A water detector is one that helps you find treasures underwater thanks to its sensor, but if you want to know the difference between each other's natural gold read our article.

Using an underwater metal detector adds an extra layer of excitement and fun to your treasure hunt.

And in this article, we're going to analyze the types of metal detectors for underwater explorations that you should consider, how you can best limit your search and analyze their performance.

Types of water detectors and how they work

There are two types of underwater metal detectors.

Pulse induction (PI) metal detectors operate by sending several fast electronic pulses to the ground.

Electric currents are not affected by minerals in the soil or by wet sand and are very sensitive to precious metals.

This is the best metal detector for the beach as well as for diving.

In fact, you can use this type of water detector for deep searches, but you should keep in mind that PI detectors are not very discriminatory, so you'll hear pings for all metals even if they're not as valuable.

The other type of technology used for underwater metal detectors is called Very Low Frequency (VLF).

These are really sensitive to jewelry, coins, and relics, and are less likely to tell you every piece of metal you can scan.

This circuit is affected by minerals in the soil and has a sensitivity adjustment control so you can minimize those effects before you go out each time.

However, we leave you two options to choose from based on your underwater detection needs at this time; equally, they are excellent options to consider:

JW Fisher Pulse 8X

With a casing for 200 feet (61 meters) deep rating and a maximum detection range of 6 feet (2 meters), the Pulse 8X is Fisher's first-line detector. Its robust construction and high sensitivity make Pulse 8X the choice of professionals everywhere.

This commercial-grade metal detector is used by treasure hunters, commercial diving companies, law enforcement agencies, and military units worldwide.

Fisher 1280

The Aquanaut, submersible, and deep-searching, offers automatic on/off operation for salt water, fresh water or land use.

VLF discrimination, LED intensity target, and our patented quartz crystal circuit offer up to 75 hours of battery life.

For ease of use, the control box becomes a belt mount.
