The Garrett Sea Hunter Mark II metal detector was introduced in 1999 and is still in production. The Sea Hunter is a fully submersible pulse induction (PI) metal detector aimed primarily at beach and underwater detecting. The Sea Hunter Mark II is submersible to 200 feet and therefore suitable for SCUBA diving.
"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." Source: Owner's manual
