Product Description

Garrett Sea Hunter Mark II Metal Detector
with 8" Open Search Coil Plus FREE Metal Detecting & Treasure Hunting Accessories

Ideal for Beaches, Lakes, Oceans, and all Waterways. The Sea Hunter has been The Master of Water Treasure Hunting for over 25 years. With it’s unique Discrete Trash Elimination technology, the Sea Hunter Mark II can eliminate most pull tabs and foil without significantly degrading the sensitivity of rings and coins in Discrete Elimination mode. A favorite detector for treasure hunters around the world because of it’s ability to ignore salt water, the Sea Hunter’s electronic housing can be mounted on the hip or above, below or under the cuff in either short or long configuration.

If you want a submersible PI detector that really discriminates, look no further than the Sea Hunter Mark II. In Addition to providing standard discrimination, the Sea Hunter Mark II boasts a unique Discrete Elimination mode which enables it to discriminate unlike any other PI manufactured. Gone are those pesky pull tab signals when you’re trying to find rings. The Sea Hunter ignores a lot of trash that plagues conventional PI detectors and can find treasure at depths other submersibles can’t reach. Good to 200 feet!

Garrett Sea Hunter Mark II Metal Detector

 

Sea Hunter LogoSea Hunter FaceFor over fifteen years, beachcombers and professional divers have chosen the Garrett Sea Hunter Mark II Metal Detector as their go-to device for treasure hunting under the water. Since its introduction over a decade ago, Garrett has continuously upgraded the Sea Hunter Mark II to include the some of the most advanced features found in an under water metal detector.

The sturdy construction of this device is built to take the rigors of ocean and sea metal detecting while being comfortable to use with a mounted hip and a long stem. The stem can adapt to any sandy, salty, or wet environment with four different stem configurations including the long stem stem with top, hip and under cuff stem mounts as well as the short stem ScubaMate for underwater searches. It's so sturdy that it can detect in depths of up to 200 feet below the surface!

Sea Hunter UnderwaterWhat makes the Sea Hunter Mark II stand out is its Pulse Induction technology that allows the device to ignore iron and salt water mineralization. In fact, the Sea Hunter Mark II is the only Pulse Induction metal detector that can disregard the appearance of pull tabs, foil, mineralized ballast stone and some iron while still being overtly sensitive to coins and rings. It eliminates trash by using through Standard BI discrimination and Garrett's exclusive Discrete Trash Elimination Mode.

10x14 Search CoilTo get the best out of the Sea Hunter Mark II for underwater metal detecting, Garrett recommends the Super Deep 10" x 14" Pulse Induction Coil. This search coil was designed by Garrett to detect in depths up to 200 feet. It is perfect for finding coins, rings and other treasures. The best part is that there are no special connectors or tools needed to attach it to the Garret Sea Hunter Mark II. Just plug it in and go!

Sea Hunter GraphThe graph depicted to the left displays the typical responses from metals in both trash elimination modes. Setting the Sea Hunter Mark II to a discrimination setting of eight, all metals above Nickels in Standard (Std) mode and above Pulltabs in Discrete (Dis) mode are detectable. This demonstrates how the enhanced power of the Sea Hunter Mark II rejects and eliminates trash while still being able to detect good targets.

    • ★★★★★ Got some extremely good hits!

    Review by Chris on February 27, 2020

    Garrett Sea Hunter Mark II metal detector is a very good machine! You have to take time to understand the readings. Took my machine to South Beach Florida, which they have Sugar Sand, and was very hard to dig up. This metal detector did its job like it was supposed to do! Got some very deep hits!
    • ★★★★★ Hard to beat

    Review by antigrav1117 on August 28, 2019

    Easy to handle in the surf- slices through the waves. Very sensitive PI detector- deep! Click and hunt! I use it exclusively in the surf, the robust design holds up well. I hip mount it on a dive belt, and use little stainless belt position clips to hold it where I want it. DF has a bigger head- but it floats on you! Plus.. it has much more resistance in the water (they sell a weight for it - even more drag) I may never move past a sea hunter for all round deep, fast, easy to use surf and dive detector.
    • ★★★★★ Great

    Review by Skid on August 22, 2019

    • ★★★★★ Love the 150

    Review by Al on August 21, 2019

    This is my first purchased detector and I love it. It is very easy to use.
    • ★★★★★ great beach and salt water machine.

    Review by James Ziel on August 20, 2019

    Waterproof. Easy to use? Gold and silver rings jump out at you. Dry sand. Or chest deep water. Great machine. Oh by the way. Coin shooters and relic hunters if you a beep and dig guy as I am. This is your machine as well. Gold prospector? This is it. Ive found pickers with this on my land in the north Georgia mountains. Bottom I live a block from the beach in Panama City Beach Florida. I have land in the mountains. This is a go anywhere. Do anything machine.
    • ★★★★★ Best Under water detector

    Review by Sandi on August 20, 2019

    I love the Garrett Sea Hunter Mark II Metal Detector because it is so easy to use. In the past I have used my friends under water detector and found it difficult to use and adjust and didn't really find much due to irregular signals. The Sea Hunter gives nice strong signals in fresh water and salt water alike. I found my first diamond ring using this detector. It is so sensitive it picked up part of a tiny gold chain too. And guess what. The price is a whole lot less than others I have used and the results were better. I highly recommend this detector to anyone who wants to detect the beach or water.

