ZVT (Zero Voltage Transmission) creates ultra‑constant high-power opposite polarity magnetic fields, increasing gold sensitivity. This innovative technology detects gold nuggets at extreme depths.

NEXT LEVEL for all serious gold prospectors, providing substantially improved depth. No longer will you be limited to using either sine wave continuous VLF transmission detectors, that struggle in mineralised ground, or square wave PI transmission detectors, that can be insensitive to varying gold sizes and compositions.

A quantum leap in gold performance with breakthrough new technology from Bruce Candy.

Minelab's new flagship gold detector, the GPZ 7000. Equipped with exclusive Zero Voltage Transmission (ZVT) technology, developed by Bruce Candy, and state-of-the-art features, the GPZ 7000 offers the deepest ground penetration and represents the most significant advancement in gold detecting technologies in years. This revolutionary gold detector will discover the deepest gold in mineralized ground and has the highest sensitivity available to detect even the smallest traces of gold.
