the search coil cover the target a few times, the target is probably
junk metal.
False signals can be caused by trashy ground, electrical
interference, or large irregular pieces of junk metal. False signals
are usually broken or non-repeatable.
6.
Try finding other metal in the area. When you find a metal item,
wait a few seconds after the tone stops before continuing, to
allow the detector time to reset (or, press the PUSH button
to return the pointer to the center of the view meter and the
TARGET indicator lights out).
FINE-TUNING THE DETECTOR
After you become familiar with how your detector works, you can
fine-tune it to make it more selective in what it finds.
Discrimination is the detector’s ability to differentiate between types of
metal. The detector’s DISCRIMINATION setting determines whether the
detector will distinguish between different types of ferrous and
non-ferrous metals.
You can set DISCRIMINATION to minimum (fully counterclockwise), to
maximum (fully clockwise), or anywhere in between. As you set
DISCRIMINATION to higher levels, the detector first does not detect
small pieces of silver paper, then thick foil, and finally metal objects like
pull tabs from aluminum cans.
Note: Each time you use the detector in a different area, you must adjust
DISCRIMINATION. Each search location presents new challenges.
