try re-tuning your unit.
Notes:
The detector responds with a strong signal on the meter when it detects most valuable metal
objects. If a signal does not repeat after you sweep the search coil over 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.
Try finding other metal in the area. When you find a metal item, wait a few seconds, to allow the
detector time to reset (or, press the red button on the handle to return the pointer to the center of
the view meter).
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 detectors’ 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.
FALSE SIGNALS
Because your detector is extremely sensitive, trash-induced signals and other sources of
interference might cause signals that seem confusing. The key to handling these types of signals is
to dig for only those targets that generate a strong, repeatable signal. As you sweep the search coil
back and forth over the ground, learn to recognize the difference between signals that occur at
random and signals that are stable and repeatable.
To reduce false signals when searching very trashy ground, scan only a small area at a time using
slow, short overlapping sweeps.
DETECTION HINTS
No detector is 100 percent accurate. Various conditions influence metal detection. The detector’s
reaction depends on a number of things:
