For centuries, boats and ships filled with huge amounts of treasure have sunk to the bottom of the oceans and lakes. Due to the technology of past years, rescue missions were not possible. In addition, diving to those great depths for long periods was not feasible. As a result, most of the valuable treasure lay at the bottom waiting to be discovered.
When choosing a metal detector for using underground, one of the key considerations should be weight. The heavier the detector, the harder it will be to move around underground. While weight may not much of an issue above ground, it means a lot under water. Good underwater detectors come at very low weight.
Coil Sized Metal Detectors
Another important feature of underwater metal detectors is coil size. If one is hunting for objects underwater, they need to be able to detect objects that are buried under layers of sand. In such an instance, a huge coil will prove quite effective. However, it is important for one to determine what types of objects they are searching. In most cases, searching for treasure underground means one is looking for huge objects. This means that an underwater detector should have a huge coil.
Water Proofed Metal Detectors
Underwater metal detectors need to be water proofed. The waterproofing should be preferably for huge distances under water. If the detector can only operate in shallow water, it may not be of much use. This is because when it is bombarded by a wave, the weak waterproofing will give in and flood the essential equipment. A good detector is also made of stainless steel material (as an expert discusses about top underwater metal detectors on the following piece; http://www.metaldetectorjudge.com/best-underwater-metal-detector-in-2015/). Otherwise, it will only be usable for a few weeks before it becomes too corroded to be of any use to anyone.
In order to become effective at detecting for valuables underwater, one needs to have solid data behind them. One of the best ways to do this is to peruse through historical records. This can give one insight into important shipwrecks that may have gone unnoticed for years. One should also make sure they join a good metal detecting club in their area. This will help one to hone their skills in metal detecting.
Besides ancient records, areas frequented by tourists are a good place to go metal detecting. This is because tourists tend to be very well off. If they can afford to take a holiday that means they can afford to buy expensive valuables. This is usually a good place to target. Due to the high tide, that means that some of the valuables may have been swept out to sea. However, due to their weight, they sink to the bottom only a short distance offshore.
Choosing a metal detector should also involve cost considerations. If one is going to do this only for fun, a cheap model will do just fine. However, if one is following a good lead on a potential treasure, finding the right detector could be of great importance. That will mean one has to spend a bit more.
