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 eliminated.
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.
Good search technique is very important to successful treasure
hunting.
1.
Make sure your CZ-21 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
audio response corresponds directly to the depth

Target I.D. with the CZ-21 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.
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 tap 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, tap the
PINPOINT button again. 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.
3.
Move the coil just enough, left-right-left, across the
target to get a good, solid signal. If you no longer
get a signal after you’ve pinpointed your target,
then you’re over something that falls below the DISC
setting you’ve chosen, and your CZ-21 is rejecting
it.
4.
Once you’ve pinpointed your target and you’re
getting a good, consistent signal, you’ve identified
or at least classified your target. A low tone means
your target is probably ferrous. A mid tone indicates
a pull tab or foil, and the high tone indicates a U.S.
