FALSE SIGNALS
24
A “False Signal” occurs when something sounds like a good
target, but is not. Your CZ-3D does a great job of discriminating,
but bad “targets” with similar electrical characteristics can fool
it. Large pieces of trash or items very close to the search coil will
occasionally sound “good”. Experience is the best teacher. As
you accumulate more hours with your CZ-3D, you will soon learn
how to distinguish “false signals”. Initially when you pass over a
target, and get a good response, you will find that crossing over the
target once or twice more, the signal will break up or completely
disappear.
The following are some sources of false signals and the solution:
1. Electrical Interference: Caused by radio and TV towers, power
lines, or other metal detectors.
SOLUTION: Move farther away from the source, slow down the
sweep speed, or lower the sensitivity.
2. Highly Mineralized Soil: Soils with a high iron or salt content.
SOLUTION: Reduce the sensitivity, raise the discrimination level or
readjust the ground adjust setting..
3. Extremely Trashy Areas: May result in a lot of “chatter”.
SOLUTION: adjust the discrimination level or reduce the sensitivity.
In some areas, a smaller coil will be beneficial to better achieve
target seperation.
4. Metal Interference: The CZ-3D will pick up metal ABOVE and
on the SIDE of the coil, as well as under. WATCH FOR: Large metal
structures, your digging tool, metal in shoes and your coil cable
hanging loose above the coil.
