Minelab GPZ 8000

The GPZ 8000 is Minelab's flagship gold detector, running GeoZVT on the Zero Voltage Transmission platform that redefined how deep a production machine could find gold. ZVT is neither VLF nor conventional pulse induction: it holds a constant magnetic field and reads the response, which is how it reaches nuggets sitting below the depth other technologies can see at all. This is specialist equipment for prospectors working serious ground, with the sensitivity to catch small gold and the depth to find what earlier machines walked straight over.
