Plus, each model works just as well on dry land as underwater. It is more suitable for fresh water than salt water because its ability to detect small gold comes with the cost of being reactive to saltwater’s conductivity. Furthermore, it has a fast recovery time, allowing the detector to be more efficient. Furthermore, AT Gold has an iron audio feature, which can be used in any of its three detecting modes. For underwater detecting this is very nice, because you can be more selective with your digging.
The underwater metal detector is a valuable tool for the Underwater Crime Scene Investigator. GO METAL DETECTING ANYWHERE YOU WANT: Our waterproof detector coil will help you go relic hunting in your back yard, garden, park or even take your metal-hunting skills to the beach. In 2014, it was named the #1 underwater metal detector by an independent study performed by the U.S.
The pulse induction technology provides plenty of depth, plus the various adjustment settings allow you to customize performance to the environment. There is a dial for depth, for example, which adjusts the pulse width.
On top of everything this metal detector comes with a lifetime warranty. At 2.2 pounds, this is the lightest metal detector we tested. One of our technicians brought in a similar piece from another metal detector, and we were able to test. We have to include the fact that this metal detector arrived at our lab missing a piece of the arm. This metal detector was easy to assemble and didn’t require a screwdriver or any other tools.
Aside from that, you can also use this device in fresh and salt water. As such, you can use it for hunting in shallow and deep water. The Fisher CZ21-8 can be submerged in water up to a depth of 250 feet. Bounty Hunter also equips their metal detectors with a preset ground balance that neutralizes the response to mineral content in the ground. This model also comes equipped with headphones and 1/8″ headphone jack for privacy while treasure hunting.
Its price is not too high you can buy this wonderful device in the range of 500$ to 700$. Its depth range is 250ft and has a battery life of 75 hours and I think https://metaldetectorshub.com/underwater-metal-detectors/ it’s enough. It’s result and accuracy is 100% if you talk about on ground performance it Best and if you talk about the undersea performance it’s more than Best.
You are looking to spend almost half of that, a lot of people that I’ve previously helped with underwater detecting actually owned the AT Pro before due to its strength at detecting on land also. The 250′ maximum depth means it’s great for diving, while the sensitivity adjustment, manual ground balance and discrimination settings allow you to fine-tune the performance for both saltwater and freshwater environments. As it’s a pulse induction detector, the Sand Shark is great for hunting in wet sand and saltwater environments. Aside from the discrimination function, the Sea Hunter Mark II comes with several search modes, including Non Motion ,All Metal and Standard PI Discrimination. If you’re looking for a pulse induction detector for diving, the Garrett Sea Hunter MkII is my top pick.
The disadvantage is that, this method can produce high amount of false responses due to changing ground conditions. Ground balance is not necessary in discrimination mode, however, this method may have the disadvantage of reducing detection for low conductivity items. With the Garrett ATX, the level can be set to 3-7 and most of the responses will be eliminated in salt water conditions. With the Garrett ATX, there are three ways to operate underwater, the first being the discrimination method. Even if you aren’t fully submerged, you can use these detectors safely knowing that an accidental slip into the water isn’t going to ruin their electronics.
