GPX-4500 metal detector - GPX-4500

The GPX-4500 utilises Minelab’s proven 'Dual Voltage Technology' (DVT). This ensures an accurate Ground Balance to provide maximum sensitivity and depth in all ground types.
The GPX-4500 offers a total of six Timing options, each incorporating the all-new SETA technology. Smart Electronic Timing Alignment (SETA) ensures the detector is precisely aligned for each individual Timing option. This improvement in calibration reduces the susceptibility to certain types of interference, and significantly improves the detector’s immunity to highly magnetic
rocks and soils.
Through a process of dynamic noise compensation, SETA ensures that the threshold stability is improved and maintained, allowing you to operate the GPX-4500 with maximum efficiency under all conditions.
The GPX-4500 now offers six preprogrammed Search Modes, set up for the most common search techniques.
All modes can be fine tuned by simply scrolling through the various functions of the detector and adjusting the settings.
With improved fuctionality and new timings the GPX-4500 is capable of finding nuggets in a diverse range of ground conditions with greater ease than previous detectors.

Rx Gain
The Rx Gain function sets the overall sensitivity level of your detector. In areas where soil conditions are mild you can increase the Rx Gain. In areas that are more difficult Rx Gain can
be reduced.
Timings
The GPX-4500 features a number of new timings, increasing performance in different conditions.
Ground Balance (GB) Type
Ground Balance Type now has three settings: Normal, Specific, and GB Off. Normal is the preferred setting for most soil types. Specific Ground Balance is designed to be used in very hot ground, and is especially useful with Monoloop coils. GB Off switches the ground balance circuit off for maximum depth in very mild soils, sand etc.
Response
The Response function allows you to invert the target response. Deep targets can now sound like the more familiar 'rising and falling' pitch of a shallow target signal.
