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. It detects metal 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. However, then they were mainly used for industrial and marine purposes only. Not many divers had them. People even used regular land metal detectors to find and locate land mines.
This was very important in case of mines that were left after the Second World War. People also used these to look for hidden weapons such as bombs, knives and guns hidden in walls or the ground.
Why You Need an Underwater Metal Detector?
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 best 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 best underwater metal detectors are made from carbon, metal or fiberglass. Therefore, these metal detectors are far more durable and reliable.
How to Choose a Best Underwater Metal Detector?
Nowadays, there are many different types of underwater metal detectors based on material. For example, 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.
Conclusion
If you are just planning on starting to look for artifacts and treasures with the best 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. Such metal detectors will last much longer and will be perfect for salty water.
