Underwater treasure hunting can be an interesting pastime and underwater metal detectors help you to carry on with your hobby. These are waterproof devices and are designed in such a way that they can be used in shallow as well as in deep waters. With the help of these detectors, you can recover relics, rings, coins, jewelry and many other things.

Underwater metal detectors are typically made so that they can hunt in saline waters as well as in fresh waters. Underwater metal detecting is a hobby which helps you to relax and unwind when you are floating underwater and trying to locate relics. But to be successful you need to buy the right metal detecting equipment.

Types Of Underwater Metal Detectors

There are many types of underwater detectors and each of them comes with some special features. Pulse induction detectors, very low frequency detectors and broad band spectrum detectors are used for the purpose of under water metal detecting.

A Little Elaboration On The Types Available

Pulse induction detectors transmit a series of electronic pulses to the water. These pulses do not get affected by the water, or sand or the minerals that are present underneath. But they are sensitive when it comes to metals. This type of detector works best on saline water beaches and while diving. The pulse circuit goes very deep inside the water. The ability to discriminate precious objects from trash is limited in this type of underwater detector.

Very low frequency detectors generally function within 3 - 30 kHz range of frequency. This type of detector is sensitive to coins, relics and jewelry and has the ability to separate precious items from trashy items.

But unlike pulse induction detectors, the very low frequency detector is influenced by the minerals in the ground. These come with sensitivity adjustments. These are also equipped with a ground balance control. You can customize the device so as to minimize signals that are caused by vibrations produced by the underwater minerals.

Broad band spectrum underwater detectors transmit signals in multitudes of frequencies simultaneously. Broad band spectrum transmits 17 frequencies together. They range from 1.5 - 25 kHz.

You can use these underwater metal detectors while strolling along the beach, or when you are wading in water which comes up to your waist. If you are a diver, you can venture in deep seas and with these detectors, you might even locate remains of shipwreck. The chances are good that you will end up with precious, antique relics with the help of these underwater metal detectors.
