Tips for detecting metal underwater

Shallow water treasure hunting can turn up incredible finds as long as you are willing to get adventurous and wet. The reality is that swimmers tend to lose coins, rings and, most important, valuable jewelry that is simply waiting to be found. Treasures that are lost on the beach are equally important, but you will not come across them before the tide. If you are genuinely ready to take the plunge and invest your hard-earned money into an underwater metal detector, then you need to make sure that you find the best gold and whites finder for your needs. Besides an electric instrument in your possession, some metal detecting tips may come in handy in the pursuit of treasure.

Metal detector technologies for underwater use    

There are two major types of water proof metal detectors as follows: Pulse Induction and Very Low Frequency. Pulse Induction metal detectors transmit a series of electronic pulses into the ground and they are in no way affected by salt and ground minerals, which will allow you to find highly sensitive metals. A pulse detector is best suited for salt water beaches and diving. On the other hand, Very Low Frequency metal detectors are sensitive to coins, gold and relics. They have the added capability of discriminating out junk while at the same time accepting good items. As opposed to Pulse Induction finders, these ones come equipped with sensitivity adjustment and ground balance control.

Underwater metal detecting activities

Broadly speaking, underwater metal detecting refers to one of the following activities: snorkeling with a metal detector, scuba detecting and shipwreck diving. Snorkeling with a metal detector means hunting for treasure using a snorkel and a diving mask. This particular activity does not require strength or equipment. Scuba detecting involves metal detecting in fresh and saltwater less than 20 feet deep. Last but not least, shipwreck diving includes treasure hunting in the area surrounding a shipwreck as well as looking for precious things inside the sunken ship. It is the most costly activity since it requires the use of expensive equipment.

How to snorkel with a metal detector

Due to the fact that snorkeling is the easiest type of underwater activity, we will focus all our attention of it. In order to snorkel with a metal detector, there should be at least a few feet of visibility underwater and snorkeling should be done at water depth ranging from chest-deep to above your head. Pay close attention to the valleys, low spots and around the rocks on the bottom because they are the places that gold possessions occupy. When in sand less deep than five inches, swing the electric instrument in a semi-circular motion right in front of you. When in deep sand, slow down the movements and listen for low beep signals. For gold targets, you should use zero discrimination and maximum sensitivity. Some snorkeling treasure hunters work with long steel trowels to recover targets form the clay bottom. You can use the long trowel to fan the water when you almost reach the target because the hydraulic action will preserve your find.
