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
GPX4500
Frequency control
We fit the GPX4500 with a high quality rotary switch for the frequency control allowing 5 different frequencies (level 3 mods) 0r 8 different frequencies (level 4 mods) 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(level 3) or 3 frequencies(level 4) lower than standard for larger coils, standard frequency, and 2 frequencies (level 3) or 4 frequencies (level 4)higher than standard allowing the detector to be set incrementally to its highest sensitivity. The level 4 mods being the latest allow sensitivity in the realms of the 6000 and depth that the 7000 users can only dream of.
Gain control
The GPX front end low noise 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 yourself and others. Our gain control comes with a mark to show where the factory gain is. When you know this, you will detect with confidence!
Repairs
We also check the detector and perform any minor repairs that are required, most common being worn power plug and flexible strip.
GPX4800
Frequency control
We fit the GPX4800 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.

GPX5000

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(level 3) or 3 frequencies(level 4) lower than standard for larger coils, standard frequency, and 2 frequencies(level 3) or 4 frequencies(level 4) higher than standard allowing the detector to be set incrementally to its highest sensitivity. When set to the highest frequency in Fine gold the 5000 matches or exceeds the performance of the gpx6000 on the smallest most difficult gold and specimens with small coils and with larger coils depth that the 7000 users can only dream of.
