The Minelab GPZ 8000 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.
