The Garrett Sea Hunter Mark II has an unparalleled reputation among treasure hunters, law enforcement agencies and various industries as one of the most reliable and sophisticated submersible metal detectors of its kind. The Sea Hunter Mark II is an advanced microprocessor-driven instrument that is lightweight, highly durable and easy to use.

The Sea Hunter's pulse induction (PI) circuitry provides excellent depth and enables you to find treasure without interference from salt water and most ground minerals.

Outstanding Features 

The Sea Hunter's outstanding performance, custom-designed housing and multiple configurations make it superior to other underwater detectors available. Microprocessor-based circuitry in the Sea Hunter provides greater sensitivity, faster target response and comes with Garrett's exclusive Discrete Target Elimination mode.

The custom designed double o-ring sealed housing is durable and lightweight, with individual, o-ring sealed battery and electronics compartments that makes battery replacement hassle free.

An 8" epoxy-filled search coil and custom designed headphones, submersible to 200 feet, make the Sea Hunter Mark II highly stable and reliable. The Sea Hunter Mark II is very versatile, offering four stem arrangements to suit your search needs: the long stem with top stem mount, under cuff stem mount, hip mount and the short stem ScubaMate.

Each arrangement allows you the versatility to search on land, in shallow water or underwater, or in situations where a sealed detector is required.

The ScubaMate is ideal for diving while the long stem allows you to carry the control housing on your waist or shoulder, or stem mounted, is useful for searching on land or in shallow water.
