The Minelab GPZ 7000 sits in Minelab's lineup alongside Minelab Equinox 700, Minelab Equinox 800, Minelab Go-Find 66, Minelab Gold Monster 1000. It uses Simultaneous multi-frequency — transmitting several frequencies at once and combining the returns. Near-VLF discrimination with near-PI ground handling: the processor subtracts the salt/ground response while keeping target signal. Costs more and drains batteries faster, but it's the best all-round answer for mixed ground. Compare it against its intended competition in our guides to the best gold prospecting detectors, and see how Minelab's range stacks up on the Minelab brand page.
The Minelab GPZ 7000 is best for gold detecting. Key strengths: zvt technology (up to 40% deeper than gpx series).
The manufacturer has not published the operating frequency on its official pages, so we list it as not published rather than guessing.

The Minelab GPZ 7000 is a strong pick for gold detecting, but no machine is universal. Check the waterproof line before any water use, confirm the weight against your stamina, and remember that ground conditions affect real-world performance more than any spec number.
