TURN ON PROCEDURE
1. Set your controls as follows:
GROUND = “10”
DISC = “0” for normal use in target I.D. mode. (Set DISC
to “Autotune” for deep search, all-metal AUTOTUNE
mode.
SENS = “10”
VOLUME = OFF
2. Hold the search coil waist high, away from any nearby
metal.
3. Turn the VOLUME control to “1” (A brief bell tone is
normal when you turn the VOLUME control on).
4. Increase the volume to a comfortable level when the
search coil passes over a large, shallow target.
When your CZ-20 QuickSilver is properly “ground balanced,” it
will have only a minimum 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, unless you increase
the sensitivity level or go from dry sand to wet sand or vice versa.
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 pushbutton method.
signal strength. When the SENSITIVITY control is in the
“BATT TEST” position and both LED’s are fully lit up, the
batteries are fully charged. When both LED’s are out,
it’s time to replace the batteries.

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-20, 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-20 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-20 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-20.
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.
5. Black Sand: Same as Highly Mineralized Soil above.
6. Wet Salt Water Sand: Your CZ-20 should be able to
