The XP Deus II sits in XP's lineup alongside XP ORX, XP Deus, XP XTREM HUNTER. 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 underwater metal detectors, and see how XP's range stacks up on the XP brand page.

The XP Deus II is a strong pick for underwater 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.
