Underwater Metal Detectors – Could it be a Scam?


Trouble-Free Methods For Waterproof Metal Detectors Described

Another thing to consider is the stock coil that comes with your detector. These machines will punch through ground minerals like salt and iron and will report on all metal objects without the ability to discriminate. ​Click here to read our complete guide on the best metal detectors for gold.

All metal detectors detect metal – just like all cars drive down the road. There’s no quicker way to become frustrated with the hobby than buying a complicated detector you don’t understand. review If no, then you’re probably going to want to start with an entry-level machine. This buying guide will go into detail on the best metal detectors and explain what to look for when choosing.

Therefore, you need prior experience in using metal detectors to get the hang of it. It is perfect for use in heavily mineralized ground and saltwater without the need to use special modes. Despite the fact that it is considered an entry-level package, it still has powerful features that allow it to search even in the most delicate places.

Pulse Induction (PI): A PI detector works by broadcasting fast electronic pulses into the ground one after another. A variety of both PI and VLF underwater metal detectors can be found on eBay. If you are interested in metal detecting, you may want to browse the underwater metal detectors available on eBay.

But you’re depth will be severely limited to the point where it’s not even worth it to detect. Most all round machines will do just fine for relic hunting. Frequency and depth have an inverse relationship, so the higher you get, the less depth you’ll get on coin-sized targets.

This is what makes it a truly dual function metal detector. Let’s take a look at the best underwater metal detectors available today. PI metal detectors work by sending short bursts of electronic pulses into the ground. It is quite common for “waterproof” products to just be covered in a sealant which until broken makes it waterproof, doing this you could make any product waterproof for a given amount of time.

So check the weight, you will probably want to use it on land sometimes, unless you want to buy separate models for land and for water. Regarding versatility, the added waterproof feature imply some extra weight related to buoyancy and water protection. They shoot bursts of electronic pulses into the ground and receive back a signal when they hit something metal. So regarding detection, you have very low frequency (VLF) detectors and pulse induction (PI) detectors. Oh, and Scott please correct me if I am wrong, but the detectors induce eddy currents in metals that they pass over, whereby creating additional current in the metal, thus allowing for the field detection, so if your ROV isn’t under the coil, there shouldn’t be any current induced.

A bag to carry your metal detector in, sand scoops and a sifter will all make treasure hunting easier and more fun. Most underwater detectors have a set of waterproof headphones with the metal detector. If you are going to use your metal detector near salt water, for example, you should plan to purchase a PI detector. In fact, you can use this type of metal detector for deep searches but should be aware that PI detectors are not very discriminatory, so you will hear pings for all metals and may be digging for a lot of trash as you search for treasures. Even experienced detectors will need some time to get used to a new metal detector before taking it underwater.
