Underwater or places near salt water metal detecting offer a fine treat of treasures. But that kind of hunt will need a special type of metal detector and not just any kind of waterproof metal detectors. You see, there are three different types of waterproof metal detectors. These differ on their pulse induction, low frequency and broad band spectrum detectors that are used for underwater hunting. The pulse induction or PI underwater metal detectors are recommended for use in and near salt water. The PI's electronic currents are strong enough to get through the ground minerals. They are not as accurate when it comes to reading, and you may have to go through finding some trash before you locate your sunken treasure. Garret and Headhunter are both brand names that you can count on for a good underwater handheld metal detector. These metal detectors are guaranteed to withstand the salt water and may be submerged in it as well. Very low frequency or VLF underwater metal detectors, unlike PI underwater metal detectors are able to pick out what is sunken treasure or trash. The VLF is affected by the mineralization in the ground. Fisher and Headhunter are recommended brands for this category. For the third kind of underwater metal detector, broadband spectrum detectors have several frequencies that they transmit as rather than just one. BBS detectors give greater and more accurate discrimination. This kind of detector provides a greater depth than other underwater metal detectors too. If you are still left undecided on what underwater metal detector to buy, consider where you live. Suppose you live near the beach, you'll need a metal detector perfect for salt water. If you plan to go metal detecting by the lake that has fairly a great depth, without thinking twice BBS is most compatible for that. Always consider what is regarded as important before purchasing a metal detector. It's the rationale for your success, happiness and comfort ability in a metal detecting trip. After a few hunting sessions you will definitely know what other things you need for you experience to be more worthwhile and adventurous.
