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 salts 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 search coil waist high in the air.
4. Press the PINPOINT
