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
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 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
