As shown here, the detector
sounds a low tone when it detects
small gold and nickels, a broken
tone when it detects most pull tabs
and some gold and zinc, and a
high tone when it detects copper,
silver, and brass.
If DISC/ALL
METAL/TONE
is set to
TONE
and
DISC/TONE
has been
properly adjusted, the detector
sounds a unique audio tone for
items such as bottle caps, zinc
pennies, and pull tabs.
Note: Since these indications are
approximations, the detector might
not have actually found the item it
indicates. The indicators are only
references to help you decide if an
item is worth investigating.
If the detector does not detect the
item you placed on the ground,
make sure
DISC/ALL METAL/TONE
is correctly set for the type of metal
you are searching for (see “DISC/
ALL METAL/TONE” on Page 8),
then repeat this step. Also, make
sure you are moving the search-
coil correctly.
Notes:
• The detector responds with a
strong signal when it detects
most valuable metal objects. If a
signal is broken or 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 interfer-
ence, or large oddly-shaped
pieces of junk metal.
7. 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.
FINE-TUNING THE
DETECTOR
After you become familiar with how
your detector works, you can fine-tune
it to make it less sensitive to interfer-
ence and more selective in what it
finds. For example, you can set it so it
ignores most junk metal such as pull
tabs or bottle caps, but still registers
silver and copper coins.
Adjusting SENSITIVITY
For maximum detection depth, always
adjust
SENSITIVITY
set as high as pos-
sible while using the detector. But
broadcast antennas and power lines
can cause the detector to indicate
false signals and operate erratically.
Adjust
SENSITIVITY
lower to help re-
duce or eliminate these false signals.
Turn
SENSITIVITY
clockwise to in-
crease it, or counterclockwise to re-
duce it.
