Waterproof Metal Detectors 65–196+ Feet

Underwater metal detectors rated to 65 feet or deeper are purpose-built for actual dive detecting - snorkeling and scuba depths where 10-foot machines cannot follow. The XP DEUS II at 65 feet is the most capable multi-frequency option. The Garrett Sea Hunter MkII at 200+ feet is purpose-built for deep underwater pulse induction work. For most beach and river hunters, 10-foot waterproofing is sufficient.

Whether you're searching shipwrecks, scanning deep lakes, or investigating underwater archaeological sites, these detectors deliver precise target identification, maximum stability, and consistent detection at 65–196+ feet. Gear up and push your adventure further with detectors built to perform where few others can.

Underwater Metal Detectors for Dive Detecting: Purpose-Built for Depth

Most detectorists who think they need a dive-rated machine actually only need 10-foot waterproofing for surf wading and river work. The machines in this category are for true underwater detecting — snorkeling in shallow reef areas for dropped jewelry, scuba detecting in rivers and harbors for historical artifacts, and underwater salvage work. If you are not going beyond wading depth, a standard waterproof machine will cover your needs.

XP DEUS II – 65 Feet, Full Multi-Frequency Performance

The XP DEUS II is one of the few machines that combines real dive capability with full multi-frequency performance. Rated to 65 feet across the remote, coil, and WS6 Master headphones, it delivers consistent detection performance at depth without sacrificing capability on land or beach. For hunters who want one machine that works equally well above and below water, the DEUS II stands out. See XP DEUS II.

Minelab Excalibur II 1000 – Proven Underwater Performance

The Minelab Excalibur II 1000 is one of the most established underwater metal detectors, built specifically for serious dive detecting and surf work. Fully submersible to 200 feet, it uses Minelab’s multi-frequency BBS technology to maintain stable performance in saltwater environments while still providing effective target detection. Long proven in real-world beach and dive conditions, the Excalibur II is a dedicated underwater machine trusted for both shallow surf hunting and deeper dive work.

Waterproof Accessories for Dive Detecting

For underwater detecting, accessories must match the depth rating of your detector. A purpose-built option like the Nokta PulseDive provides reliable target location underwater. Pairing your detector with proper sand scoops designed for underwater recovery ensures efficient retrieval at depth.
