Discover Under Water Treasures

Find more rings and less trash with the new Garrett Sea Hunter Mark II underwater metal detector. The Garrett 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) metal detector. Avoiding trash at the expense of valuable targets has long been a problem of conventional PI metal detectors.

Filters Out Trash, Perfect for Diving or Snorkeling

But now, thanks to the microprocessor-driven, Garrett 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 Garrett Sea Hunter II's Discrete Trash Elimination mode, set the dial to eliminate pulltabs 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.

Advanced Modes Operation

Three modes of operation are included on this waterproof model. All-metal mode to locate all targets without motion. The standard PI discrimination mode for removing junk metal targets on this model featuring pulse induction technology. Lastly, we have a discrete elimination mode for the ultimate trash removal. The Sea Hunter settings include trash elimination. Trash elimination is also known as discrimination. This unit can be fine-tuned for ultimate sensitivity to precious metals by adjusting the sensitivity adjustment which is also known as the depth control.

Filter Unwanted Junk

All metal deep seeking allows you to detect all targets at extreme depths while metal detecting. To fine-tune this model to your detecting style, you can adjust the audio threshold and discrimination. Scuba diving and snorkeling fans will enjoy the full range submersible headphones while detecting or treasure diving. The hip mount beltpouch control box is convertible so that it can be mounted in a comfortable position to reduce the overall detector weight. With non ferrous target discrimination this detector can be set to distinguish between good items like gold and silver and junk targets like iron and cartridge shells. At the end of the day the key is to find as little trash as possible.

Explore the Most Challenging Environments

For use in difficult conditions, this unit has a microprocessor-controlled salt elimination mode to remove the effects of saltground mineralization. Garrett metal detectors manufacture this device using the latest in surface-mount pc board technology. It also features an audio threshold and a ground balance adjustment to fine-tune the detector to the ground conditions where you are. Unlike conventional pi detectors without standard trash elimination this model can filter out junk. The advantage of this pi detector is the wide range of coil options available to treasure divers.
