The Minelab Excalibur II 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 beach metal detectors, best underwater metal detectors, and see how Minelab's range stacks up on the Minelab brand page.

The Minelab Excalibur II is a strong pick for underwater, beach 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.
