Scuba Metal Detectors for Diving, Wreck Salvage & Deep Recovery
Past the splash zone, water hunting becomes a specialist's game. Every machine and recovery tool on this page is pressure-sealed for real diving — rated from 65 feet to 250 — built for water where an ordinary "waterproof" detector floods in minutes. The XP DEUS II covers recreational scuba to 65 feet with full simultaneous multi-frequency and modern target ID. Below that, the purpose-built dive machines take over: the Minelab Excalibur II, sealed to a full 200 feet, alongside pulse-induction units that hold stability in salt water and black sand — with housings, connectors, and headphone seals engineered for pressure rather than splash. This is the gear for shipwreck salvage, deep-lake recovery, and underwater archaeology. If you want the full picture on depth ratings, salt performance, and how the machines compare, our underwater metal detector guide walks through every machine we sell for water.
Reading a Depth Rating at Scuba Depth
At these depths the rating is everything: water pressure roughly doubles every 33 feet, so a machine rated to 65 feet and one rated to 250 are built to genuinely different pressure tolerances, not marketing tiers. Buy to the deepest water you will actually dive, then leave a margin — exceeding a pressure rating does not just risk a leak, it can implode a seal. Confirm that every component you submerge, including headphones and connectors, carries the same rating as the control box. Wired headphones are standard on dive machines by design: wireless audio does not transmit through water. When the gap between two ratings is small in price, size up.
Match Every Component to the Depth
Deep recovery is a kit, not a single machine. A depth-rated pinpointer is what actually gets the target out of the hole in low visibility, and the purpose-built ones live here: the Quest Scuba Tector, the Nokta PulseDive, and the Treasure Products Vibra range are sealed for diving just like the detectors beside them. Add a diving scoop or recovery tool suited to the bottom you are working, and submersible search coils matched to your machine. At depth, redundancy and rating matter more than features.

Where This Tier Stops and the Next Begins
If you never leave the surface, you do not need a dive machine. Surf, snorkel and wading work is covered by our underwater & waterproof metal detectors — lighter machines, lighter prices — and dedicated beach & saltwater detectors handle wet sand and the towel line. This page is for hunting that happens on a tank.
Why Buy a Scuba Metal Detector from Serious Detecting
At scuba depth a rating has to be real — a failed seal at 100 feet is an expensive, unrecoverable loss. Serious Detecting is an authorized US dealer, so the pressure ratings here come with genuine manufacturer warranties behind them. Orders over $99 ship free out of Michigan, local pickup is open, and the staff hunts water. Tell us how deep you are diving and we will make sure the machine, and every component on it, is rated for where you are taking it.
