If underwater treasure hunting is something you want to get serious about, and whether you’re upgrading or buying your very first detector, you’ll find a lot of great information about the features of each. Some waterproof metal detectors will allow you to search in water up to ten feet (three metres) deep. A saltwater metal detector can be used in sea water or fresh water.
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.
As for the sound identification – the device has a mute mode and adjustable threshold tone. There is also a function to test the batteries charge, which is very convenient; of course – nobody would like to find out that the batteries are low after 15 minutes of deep diving. In this case you can remove the middle shaft and make the device smaller sized and more convenient to use. Application of this technology allows Garrett Sea Hunter Mark II get an immediate target response.
You will f,ind a high quality underwater metal detector at an affordable price from brands like KKMOON , SMART SENSOR , TIANXUN , MiLESEEY , shrxy , HOOMYA , VOKPRO , JinYinBiTan , SGF SUPER GOLD FINDER. Barska Premiere Edition Underwater Metal Detector features 100% submersible metal detector and works in fresh or salt water up to 32.5 feet (10 meters). The Premiere Edition Underwater Metal Detector by Barska is used to detect metals in fresh or salt water up to 32.5′.
Which means that a waterproof metal detector is a device capable of functioning both on the ground (moreover, it was designed for this) and under water at insignificant depth. I’d really recommend an getting yourself the best underwater metal detector if you are spending lots of time in or near the water. This underwater metal detector is a Pulse induction machine, so it can work on dual frequencies, which are 15kHz and 5kHz.
In a worst case scenario, a strong current could knock the stem apart from the coil. Headphones in particular are needed when working in water areas due to the amount of activity. Having support for it is a big plus and keeps you from damaging the product. As a result the control panels for both types are a lot less cluttered than other metal detectors.
It’s important you do your homework when buying a device you wish to take underwater. We reviewed the Garrett AT Pro in depth a couple of months ago, mainly because we simply love this device. The drop in battery, headphones and removable pole all included as standard, make the Tiger Shark a cat like fish you should seriously consider in your search for the very best device which will suit your needs. Ignoring small pieces of trash via the trash rejection control the detector converts to a belt mount, with the impressive waterproof headphones included as standard. As with most devices in the waterproof category it really isn’t a machine for beginners, with many buyers stating the learning curve was steep.
To get the distance an penetration you are looking at, I think a traditional metal detector might be a bit short. The OpenROV community hasn’t delved into metal detector payloads just yet, but it is certainly one of my eventual requirements for a project. The P8X comes with everything you need to search both on land and submerged to a depth of 200′. I’m sure none of these are good, but I’ve never even used a metal detector before.
If you want to primarily hunt underwater in salty conditions I’d recommend a PI machine. In the red corner: A pulse induction machine finds deeper, smaller objects than VLF detectors and they’re programmed to ignore ground minerals. A good ground balancing VLF machine will ignore mineralized soil and you’ll be able to pick out the treasure rather than a rusty nail. To hunt for underwater treasures your machine needs to be waterproof and if you’re heading to the ocean it must be able to handle highly mineralized saltwater conditions. A handy, if not essential, feature of the Pulse 8 is that it has slightly negative buoyancy – so feel free to dig up a target without your machine floating off in the current.
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 metal detector waterproof coil 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.
