FALSE SIGNALS
pinpoint mode to insure that you are exactly
centered over the target. Or you may reduce the
sensitivity level and ignore the very deepest
targets. Fortunately, misidentification of deep
targets is not what usually happens. It’s the
exception to the rule.
3. ELECTRICAL INTERFERENCE: Constant chatter
caused by radio, TV stations, power lines or nearby
detectors operating at one of the CZ-5 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.
d) Use the optional 5 inch search coil.
If the interference is only minimal and you wish
to continue searching anyway, test your CZ-5 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-5.
4. HIGHLY MINERALIZED SOIL: May cause a belltone
response or constant false signals. Check your
ground balance (see the “GROUND BALANCE”
section referring to mineralized soil), and make sure
your MODE switch is in the proper position. If it is,
try switching to the SALT mode and re-ground
balance.
Try lowering the sensitivity and/or increasing the
discrimination level. Search in the AUTOTUNE mode.
Use the optional 5-inch search coil. Re-ground
balance using the “Bobbing” method. 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.
