Underwater Metal Detectors

Hunting for treasures underwater can be a fun and exciting hunt. The Underwater Metal Detectors are all waterproof. Underwater metal detectors are ideal in hunting for precious metals, coins and relics etc both in shallow and deep waters. You will be sure to recover coins, relics rings etc that lie deep in water or along beaches. These products can be used in shallow waters too.

They do not discriminate on the nature of the water. Salty and fresh waters, the metal detectors will still perform. This hobby is quite relaxing since it allows you to float in water as you pursue your hunt. To make this hobby an interesting one, you need to purchase the right and quality metal detector.

Types of Underwater Metal Detectors

There are a variety of underwater metal detectors available in the market. Every manufacturer produces a distinct metal detector with unique features and designs. Most underwater detectors have these features.

• A pulse induction detector.
• Abroad band spectrum detector, which helps to detect metals underwater.
• A low frequency detector that gives a hint if the frequency available is worth working with.

A Little Elaboration on the Types Available

Most Pulse induction detectors transmit a series of electronic pulses to the water. These pulses are not affected by water. Neither are they affected by minerals nor sand present underneath water surface. However they are very sensitive when it comes to metals. This detector works best in salty water beaches and while diving. The pulse circuit is transmitted deep in the water and this detector performs pretty well. Nevertheless, it has a drawback. It is limited in its capacity to discriminate precious items from trash.

Low frequency detectors generally function within a 3 to 30 KHz range of frequency. These detectors are sensitive to coins, relics and jewelry. Moreover they have the ability to separate precious items from trash.

Unlike pulse induction detectors, the low frequency is due to the presence of minerals in the ground. They are well equipped with a ground balance control and a sensitivity adjustment. This detector is flexible. This flexibility allows a user to customize it to suit his or her needs. You can configure it to reduce signals arising from underneath water minerals.

The Broad band spectrum underwater detectors transmit signals in multitudes of frequencies concurrently. Broad band spectrum transmits 17 frequencies together ranging from 1.5 – 25 kHz.

These underwater detectors can be used as you move around beaches. You can as well use them in waters that are not so deep for instance waters to the waist level. Deep sea divers can use them in deeper depths to locate relics, coins and even ship wrecks. But the chances are numerous you will get precious metals, antiques, coins etc.
