GPX4000

Frequency control

We fit the GPX4000 with a high quality rotary switch for the frequency control allowing 5 different frequencies to be selected. Just like gold and coils come in all different shapes and sizes, the frequency control allows the detector to be optimized for the coil you have fitted. There are 2 frequencies lower than standard for larger coils, standard frequency, and 2 frequencies higher than standard allowing the detector to be set incrementally to its highest sensitivity.

Alternately we can make the detector frequency be controlled by the manual tune. Doing it this way you loose your fine control for tuning out interference.

Gain control

The GPX gain control was specifically designed for the GPX series. The gain control allows the detector to be adjusted for ground and emi conditions, whichever is worse. By adjusting the gain for the ground you are working you maximize the detectors ability to detect gold missed by others. Our gain control comes with a mark to show where the factory gain is. When you know this, you will detect with confidence!

Channel Select Switch

We also fit our channel select switch. Generally ch1 has the least ground noise, but in some timings it still remains sensitive to small targets.


Repairs

We also check the detector and perform any minor repairs that are required
