Underwater Metal Detectors Buying Guide

Underwater metal detectors are used by treasure hunters, sport divers, archaeologists, the military, and law enforcement, all for different purposes.

Large underwater construction companies use them to place cables and pipelines.

The most common feature of underwater metal detectors is the ground balance, depth, detection mode, alerts, and sensitivity.

Some detectors have adjustable depth searches. The higher-end detectors will give you a distinctive alert, depending on the metal it is sensing.

They have modes for different types of searching and prospecting. These can be used in saltwater as well as freshwater.

These types of metal detectors are based on digital technology. They are equipped with several operating modes, with the normal mode as a single tone. The normal mode is typically used for finding things along the beach.

Different modes and audio signals will indicate small targets or targets deep in the water. The larger targets will give a much stronger signal.

There is a pulse on the underwater metal detectors, which helps to adjust the depth, battery life, and sensitivity.

They have circuitry made for deep searching and search coils and headphones.

Some of these detectors use advanced technology for pulse induction. This gives the user better stability in mineralized environments and detecting depth.

Looking into the more advanced underwater metal detectors, you will find electronics built into the headphones.

This will make the detector easier to maneuver and lighter in weight. They will have a heavy-duty negative buoyancy search coil.

They also have an operating search frequency that is crystal-controlled. The more advanced underwater detectors will consist of permanently encapsulated headphones with high-output transducers. The headphones have a heavy-duty polymer ear surround and excellent noise-canceling features.

They will work in the rain, on the beach, and even in storms. Additional features of these underwater metal detectors are the handgrip, armrest, silent search, and isolator.

Main Type of Underwater Metal Detector

The hobby of metal detecting underwater requires participants to develop good hearing discrimination. The frequency and intensity received by an underwater detector should be listened to carefully, and by utilizing a good metal detector, the task of discriminating is made easier and is learned quickly.

Underwater metal detectors are broken down into three categories:

  • Very Low Frequency, or VLF
  • Pulse Induction, or PI
  • Broadband Spectrum, or BBS

First, let’s go over Very Low Frequency. These send a frequency from 3 to 30 kHz into the ground to locate items.

VLF detectors work very well in locating coins and jewelry and greatly eliminate readings on unwanted objects.

VLF detectors are affected by ground minerals, so you will need to keep that in mind. However, you can adjust the sensitivity, helping to alleviate this problem.

Next, Pulse Induction. Pulse induction underwater metal detectors send electronic pulses into the ground. These pulses are very sensitive to jewelry and precious metals.

PI’s work very well if you’re a scuba diver because they work in saltwater, detect very deep in water, and are not affected much by the ground minerals in the sand. However, PI detectors can pick up many more unwanted items than VLF detectors.

Last, Broad the Band Spectrum. What BBS metal detectors do is very similar to VLF detectors in that they send out frequencies into the ground.

However, unlike VLFs that send out one, BBS sends out multiple frequencies simultaneously, ranging from 1.5 to 25kHz.

Although looking for underwater treasures in the deep and around ship wreckage may be exciting, do not forget about the areas close to the beach. Think about it: people sit on the beach and lose jewelry, coins, cell phones, watches, etc.

The tide comes in and carries this stuff out to sea. Then you come with your trusty metal detector, starting from the shallows, and work your way out. There has got to be unlimited potential for what you can find.

How To Choose The Best Underwater Metal Detector

Underwater metal detectors are specially designed to detect metal objects in bodies of water, making them a great tool for treasure hunting, diving, and beachcombing. Choosing the best underwater metal detector can be daunting, as many factors must be considered. In this article, we will discuss the key features to look for when selecting the best underwater metal detector for your needs.

1. Depth Rating

The depth rating is among the most important factors when choosing an underwater metal detector. This rating indicates how deep the detector can go without malfunctioning. Choosing a detector with a depth rating that matches your intended use is essential. For instance, if you plan to dive deeper than 10 feet, you should look for a detector with a depth rating of at least 200 feet.

2. Frequency

Frequency refers to the number of times the detector’s coil sends a signal per second. High-frequency detectors are best for detecting small objects, while low-frequency detectors are better for larger objects. Consider the size of the objects you plan to search for and choose a detector with a frequency that matches your needs.

3. Type of Coil

The type of coil on an underwater metal detector can impact its performance. Concentric coils are better at pinpointing small objects, while wide-scan coils cover larger areas. Determine what type of objects you are most interested in detecting and choose a coil that matches your needs.

4. Battery Life

Battery life is essential, especially if you plan to use the detector for extended periods. Look for a long battery life detector and consider purchasing spare batteries.

5. Sensitivity

Sensitivity refers to the detector’s ability to detect small or deeply buried objects. Choose a detector with adjustable sensitivity settings to suit your specific needs.

6. Discrimination

Discrimination is the ability of the detector to distinguish between different types of metal. Choose a detector with adjustable discrimination settings so you can filter out unwanted metals and focus on finding the ones you’re interested in.

7. Durability

Underwater metal detectors need to be durable enough to withstand the harsh environment of the water. Look for detectors made from high-quality materials and with a waterproof design.

8. Price

Underwater metal detectors can vary greatly in price. Set a budget and look for a detector that fits within it while meeting your needs.

In conclusion, choosing the best underwater metal detector requires considering various factors such as depth rating, frequency, coil type, battery life, sensitivity, discrimination, durability, and price. Considering these factors, you can find the right detector for your needs and budget.


Underwater Metal Detecting Tips

Possessing it is one thing. Using it’s another.

Knowing where and how to use an underwater metal detector will assist in deciding on the best sort when it comes to purchasing.

The fundamental tricks in using submerged metal detectors are:

Waterproof cans

In listening to any metal detection from a distance determined by how good the sensor is, having a waterproof headset helps.

The headphones block out any outside noises that will interfere with hearing any noise made by the metal detector.

Tank and snorkel

This will be convenient. A snorkel and a tank will assist in breathing, depending on how deep the diver would need to go. One mightn’t require a tank if they are merely going to a knee-high degree.

Watertight watch

Deep-sea needs, in many cases, this when going deep into the ocean to assist them in breathing underwater, and Deep-sea divers must take air tanks.

At some stage, the tank must run out of the atmosphere, and the diver must return to the water’s surface to exchange the tank.

A watertight watch is needed to time underwater in compliance with the air tank to ensure that air doesn’t run out on you without your knowledge.

Take Tote

A carry bag for the metal detector becomes helpful, particularly if you’ll need it along the seashore or if you’re employing your sensor in knee-high water.

It keeps the sensor protected and prevents the entry of sand particles inside the sensor.

Monitoring device

For divers, having a tracking device installed in the metal detector is needed. This will ensure that the remainder of the deep-sea divers stay connected with you and can easily locate you once you’re not in sight.

In some cases, where the diver gets lost in the deep sea, it will assist the investigation team by using this tracking apparatus to locate them.
