Minelab GPZ 7000 Gold Metal Detector with Zero Voltage Transmission (ZVT)
At a glance
The Minelab GPZ 7000 uses ZVT (Zero Voltage Transmission) technology for extreme depth on gold in mineralized ground. It remains the reference metal detector for gold at depth, the GPZ 7000 metal detector being the gold detector prospectors grade newer machines against. 3.32 kg (7.32 lb) with the standard 14x13 in Super-D coil and battery, coil waterproof to 1 m (3.3 ft, control box not submersible), integrated GPS, and up to 8 to 10 hours of runtime on the removable Li-ion pack. 3 year warranty.

ZVT: Depth Built for Difficult Ground
The GPZ 7000 runs Minelab's Zero Voltage Transmission technology, engineered specifically for gold prospecting in mineralized, iron-stained, and salt-affected ground where conventional VLF and PI detectors lose signal to ground noise. The 14x13 in Super-D coil pairs a central transmit winding with two outer receive windings to cut mineral interference and hold a stable threshold, so faint deep signals on fine and large nuggets alike stay readable instead of drowning in ground chatter.
Wi-Stream wireless audio (under 10 ms lag) pairs with the included Koss UR-30 headphones or the WM 12 wireless module, and a built-in GPS logs and maps your finds through the included X-Change 2 software, so a season of ground you have covered is never a guess.

Who it is for
The GPZ 7000 is a serious gold prospecting machine for detectorists working mineralized ground where depth on fine and deep nuggets matters more than speed or weight. If you want the widest coil selection and the most recent Minelab gold platform, see the GPZ 8000. For a lighter, PI-based option on modern gold ground, see the GPX 6000.
Frequently Asked Questions
Is the GPZ 7000 waterproof?
The 14x13 in Super-D coil is waterproof to 1 m (3.3 ft). The control box and the WM 12 wireless module are not submersible.
How much does the GPZ 7000 weigh?
3.32 kg (7.32 lb) with the standard coil and battery attached, per Minelab's published specifications.
What is ZVT technology?
Zero Voltage Transmission is Minelab's ground-balancing transmit technology built for gold prospecting in mineralized ground, engineered to hold a stable threshold and pull faint deep signals out of ground noise that would mask them on conventional detectors.
How does the GPZ 7000 compare to the GPZ 8000?
The GPZ 8000 is Minelab's newer gold platform, running GeoZVT with a lighter 2.78 kg (6.1 lb) bare detector weight and a broader coil range (Z13, Z17, Z18). The GPZ 7000 remains a proven ZVT machine at a lower price point.
