False signals can be caused by trashy
ground, electrical interference, or large
irregular pieces of junk metal. False
signals are usually broken
omon-repeatable.
Try finding other metal in thc arca.
When you find a metal item, wait a few
scconds, to allow the detector time to
rcset (or, press the red button on the
handle to retum 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 selcctivc in what it finds.
Discrimination is the detectors' ability to
differentiate between types of metal. The
detector's
DISCRIMINATION setting
detennines whether the detector will
distinguish between different types of ferrous
and non-ferrous metals.
You can set DISCRIMINATION to minimum
(fully countcrclockwise), 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 scarch location
presents ncw challenges.
FALSE SIGNALS
Because your detector is extremely sensitive,
trash-induced signals and other sources of
interference might sause 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
ti
me using slow, short overlapping sweeps.
DETECTION HINTS
No detector is 100 percent accuratc. Various
conditions influence metal detection. The
detector's reaction depends on a number of
things:
•
The angle at which the object rests in
the ground
