When you
stop the coil you will lose the audio signal. You MUST keep the
coil moving at least slightly to determine the location of the
strongest signal.

TARGET IDENTIFICATION

Target I.D. with the CZ-20 is quick and simple. Just keep in mind
these two rules:
1) You must be in the Target I.D. mode.
2) The center of the search coil must pass directly over the
target.
It's always a good idea to walk slowly and overlap your
sweeps. But if you're searching a large expanse of new territory,
you may want to walk a little faster and not overlap your sweeps
as much until you start making a few good finds. Then, slow down,
overlap your sweeps and cover every inch of ground.
In trashy areas, to reduce the "masking" effects of trash on
nearby good targets, use a shorter and slower sweep pattern.
If you're going to be hunting exclusively in this type of ground,
you may be better off equipping your CZ-20 with the smaller, 5-
inch coil at time of purchase. It will zero in on good targets closer
to trash.
1. Once you've located a target, pinpoint its exact
location as in the "Pinpointing" procedure. Since
accurate I.D. is dependent on accurate
pinpointing, it is recommended that you press the
PINPOINT button rather than try to pinpoint your
target in either the Autotune or Target I.D. mode.
2. Once you've pinpointed your target, release the
PINPOINT button. If you're searching in the
Autotune mode, switch over to DISC = "0." If you
are already in the Target I.D. mode, just leave the
DISC control where it is.
