The Garrett Sea Hunter Mark II: A Powerful Fully Submersible Metal Detector!

Garrett Sea Hunter Mark II Under Water Hunt

The Sea Hunter Mark II has an incredible reputation among both hobbyists and professionals as one of the best submersible metal detectors on the market. It features an advanced microprocessor-driven detecting technology to maximize detection depth and power while eliminating most interference from salt and other ground minerals. It features increased sensitivity, a much faster response time and a superior target elimination mode (Garrett’s Discrete Target Elimination) putting it heads and tails above the competition.

Because the Sea Hunter Mark II is likely to be used in a variety of unusual situations and less than ideal spaces, it is designed to both be rugged in construction and flexible in its use. You’ll be able to use one of four stem arrangements, including the useful short-stemmed Scuba Mate configuration, allowing you to search in tight underwater spots as well as on open land or shallow water environments.

What else can I expect from the Sea Hunter Mark II?

This device features Standard and Discrete Trash Elimination, audio threshold setting, and a multi-level variable elimination knob. The machine’s Standard Trash Elimination is the same standard mode you’ll find on most conventional pulse induction metal detectors. It maintains a continuous background audio threshold while offering a low level of response to variations in the detection signal.

The machine’s Discrete Elimination Mode is an exclusive detection mode for the Garrett Sea Hunter Mark II. It works like a Motion Discrimination mode by providing more precise and greatly enhanced discrimination, only providing a sharp audio response when you locate targets within a customized “accept” range.

The device is also designed for long searches, featuring a hip mount belt to reduce arm strain and a belt pouch for storing under-water treasures on long dives.

Take a look at more features from the Garrett Sea Hunter Mark II:

  • 8’’ PROformance submersible searchcoil: powerful detecting on land or sea
  • Submersible headphones: for clear and accurate underwater treasure hunting
