If you're diving in to underwater metal detecting, then you definitely need a waterproof metal detector. Listed here are some things to think about before you settle on a model.
First, you must know the distinction between the three principal kinds 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 fast electronic pulses, are deep seeking and are very sensitive to precious metals although not very discriminatory between them and junk items.
Very Low Frequency (VLF) metal detectors discriminate better than PI detectors and are great for locating coins, relics and jewelery. They are affected by ground minerals but 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 these kinds of waterproof metal detectors will work in and around fresh water, but for salt water you will want either a PI or a BBS detector.
If you'll be diving, ensure you get a waterproof metal detector that's rated for the depths that you simply intend to dive. Better to get one rated for deeper depths than you suppose you'll need. Additionally, make sure it has a short dive pole, so it is more comfortable to make use of while snorkeling or diving.
Additionally, you will want to get some accessories that will make your overall water hunting simpler and more convenient. A carry bag offers protection, and makes it straightforward to grab and go everytime you want. For beach hunting, a trowel and sand scoop are essential. make sure to get a sifter scoop for simpler sifting through layers of sand. headphones are another should-have. The majority waterproof metal detectors include waterproof headphones, however it is always good to have extra.
Whenever you're buying your waterproof metal detector, let the vendor know what kinds of targets you will be on the lookout for and the place you'll be doing all of your hunting. They are going to be able to advise you in deeper detail about features and capabilities you could need to have, and provide you with some first-hand field experience 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'll get a detector that may bring you hours of enjoyment, and hopefully some great treasure!
