When your CZ-21 QuickSilver is properly “ground balanced,”
it will have only a minimal response to ground mineralization.
Precise adjustment of the GROUND control is critical for optimum
performance. The higher the degree of ground mineralization or
the higher the sensitivity setting, the more critical it is to have your
machine properly ground balanced. Once you adjust it in either
the Autotune mode or Target-I.D. mode, you can switch back and
forth between the two modes without resetting. Recheck your
setting occasionally as you search because ground conditions
often change rapidly.
If you have difficulty ground balancing, try reducing your sensitivity
level or moving to another spot just in case you are over a buried
piece of metal. In some areas of high ground mineralization you
may not be able to use the touch pad method.
battery strength.
GOOD BATTERIES: Loud, high pitched tone
WEAK BATTERIES: Soft, low pitched tone or “ticking” sound
BATTERIES NEED REPLACING: No tone
During use, the speaker volume will fade and become
nearly inaudible before the detector performance is
compromised by weak batteries.

PINPOINT:
Activating the PINPOINT feature with the center-
positioned button enters a NO-MOTION detection mode. In
this mode of operation, the detector will emit a monotone
hum whenever metal enters the coil’s field of detection.
To use pinpoint, PRESS the button. The pinpoint button will
not deflect with pressure; you will feel no movement in
the button. A 2nd press of
the button will return you
to your previous motion
detection mode.
A moderate pressure,
applied briefly to the
center
of the button, is
required.
The button requires a
2-second wait between
presses.

I.D. location, your target is probably a piece of iron.
Reducing your sensitivity level, taking shorter, slower
sweeps, or increasing the discrimination level may
reduce the number of false signals caused by trash.
2.
Deep Targets:
Deep targets, just barely within
the range of the CZ-21, may be misidentified. For
example, a deep coin may I.D. as iron, or a deep
piece of iron may I.D. as a coin. There’s not much you
can do to avoid this other than to use your pinpoint
mode to ensure that you are exactly centered over
the target. Or you may reduce your sensitivity level
so you just ignore the very deepest targets.
3. Electrical Interference:
Constant chatter caused by
radio/TV stations, power lines or nearby detectors
operating at one of the CZ-21 search frequencies.
The best solution is to move away from the source
of the interference. You may also try one of the
following:
a)
switch to the Autotune mode.
b)
reduce your sensitivity level.
c)
slow down your sweep speed.
If the interference is only minimal and you wish to
continue searching anyway, test your CZ-21 over a
known target to make sure it’s operating properly.
Inside some buildings, electrical interference may be
so bad that you’ll have to go outside just to bench
test your CZ-21.
4. Highly Mineralized Soil:
May cause a bell tone
response or constant false signals. Check your
ground balance (See page 11). Try lowering the
sensitivity and/or increasing the discrimination level.
Search in the AUTOTUNE mode. Re-ground balance
using the “bobbing” method (See page 13). If all
else fails, raise the search coil just high enough for
the false signals to disappear and then sweep at
that constant height.
