IN THE FIELD TECHNIQUES
GROUND B L NCING
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 the 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 presence
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 searchcoil waist
high in the air.
5. Lower the searchcoil 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 searchcoils 1/2 inch
over the ground, further ADJUSTMENT 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"
6. If the detector emits sound with the coil over the ground in STEP 5, further
adjustment of the ground balance KNOB is required as follows:
• Lift the searchcoil waist high
• Rotate the ground balance KNOB clockwise 1/16 of a turn
• Press PINPOINT
• Lower the searchcoil to the ground again
If the detector still emits a tone, repeat the procedure. You are searching for the
ground balance knob positiion where the detector is just silent.
It is important to move the knob in small increments in order to find the first
setting (moving clockwise) at which the detector remains silent. To insure
yourself of the optimal adjustment, move the KNOB slightly counterclock-
wise from a silent-adjusted position to check for the most counterclockwise
silent position possible.
If the KNOB is over-adjusted in the clockwise direction, the detector can lose
sensitivity. An over-adjusted condition can also cause the detector to sound
off when the coil is lifted away from the ground.

SSEMBLY
Adjusting the Armrest
Most people will find the standard position of
the armrest very comfortable. Very large
forearms and short forearms (particularly
children's arms), can be accommodated by
moving the armrest forward.
The armrest may be moved forward or
backwards by removing the single screw
and nut, and then repositioning the 2-piece
armrest. Users with shorter arms may find
the armrest more comfortable in the
forward position. In order to move the
armrest backwards, the plastic plug must be
removed from the aluminum tube.
Armrest Strap
(optional accessory)
The strap is available for purchase as a
separate accessory. Some users prefer to use
the strap when swing the detector vigorously,
in order to hold the detector secure against the
arm.
The detector can also be used without the
strap, with no compromise to detector
balance and stability under most conditions.
