If you're diving in to underwater metal detecting, then you want a
waterproof metal detector . Here are some things to consider before you decide on a model.
First, you must know the difference between the three primary sorts of waterproof metal detectors.
Pulse Induction (PI) metal detectors are great for diving and salt water seashores, since they don't seem to be affected by ground minerals or wet salt sand. They use rapid electronic pulses, are deep seeking and are very sensitive to precious metals though not very discriminatory between them and junk items.
Very Low Frequency (VLF) metal detectors discriminate better than PI detectors and are great for finding coins, relics and jewelery. They're affected by ground minerals however most have controls to overcome this.
Broad Band Spectrum (BBS) detectors use simultaneous, multiple frequency signals and are very sensitive overall.
Where will you be treasure hunting? All of all these waterproof metal detectors will work in and round fresh water, however for salt water you will want either a PI or a BBS detector.
If you may be diving, ensure you get a waterproof metal detector that is rated for the depths that you intend to dive. Better to get one rated for deeper depths than you suppose you'll need. Additionally, be sure that it has a short dive pole, so it's more comfortable to use while snorkeling or diving.
You will also want to get some equipment that will make your overall water hunting easier and more convenient. A carry bag provides protection, and makes it straightforward to grab and go whenever you want. For beach searching, a trowel and sand scoop are essential. make sure that to get a sifter scoop for simpler sifting through layers of sand. headphones are another should-have. Most waterproof metal detectors include waterproof headphones, but it is always good to have extra.
If you're shopping for your
waterproof metal detector, let the seller know what kinds of targets you'll be searching for and where you will be doing all of your hunting. They will have the ability to advise you in deeper detail about features and features you may need to have, and offer you some first-hand field expertise with a number of different models. So before you dive in, do your analysis and know what you need, and what you don't. Then you will get a detector that can bring you hours of fun, and hopefully some great treasure!
