Coils for Garrett Sea Hunter Mark 2



The Garrett Sea Hunter Mark 2 is a reliable, effective, easy-to-operate, professional underwater metal detector. It is designed for underwater search of valuable items at a depth of up to 60 meters. The device is specially engineered for comfortable underwater hunting: adjustable shaft length, convenient location of controls and enhanced reliability against leaks. The Sea Hunter Mark 2 helps search equally well on land, in water as well as underwater. The device operates without loss of depth not only in highly mineralized and salty soils, but also in sea water.


The electronic circuitry of the Garrett Sea Hunter Mark 2 metal detector is based on pulse induction technology. It operates at a frequency of 0.75 kHz. The detector has no visual indication, therefore the types of metals are identified aurally. The Sea Hunter Mark 2 is controlled by using three potentiometers, this greatly simplifies program setting and switching underwater. For example, the audio level is set by rotating the THRESHOLD potentiometer, the discrimination level is adjusted by using the ELIMINATION one, whereas the SEARCH MODES knob turns the unit on and switches between the Standard and Discrete Trash Elimination modes. A 6.35mm headphone jack is located on the front panel near the potentiometers.


The Garrett Sea Hunter Mark 2 metal detector comes standard with a Garrett 8’’ PROformance Mono coil. For this device there exist other coils of different sizes and parameters. The power supply of the unit is 8 AA batteries. The size of the detector is adjusted in the range of 71-132cm. The weight of the Garrett Sea Hunter Mark 2 (assembled) is 2.3kg.

    • hi, I saw your post from last October and want to know if you’re willing to enter a few questions about your Garrett Sea Hunter II?

      I assume you are using the 8-inch coil? What is your typical detection depth under the sand provided you are in the water? Do you have the 10 by 14-inch coil and if so, how is that been for you? Better performance? detection depth? if you could do it all over again, would you still buy the detector? Any other suggestions would be very helpful and appreciated.
