DETAILED OPERATING INSTRUCTIONS
Turn the ‘GP extreme’ On
• Hold the coil away from the ground and metal objects and switch
Power to On.
NOTE When the ‘GP extreme’ is turned Off, important
information (e.g. tuning frequency and ground balance) is
saved in internal memory.
If detection recommences in the same location, the user
should not have to re-tune or re-ground balance the
detector.
Set the Volume Control
Volume should be set so that target signals are clear and easy to
hear but loud signals are not uncomfortable to your hearing.
Set Volume by testing volume levels by passing coil across a large
target and setting volume at comfortable level. Now test very small
target at this level.
Set the Threshold control
• Adjust the Threshold control until the threshold is just audible
through the headphones.
NOTE Small surface objects, as well as large deep objects,
will produce very small changes in the threshold. It is
important to set the Threshold control correctly to ensure
that these targets are heard. Experiment with known targets
to assist in setting all controls to suit your hearing.
