Another low priced metal detector that is worth investing in is this starter set from INTEY. Buyers that opt to purchase the starter kit get the base metal detector plus headphones, a carrying bag, pinpointer and pouch/trowel combo kit. This is the best introduction to metal detector use on the market, and although it is made for kids/juniors, adults can still get a lot of use out of the set. This low priced NHI metal detector starter kit is marketed towards beginners that want to learn the ins and outs of the craft. What happens when you introduce a metal detector to a wet surface?
Unlike the ATX and SDC, the AT Gold is a very-low frequency (VLF) detector. With Adjustable Ground Blance Window, the detector ground balances properly and smooths out the ground signals, thereby allowing the user to hear the deeply buried targets. The smoothness of the threshold on the SDC 2300 is ideal for underwater hunting to eliminate the need to dig false targets.
The pulse induction technology ignores ground mineralization, so it’s perfect for hunting in saltwater or ground with heavy mineralization. This makes it suitable for shallow water hunting, but not for diving.
Fitted with near neutral buoyancy coil which makes diving that much easier, you can imagine you don’t want to be fighting to keep your detector afloat and at the same time, you don’t want it to plummet. Most retailers that sell metal detectors stock underwater models – at least those for shallow water hunting.
Many devices out there claim to have this functionality but tend to be only semi-waterproof. Balance – Metal detectors that don’t balance out their weight will either be bottom heavy or top heavy.
If searching an area on an arc search pattern, the diver can start off searching by hand and then re-search it with a metal detector. In normal condition an,d solid bottoms, I prefer using a metal detector underwater only as a backup to a diver who is searching by hand. Emergency responder agencies that consider purchasing handheld underwater metal detectors should carefully consider each product’s overall capabilities and limitations in relation to their agency’s operational needs. This is why dedicated gold hunters often purchase a special metal detector designed to “listen” specifically for smaller gold fragments. If you’re to search private property with your metal detector, the owner of the property must first give permission.
The searchcoil should be held off the ground or bottom approximately two inches. This is important in searching for metal items that might be found around a crime scene such as bullets, keys, jewelry, etc.
This model from Garrett has a Discrete Trash Elimination mode, so you don’t have to spend too much time digging through trash. One reason is that you can use this detector with both short and long stems, plus it also comes with straps for wet suits. Lastly, there is a precise pinpointing and VCO option in this device that enhances precision while you hunt.
Significant Criteria In Underwater Metal Detectors – Some Thoughts
You can put Sea Hunter Mark II up to 65 meters deep into the water. Two signals VLF (5 or 15 kHz) that penetrate deep provide twice more information for the target identification. When comparing their functionality, Infinium works using 96 frequencies which ensures faultless work both in brackish and fresh water. If you compare the device with Minelab flagship device, the latter is 1.7 kg heavier; you can drown it up to 60 meters deep. You will also get a DVD disk with a manual to simplify and speed up the process of mastering the device.
The claim-to-fame of this pulse induction detector is it’s ability to ignore minerals in the environment while maintaining high sensitivity to all metal targets. With a 200 foot depth rated housing and a 6 foot maximum detection range, the Pulse 8X is Fishers top of the line detector. The new metal detector line was developed for the active outdoors enthusiast to enhance the possibilities of outdoor activities. The American Antiquities Act of 1906 and the Archaeological Resources Protection Act of 1979 made it illegal to use a metal detector in national parks, monuments, beaches, or Civil and Revolutionary War battlefields. There is, however, some legislation that limits metal detecting on federal land, Native American burial or holy sites, and historical sites.
Because of their high sensitivity, a good VLF metal detector will separate junk metals from target metals once you’ve adjusted the ground balance to prevent interference from mineralized soil. You’ll also need to consider whether you need a scuba diving metal detector or one for hunting only in their website the shallows. But the best waterproof metal detector will allow you to submerge the unit to a depth of up to 200 feet. Just because a detector is advertised as “waterproof” doesn’t mean it’s suitable for underwater hunting, while a “submersible” detector isn’t necessarily built for diving.
