Which Waterproof Metal Detector Is Right For You?

Waterproof Metal Detector

If you want to take the plunge and dive in to the murky waters of underwater metal detecting, then you already know you’re going to need a waterproof metal detector. Before you fork over any cash, you need to consider several options. This article will help you decide which waterproof metal detector is right for your treasure hunting.

First, you should know the difference between three main types of waterproof metal detectors. These are Pulse Induction, Very Low Frequency and Broad Band Spectrum.

Pulse Induction (PI) metal detectors emit rapid electronic pulses that are not affected by ground minerals or wet salt sand, so they are ideal for diving and for salt water beaches. They are highly sensitive to precious metals, but do have a low level of discrimination between them and junk items. PI detectors are deep seeking, and work extremely well in areas with challenging ground mineral conditions.

Very Low Frequency (VLF) metal detectors are very sensitive to jewellery, coins and relics and can better discriminate between junk targets and precious ones. Ground minerals do affect them, but most have ground balance controls and sensitivity adjustment.

Broad Band Spectrum (BBS) metal detectors emit multiple frequencies of signal at the same time. Usually BBS detectors transmit from 1.5 to 25 kHz at once.

Now, ask yourself where you will be hunting. Will your waterproof metal detector be your primary detector, or will you use another one for hunting on land? Will you be using it in fresh water, or in salt water primarily? If you want to use your detector in salt water, then you are best off with either a BBS or a PI detector, although some VLF detectors do have a salt water mode. All will work in fresh water.

Will you be treasure hunting on dives? Make sure you check the depth rating on your waterproof metal detector, and that it meets or exceeds the depths you will be diving to. It is better to err on the side of caution here, and get one that is rated for deeper than you intend to go. Also, for diving and for snorkeling, be certain to get a model that includes a short dive pole, as this will make it much more comfortable to use.

There are also some basic accessories that will make your watery hunts easier and more convenient. A carry bag will not only protect your waterproof metal detector, but make it easy to grab and take with you on a moment’s notice. If you will be hunting along the beach, you will absolutely need a trowel and several sand scoops. A sifter scoop is a must-have for prowling through layers of sand. And, of course, you will need headphones. Most waterproof metal detectors come with waterproof headphones.

When you are ready to buy a waterproof metal detector, be sure to let the seller know what sorts of items you intend to search for, and where you will be doing it. They will then be able to give you further advice, and hopefully some first-hand experience with one or two models so you can make an informed choice. So dive in, and happy hunting!
