Warning messages are shown on the bottom of the display during search. Messages that
may appear are as follows:
Messages
Saturation
It appears on the display simultaneously with the overload alarm sounding like a siren. This
happens when the search coil encounters a near surface or a very large object. The device
reverts back to normal operation if you lift the coil up. If the alarm and the message
continues along a long line, you may be over a long metal such as a pipe.
In case of high mineralization, the device may overload. If the cause of overloading is not a
large metal, it may be the ground itself and this situation may be overcome by lowering
the gain.
Check Coil
It indicates an interruption in the search coil transmitter signal. The search coil connector
may be unattached, loose or disconnected. If you own another detector with the same coil
connector, please be sure that you have not attached the wrong coil by mistake. If none of
the above exists, the search coil or its cable may have a defect. If the issue continues when
you change the search coil, there may be an issue in the coil control circuit.
Pump Coil
It appears when the trigger is pushed forward for ground balancing. Does not indicate any
error or problem. It only indicates what should be done.
