The Science Of Underwater Metal Detection

Understanding How Underwater Metal Detectors Work

Underwater metal detectors work on the principle of electromagnetic induction. The device consists of a search coil, which acts as an antenna to transmit electromagnetic pulses through the water. When the pulse comes in contact with a metal object, it induces an electrical current in the object, which in turn creates a magnetic field.

The detector’s receiver coil detects the magnetic field and produces an audible signal to notify the user.

How To Interpret Signals From Underwater Metal Detectors

Interpreting signals from an underwater metal detector can be challenging. Here are some tips to help you understand the signal better:

  • Familiarize yourself with the different types of signal responses, such as audio, visual or vibration.
  • Check the detector’s manual to see how signals are displayed on the device.
  • Practice identifying different types of metal by burying them underwater and testing the detector’s reaction.
  • Be aware that other factors, such as soil type or nearby objects can affect signal responses.

How Different Settings Impact Detection

Settings on an underwater metal detector can be overwhelming, but understanding how they impact detection can help improve your success rate. Here are some important settings to consider:

  • Sensitivity affects the detector’s ability to detect small or deep targets. Higher sensitivity is ideal for shallow water, while lower sensitivity is better for deeper water.
  • Ground balance compensates for mineralization in the water, which can interfere with detection. Automatic ground balance is the easiest setting for most users.
  • Discrimination helps the detector distinguish between different types of metal. Adjusting this setting can help filter out unwanted signals and improve detection accuracy.

With a better understanding of the science of underwater metal detection and key settings to consider, you can get the most out of your underwater treasure hunting experience. Happy exploring!

Buyer’s Guide

Before going to purchase the best underwater metal detector, it is necessary to go through every aspect and feature of the product. Without ensuring that you are purchasing the right product according to your needs, it is useless to buy it. So, here in this buying guide section, we are highlighting some factors that you should consider before spending money on a particular underwater metal detector.

Type of Detection

The first thing that you must look at is the type of detection your underwater metal detector features. These metal detectors feature two types of deduction. One is the VLF detection that is very low-frequency detection. And the other one is the Pulse Induction detection.

VLF detectors are highly sensitive to minerals. They are designed to use in freshwater where the minerals are in low quantity. They mainly focus on those metallic and precious objects which you want to find under the ground and ignore the other things.

But if we talk about the Pulse Induction detection system, then it is not sensitive to minerals. Therefore, you can use this detection system in the ground. Also, they work in any type of soil and the saltwater. But they do catch unwanted junk which is a negative side of the PI model.

Also, if we talk about the difference in price, then PI models are more expensive as compared to the VLF detection systems.

Operating Depth

How far your metal detector can go inside the water is important to know. Some metal detectors can go as deep as 250 to 300 feet and work perfectly fine. Whereas some metal detectors can only detect metals as far as 10 to 15 feet. Moreover, there are also other metal detectors that come with waterproof coil and stem, whereas some other machines only feature waterproof coils.

So, it depends on your needs and the work you do to either select a detector that offers good operating depth or to select one that features only waterproof searching coil.

If you don’t know the art of swimming or haven’t gone deep underwater, then the metal detectors that can go more than 200 feet below the surface are not for you. But if you mostly do scuba diving, then you must go for that. However, it is recommended to select a product with greater depth because you never know when you will be going to hunt for treasure deep down the water.

Weight and Buoyancy

Another important factor that you must consider is the weight and buoyancy. As you are going to dive into the water with the metal detector so it must have neutral buoyancy so that it fails to sink quickly. Also, the metal detector must not be so light to move upwards frequently.

So, here, balance is the key. Therefore, it is necessary to check the weight of the metal detector before buying to ensure that it will not sink too quickly or try to float constantly to the top.


Accuracy is the key for metal detectors. If you have a metal detector that is not accurate, then you won’t be able to find the treasure on time. Each model differs from the other one in terms of accuracy. So, before purchasing your ideal metal detector, it is necessary to read the product description. Also, it is essential to read the reviews of the users to ensure that you are buying the right product.

If you are not going to find anything deep then you may not need a metal detector having long-range and accuracy. But if you always go deep inside the water, then accuracy and range count much because as you go deep, it becomes hard to find the hidden objects.


Your metal detector should be versatile. Some of the metal detectors only work in freshwater, whereas there are many detecting machines that work in both salt and freshwater. These types of detectors feature pulse induction technology that allows them to work both in fresh and saltwater. Also, if you want to look for metal objects on land, then these metal detectors will also help you out.

Other than this, if you want to use an underwater metal detector on land, then you have to focus on the weight of the machine as you will surely find it heavy to handle the machine on land.

Locking System

A good locking system is also quite essential for a metal detector. If you are buying a detector that is fully submersible, then it must have a strong locking system to keep the entire unit together even when the strong waves meet the stem.


As you can use the underwater metal detector on land so it must be weather-resistant if you are willing to use it on land to find out the metal objects.

Battery Backup Feature

Battery backup feature is also quite essential. The reason for this is that it will not allow the detector to shut down when the original battery loses its power. The unused extra battery will get activated when the used one becomes zero.

Additional Features/Accessories

If we talk about the additional features/accessories, then waterproof headphones are an excellent addition. Also, 2-tone audio is an improvement and must-have in your selected metal detector. Other than this, some metal detectors come with extra detecting features. When they detect any object, they vibrate as well as the bright light flashes to make you aware that you are quite near to your treasure.


Price is another thing that you must look at. Basic and simple underwater metal detectors are low in price, whereas advanced machines are expensive. Also, the type of detection determines the price of the metal detector. If there is VLF detection, then the price will be low, but if there is a pulse induction, then the price will be higher.

Safety And Tips For Safe Underwater Metal Detecting

Underwater metal detecting poses some risks, but risks can be mitigated by observing basic safety measures. Here are some tips to assist you in staying safe:

  • Always dive with a partner. Never dive alone.
  • Understand the risks before diving into the water, such as water temperature, visibility, currents, and aquatic life.
