Underwater metal detectors are great for finding different metallic objects hidden beneath a thick layer of sand or even shipwreck. Nowadays, underwater metal detectors are made in various different shapes and sizes however; they all come with a handheld electronic device that has the ability to pick energy reflected from the surface of metallic objects. Normally, the signal gets much louder and higher in pitch when the detector comes closer to the metal object.

How does the underwater metal detector work?
The underwater metal detector works by containing an oscillator that produces the alternating current which then passes through the metal coil thus producing a magnetic field. Therefore, when the underwater metal detector reaches an object made from metal, the eddy current will become induced with the metal thus producing its own magnetic field. The metal is detected because of the change in the magnetic field that occurs when the metal detector comes closer to the metal object.
When was underwater metal detector invented?
Metal detectors were invented back in the 1970s but then they were mainly used for industrial and marine purposes only thus not many divers had them. Regular land metal detectors were even used to find and locate land mines that were left after the Second World War as well as look for hidden weapons such as bombs, knives and guns hidden in walls or the ground.

Why an underwater metal detector is needed?
Metal detecting is a hobby of many divers and even fishermen that enjoy scouting and searching for a new location that might contain some priceless artefacts beneath the ocean floor. Moreover, there are even whole clubs and groups that plan and go out to sea on search missions for gold, old coins, war equipment and fallen soldiers neck tokens.
In the 1980s a lot of divers recovered many neck tokens of American soldiers perished in the Vietnam War thus this way they could pass them on to their families. Furthermore, for successful metal search mission, you will need to select a durable underwater metal detector that will stay in contact with the magnetic field at all time and will have excellent location tracking.
But, remember that a regular metal detector on its own is usually useless hence you will have to purchase several other pieces of equipment such as diving goggles, headphones for the metal detector and some type of scuba suit because ocean water tends to be very cool even in the summer especially at great depths.
Moreover, keep in mind that underwater metal detectors can be made from different materials such as fiberglass, plastic and even BPA material. However, most modern models of underwater metal detectors are made from carbon, metal or fiberglass as these metal detectors are far more durable and reliable.
How to choose a good underwater metal detector?
Nowadays, there are many different types of underwater metal detectors including metal detectors made out of plastic, carbon and even metal. Moreover, you can find underwater metal detectors made in different colors plus you can also find different shaped handles thus you can be sure you will find just the right one for yourself.
Furthermore, these underwater metal detector handles can vary in weight and can range between 1/60th of an ounce and up to a whole pound for large underwater metal detectors designed for deep water search. Considering that there are so many different types of underwater metal detectors that some individuals could even get confused.
However, before you panic remember that the most common underwater metal detectors are made from a combination of metal and plastic.
If you are just planning on starting to look for artifacts and treasures with an underwater metal detector then you might want to go for the shorter and lighter models until you will be sure of your skills and desire to continue with the hobby. Furthermore, give preference to models that are made with anti-rust and corrosion finish as such metal detectors will last much longer and will be perfect for salty water.
Also, see if the underwater metal detector of your choice comes with a carrying case that you can use to store your metal detector when it will be not in use, for example, in winter or when you travel abroad for work or leisure. A carrying case can protect the metal detector from scratches and scuffs plus it makes transporting the metal detector much easier.
Lastly, if you intend to use the underwater metal detector in shallow waters then think about wearing waders and preventing them from slipping and filling with water. You could use a wader belt to keep the waders in place, these belts will be available in any specialized shop.
