Do you enjoy going scuba diving? and do love the experience of underwater treasure hunting? Looking to going scuba diving at the beach and hunting for treasure could not be made easier if you have just the right tools for detecting those tiny metals at the bottom of the water. Metal detecting under the water can be a lot harder than on the ground but bear in mind that your chance of spotting your little treasure can be higher than your chance on the ground since not many people would go underwater to hunt treasure. Hunting for precious metal under the water needs more than just a highly sensitive device to metal, especially for saltwater, since it needs to go deep under the surface of the water and to distinguish between wet sand, ground mineralization, and actual metal you are trying to find. So, if you are trying to find the best underwater metal detector, you might need to consider our recommendations on our list of top 10 underwater metal detector you will ever need!
Very Low Frequency (VLF) sensitivity: A good underwater metal detector has to be highly sensitive to the tiny and thin metals under the water. You may also need to consider the type of water you are hunting in. For a high sensitivity metal detector, it has a very low frequency (VLF) feature that allows the hunting for treasure a lot more effective if you are hunting in freshwaters like lakes, rivers, and other water bodies.
Pulse Induction (PI) ground resolution: if you are out to hunt in saltwater, the best feature that you may need to find when you purchase your underwater metal detector should be its pulse induction resolution points. The reason that the PI technology of the underwater metal detector probably works the best for saltwater is that the PI detector can be highly unaffected by the wet sand and the ground mineralization under the water.
Weight: besides the quality of the good detector, another feature you might go for is probably the weight of the detector. You might not want to go hunting and came back tired with just carrying your metal detector.
