Notes:
SENSITIVITY also turns the detec-
tor
on
and off.
For maximum detection depth,
always leave
SENSITIVITY set as
high as possible while using the
detector.
If you set the detector's sensitivity
too high, the top display might ran-
domly display arrows and the
detector might sound false tones.
Adjusting DISC/NOTCH
Discrimination is the detector's ability
to differentiate between types of metal
and either find or ignore them.
DISC/
NOTCH
adjusts the detector's discrimi-
nation.
If the detector
is
set to the DISC or
AUTO NOTCH target mode, adjust
DISC/NOTCH clockwise toward HIGH to
set the detector to ignore items such
as bottle caps, zinc pennies, and pull
tabs, while still detecting items such as
nickels and small gold items.
Notes:
Adjusting DISC/NOTCH has no
effect
in
the ALL METAL target
mode.

If
you set the detector's discrimi-
nation too high, the detector will
not detect some gold items.
PINPOINTING A TARGET
Accurately pinpointing a target while
detecting makes digging it
up
easier.
Accurately pinpointing small metal ob-
jects takes practice.
We
suggest that
you practice finding and digging
up
small metal objects
on
your own prop-
erty before you search other locations.
Follow these steps to pinpoint a target.
1.
When the detector detects a bur-
ied target, continue sweeping the
searchcoil over the target
in
a nar-
rowing side-to-side motion.
2.
Make a visual note of the exact
spot
on
the ground where the
detector beeps.
3.
Stop the searchcoil directly over
this spot
on
the ground. Then
move the searchcoil straight for-
ward away from you and straight
back toward you a couple of times.
4. Make a visual note of the exact
spot
on
the ground where the
detector beeps.
5.
If
necessary, repeat Steps
1-4
to
zero
in
on
the exact spot
on
the
ground where the detector beeps.
