Notes:
• The detector responds with a
strong signal when
it
detects
most valuable metal objects. If a
signal does not repeat after you
sweep the searchcoil over the
target a few times, the target is
probably junk metal.
• False signals can be caused by
trashy ground, electrical inter-
ference, or large irregular
pieces of junk metal. False sig-
nals 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.
FALSE SIGNALS
Your detector is extremely sensitive,
and will find even deeply-buried metal.
Because of this, trash-induced signals
and other sources of interference
might cause signals that seem confus-
ing. The key to handling these types of
signals is to dig for only those targets
that emit a strong, repeatable signal.
As you sweep the searchcoil back and
.J.-
forth over the ground, learn to recog-
nize the difference between signals
that occur at random and signals that
are stable and repeatable.
To reduce false signals when search-
ing very trashy ground, scan only a
small area at a time using slow, short
overlapping sweeps. To help prevent
erratic signals and pinpoint targets
in
trashy areas, try a smaller searchcoil
(see "Optional Accessory" on Page 2).
FINE-TUNING THE
DETECTOR
After you become familiar with how
your detector works, you can fine tune
it
to make
it
less sensitive to interference
and more selective
in
what it finds. For
example, you can set
it
so it ignores
junk metal such as pull tabs but still reg-
isters silver and copper coins.

Broadcast antennas and power lines
can cause the detector to indicate
false signals and operate erratically.
Adjust
SENSITIVITY
on
the front of the
detector
in
any target mode, to help re-
duce or eliminate these false signals .
To adjust the sensitivity, turn
SENSI-
TIVITY
clockwise to increase
it,
or
counterclockwise to reduce
it.
