Adjusting the Arm Rest
Most people will find the standard position
of the arm rest very comfortable. Very large
forearms and short forearms (particularly
children’s arms), can be accommodated
by moving the arm rest forward.
The arm rest is adjustable to three positions.
To adjust, remove the screw from the
underside, then press the silver button
and move the arm rest to one of the
alternate positions. If you cannot fully
depress the button with your finger, use
a narrow object, such as the blunt end
of a ballpoint pen. The arm rest must
be twisted with moderate force to move
it to an alternate position; this
adjustment is usually made infrequently.
If desired for added
stability, re-install the
screw. The screw is not re-
installed in the furthest forward
position.
If the button becomes disengaged inside
of the tube, remove the plastic cap at the
end of the tube to access the clip inside.

IN THE FIELD TECHNIQUES
- Pinpoint Mode
GROUND BALANCING
Before using the PINPOINT mode, it is necessary to ‘Ground Balance”
your detector, this ground balancing adjustment offsets the effects of
minerals and slats in he ground.
To GROUND BALANCE your detector:
1.
Using the ALL-METAL mode, find a patch of ground which is free of metal
objects. You will use this section of ground to test the detector. The pres-
ence of any metal objects in this area will interfere with this procedure.
2.
Begin with the ground balance KNOB
in the PRESET position.
3.
Lift the search coil waist high in the air.
4.
Press the PINPOINT touch pad.
5.
Lower the search soil to the ground, maintaining
it elevated about 1/2 inch above the surface (be
sure that this ground does not contain metal).
• If the detector emits sound with the search
coils 1/2 inch over the ground, further
ADJUST-
MENT IS NECESSARY.
• If the detector remains silent with the
searchcoil 1/2 inch over the ground,
no further adjustment is
necessary; the detector
is
“GROUND
BALANCED”
