Garrett Sea Hunter Mark II Waterproof Metal Detector - 1151970

Find more rings and less trash with Garrett’s new Sea Hunter Mark II.

The Mark II boasts a unique, groundbreaking technology in the form of a patented Discrete Trash Elimination mode that discriminates unlike any conventional pulse induction (PI) detector.

Avoiding trash at the expense of valuable targets has long been a problem of conventional PI detectors.

But now, thanks to the microprocessor-driven, Sea Hunter Mark II, you can exclude trash items from detection with little or no effect on targets with a similar conductivity.

This sophisticated detector boasts an enhanced discrimination mode, in addition to a standard one, which enables it to differentiate between targets precisely.

Simply switch on the Sea Hunter II’s Discrete Trash Elimination mode, set the dial to eliminate pull tabs from detection and you’ll still receive signals from most thin gold rings.

This unique search mode helps you to zero in on valuable treasure without digging up a lot of trash.

This underwater metal detector is ideal for Beaches, Lakes, Oceans, and all Waterways.

The Sea Hunter Mark II is an advanced microprocessor-driven instrument that is lightweight, highly durable and easy to use.

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.



  • Circuit type: Pulse Induction technology for automatic cancellation of salt/ground mineralization
  • Audio Threshold, Adjustable: adjust to user’s preference
  • User-adjustable Discrimination/Elimination
  • Hip Mount Belt/Pouch: reduces detector weight for long searches
  • Discrimination Modes: Two operating modes (Standard or Discrete) offer varying levels of non-ferrous target discrimination.
  • Discrete Trash Elimination: use to eliminate most pull tabs and foil without significantly degrading sensitivity for rings and coins.
  • Standard Trash Elimination: provides the deepest possible detection; allows a very slow searchcoil sweep in areas with little trash.
  • Independently sealed battery compartment
  • Search Mode: Non-Motion All Metal Deepseeking Mode with Full Range PI discrimination
