IN THE FIELD TECHNIQUES
6. If the detector emits sound with the coil over the ground in STEP 56,
further adjustment of the ground balance KNOB is required as follows:
• Lift the search coil waist high
• Rotate the ground balance KNOB clockwise 1/16 of a turn
• Press PINPOINT
• Lower the search coil 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 counterclockwise 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.
As your search takes you to different areas, verify the ground balance set-
ting periodically using the above procedure. Within a geographical area,
ground conditions can change. Varying elevation, proximity to water, and
concentration of rock, sand or clay can all affect ground condition and
sometimes require recalibrating with the ground balance knob.
• If the detector remains silent with the search coil 1/2 inch over the
ground, no further adjustment is necessary; the detector is "GROUND
BALANCED"
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.
