gets. Never raise the sweep coil
while sweeping; sweep back and
forth as if it was a pendulum (see
Figure 18).
If the Tool detects the item, it sounds

a tone and the pointer moves to the
type of metal it found. After detect-
ing metal, switch
MoDe tr1 to tr2
to determine the quality of the metal.
If nothing was detected, try again
(make sure the search coil is being
moved properly).
The detector will respond strongly
6.
when it detects most valuable metal
objects. If the signal does not repeat
after being swept over the target a
few times, the target is probably junk
metal.
False signals can occur from elec-

trical interference, large, irregular
pieces of junk metal, or finding trash
on the ground. False signals usually
occur broken or are non-repeatable.
After finding a metal item, wait a few
8.
seconds after the tone stops before
continuing; this allows the detector
time to reset. You can also press the
red button on the handle to return the
pointer to the center of the viewmeter.
Fine tuning
Once you practice with the unit, you
can fine tune it to make it more selective in
what is found.
adjusting SenSitiVity
To adjust the search coil’s ability to
detect objects at different depths in the
ground, rotate
SenSitiVity between Min
and
MaX. For maximum detection depth,
leave
SenSitiVity set as high as pos-
sible. If the Tool begins to “chatter”, de-
crease
SenSitiVity until the noise stops.
adjusting grounD
For accurate operation, it is criti-
cal that you take the time to correctly set
grounD. grounD tunes out false sig-
nals from mineralized soil.

MoDe to VlF and lower the
search coil to 1/2 to 2 inches above
the ground.
If the pointer swings to the right, turn

grounD to the left.
If the pointer swings to the left, turn
grounD to the right.
Lift the search coil about 12 inches

from the ground and press the red
button on the handle. The pointer will
return to the center. Repeat these
three steps until the pointer stays
close to the center each time you
lower the search coil to the ground.
