The Minelab GP extreme is the first detector to use Dual Voltage Technology (DVT).
Minelab have developed Dual Voltage Technology (DVT) based on the Bi-Polar technology used in its military detectors.
The new features of the GP extreme are:
- DVT technology giving greater depth than ever before;
- Selectable Tx (transmit) modes for different soil conditions;
- Selectable Rx (receive) modes for increased sensitivity andless susceptibility to interference;
- Adjustable signal response for target tone variation;
- Volume limiting for user's own preference; and
- New GP extreme 1100 and GP extreme 1800 coils which have been specifically designed to take advantage of the new DVT.
Minelab are confident that you will find the GP extreme to be the ultimate detector for finding metallic objects in highly mineralized and/or salty environments. Simple operation means that both the beginner and professional alike will find this detector very easy to use.Old gold fields, where mineralized ground and too much rubbish have shielded many nuggets from the prying eyes of other detector operators, will likely yield new finds when using the GP extreme.
Dual Voltage Technology (DVT)
Dual Voltage Technology (DVT), the foundation of the GP Extreme's advantage, refers to the changes in voltage used to create the electro-magnetic field transmitted into the ground by the detector's coil.
When using a detector, strong magnetic fields are transmitted which can "magnetically saturate" the ground adversely affecting the performance of the detector.
Minelab have found, that by applying two different voltages to the transmit coil it cancels signals caused by magnetic saturation.
This canceling of signals significantly improves the detector's ability to balance out Mineralization, enabling it to produce incredible increases in depth and sensitivity as shown in the diagram below.