    Review by Mike G on March 29, 2016

    I must say this metal detector is one of the best on the market for the money. It is very easy to use and sensitive to gold. It is quick to setup and great for SCUBA divers and land users. I highly recommend this detector.
    • ★★★★★ One of Garrett's Best Detectors

    Review by Aenon J on March 16, 2015

    Garrett Sea Hunter Mark ll is one of my favorite machines. I have found a lot of rings, knives and clad over the years I have hunted with it. It is a deep PI detector. I will tell you I had to dig to China to uncover someone's case of beer they buried. My two best finds with it so far are a 10k 10 diamond wedding band worth $1600.00, a switchblade knife appraised at $230.00 and several other gold and silver rings and jewelry, along with lots of clad. I love my Sea Hunter.

    Review by Robert S on August 22, 2014

    Just received it last week, I absolutely love this detector. Water proof yes, Intend to SCUBA with this item. Tried it out on local beaches, WOW! This thing finds absolutely everything that has trace metals. Also it rings out loud and clear. I'm not a deep digger but this thing might change my mind. I've had multiple deep hits that I gave up on after approx. 12" - 18". Can't wait till my beach scoop gets here. This machine is over the top. Superior value.
    • ★★★★★ Happy with It

    Review by Jim O on January 14, 2014

    I bought this TYPE of detector because I like to scuba dive and expect it will be a fun hobby. But initially I bought it because I needed to find two property pins that were set in the early 70's in an area with some very heavy vegetation. The cost of pin location was $150 per pin by a "professional service" and I found them both within an hour! Finding these two "missing pins" allowed me to then lay in the boundary lines with a compass and saved me another $400! So now I've already recovered 1/2 of what I spent on the detector (pins alone) and still have it to explore UW treasure hunting! It seems well built and worked great for my limited usage. I'll write another review when I've had more time to dive with it. No telling what you might find under the docks of a marina if you can get permission to look!

    Review by Tom R on December 23, 2013

    Had many Garrett Detectors over the past 45 years (BFO FIRST). All were great detectors. Now I have the Garrett Sea Hunter and AT Pro. I use the Sea Hunter mainly for the beach, it is the best and can't be beat. Do you ask how deep is sometimes too deep? 10-14 inches for a paper clip today 12/18/13 and 23 coins. It is built like a tank, made of real metal (lol). I also carry the Ace 350 in my car at all times, you never know.
    • ★★★★★ Great Machine - Be Patient and You Will Be Rewarded

    Review by Ron C on November 4, 2013

    In my experience the machine is at its best when operated with zero discrimination. What that means is you will dig every target - which is a great deal even on so called "clean" beaches. So be prepared to dig sparkler wires, bits of zippers, single staples. BB sized metal, etc. Also be prepared, if you are careful enough and diligent enough, to recover targets as tiny as stud earrings. I recovered a tiny stud that took five minutes to find in the scoop sand when dumped on the beach - it was recovered in the rolling surf and was at least six inches down. This target came up so loud if it had been one of my land machines I would have thought it was a pound of can slaw. There were lots of other hunters on the beach that day using Minelabs, White's and all the usual suspects. But I found this target. Now let's be honest, I've hunted for a long time enough to know there is a high degree of luck - you have to pass over the "right" target. But everyone in my hunting club agreed there are few machines that could have detected a target with so little metal - they agreed so much my group jewelry find took second place at our last meeting. You decide - Minelab and all the other machines are for sure superb - look at your budget be honest with how much you want to dig and then take the plunge. I am a detectorist at heart so the more I dig the happier I am. Best to all.

    Review by Kent W on June 17, 2013

    I bought the Sea Hunter to hunt the beach. Set it up and hunted 3 nights for about 4 hours each night. The water was real rough so I didn't get to test it in the surf much. Found lots of bottle caps, tent stakes, and other iron trash. I set the discrimination at zero, anything above that it wouldn't pick up small gold rings. I like the detector but wish I'd waited and bought a higher priced machine. You will do a lot of digging with this detector. For the price I'm happy with the product. I found a cheap toe ring the first night out, a silver plated ring the second, and a pair of gold earrings the third. I averaged about 250 holes a night. I like the detector, but wish it had more tones.

    Review by Elwyn H on March 19, 2008

    I like to search in the water for rings with my Sea Hunter Mark II. I have over 20 different detectors. I started around1973 and will do it until I can't anymore. It is one of the best hobbies there is. As far as the use of the Sea Hunter I like it very much. It is very easy too set up. You don't waste a lot of time re-tuning. It runs very steady. It paid for itself the first time I used it. With the price of gold skyrocketing I plan on doing a lot of searching this summer. On a typical day I can find 100 to as many 500 coins, 1 to 20 rings and who knows what else. I have found over 300 diamond rings in the past 35 years and hope to find a few more.

    Review by Michael W on March 19, 2008

    I will start off by saying I'm new to this machine but I like what I see so far. When I started metal detecting I wanted a water machine so I purchased the Fisher 1280x and quickly discovered it was not that great for salt water hunting. I love it in fresh water and dry sand but in salt water it gave off too many false signals. So I traded the Fisher in for a Garrett Sea Hunter Mark II. I've only had this machine for a few months and it has been pretty cold here in New Jersey so I only got it out once. The control box is pretty easy to use. This is my first Pulse Induction machine so there is definitely going to be a learning curve. Although I did not find any gold or silver the first time out I was able to find some clad so I know it works.

    I did play around with the trash elimination knob but I did not see a big difference. I've heard that it is really hard to get any discrimination with a pulse machine so I was not really surprised by this. Although it could be more from being a new user of the unit then because of the unit it self. I like the fact that you can use three different set ups since the control box attached to the shaft, a hip mount option or the scuba diving set up with a short shaft. I really look forward to getting out there a few more times and seeing what this machine can really do. Since I'm still learning this machine I would not recommend it at this point but it does seem like a pretty flexible machine depending on what your water hunting needs are.
