Minelab Excalibur II
Designed for underwater work, this professional dive detector is waterproof to a full 60 meters and runs on BBS technology, which sends out 17 frequencies at once (1.5 to 25.5 kHz) to keep performance stable and accurate in salt water and mineralized sand. The housing is phosphorescent for high visibility, two interchangeable shafts are supplied (a standard land shaft plus a short dive shaft), and the headphones are wired and integrated. It is the leading option for shipwreck searches, beach work, and deep dives.

Designed for underwater work, this professional dive detector is waterproof to a full 60 meters and runs on BBS technology, which sends out 17 frequencies at once (1.5 to 25.5 kHz) to keep performance stable and accurate in salt water and mineralized sand. The housing is phosphorescent for high visibility, two interchangeable shafts are supplied (a standard land shaft plus a short dive shaft), and the headphones are wired and integrated. It is the leading option for shipwreck searches, beach work, and deep dives.
The Excalibur II stands as Minelab's premier deep-diving detector, built around the exclusive BBS (Broad Band Spectrum) technology that transmits, receives, and analyzes 17 frequencies simultaneously — delivering strong detection depth, high sensitivity, and excellent discrimination across a wide range of target types.
Fully waterproof to 60 meters (200 feet), it is built for professional divers. RCB technology amplifies weak signals within the coil itself, cutting electrical interference and preserving signal strength from deep, faint targets.
The exclusive Iron Mask feature overcomes the masking effect of nearby iron, keeping gold, silver, and coin signals audible even in iron-heavy areas, while a high-visibility phosphorescent housing makes the detector easy to see in low light or murky water.
Control is handled through simple analog dials rather than a display: a Discriminate mode with adjustable rejection, an All-Metal/Pinpoint mode for precise target location, and a dual-shaft design that switches between a standard land shaft and a compact dive configuration.
