RECOVERY TOOLS

A heavy duty blunt screwdriver, sturdy hunting knife,  or garden 

trowel are commonly used.  Made especially for the Hobby of 

Metal Detecting are several well designed sand scoops, trowels, 

and digging tools .  See your local dealer for more information.

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
