Underwater Metal detector

Underwater & Beach Metal detector

Make use of a metal detector underwater, and when you scuba dive has become more accessible and cheaper in recent years. There are several models at affordable prices. 

Submersible vs Waterproof detector

There are conventional metal detectors that are waterproof and specially designed detectors for underwater and scuba diving. Some are cheaper detectors that suit hobby detectorists. And some are more expensive and are intended for professionals. The price, of course, varies accordingly. 

If you are hunting waist-deep or higher, you must have a submersible detector. A submersible detector you can use underwater – search coil, control box, and all.  

Best waterproof metal detector?

Waterproof usually transfer to a waterproof search coil and shaft. These detectors are excellent to use in shallow water and depths that don’t endanger electrical components within the control box. Most metal detectors provide some protection for shallow water hunting since the search coil and stem are waterproof, but the connections and the control box are not waterproof. 

You can check your manual on how dept in the water you can use your detector. The typical thing is that you can lower the entire search coil and a bit of the stem that holds the coil. That gives you a search dept in the water of about 30-50 cm. The sensitive part is the electronics box. How sensitive the box is, differs slightly between models, but it is necessary to be careful so that no water enters the electronics.

Rain and dust cover

Some detectors are built with protection to withstand rain and dust. Otherwise, if you are detecting in the rain, it is recommended that you use a protection intended for that particular detector. This, of course, applies if you have a regular detector, not one intended for underwater use.

Metal detector for scuba diving

When it comes to metal detectors intended for use in water, there are two types. On the one hand, detectors designed for scuba diving. And although the technology is usually the same under the hood, it may not be the most practical to use on land. 

For beach and underwater use

Then there is another group that is a combination of underwater and land detector. If you go to beaches a lot, these are the ultimate machines. You never have to be afraid that the detector will be damaged but can focus on finding nice artefacts. They work fine both on land and in water and are probably the best option for ordinary all-around detectorists if you use the detector a lot in and around the water. 

Underwater metal detecting equipment!

When deciding which detector is suitable for you, keep in mind your search area. The underwater metal detectors divide into Very Low-Frequency Metal Detectors (VLF) and pulse Induction Metal Detectors (PI).

The PI detectors are not affected by mineralized water and have enhanced search depth, so pulse Induction Metal Detectors are best suited for saltwater search areas. However, PI metal detectors are typically unable to distinguish between garbage and treasure. You need to dig up an increased number of targets to recover the maximum number of gems. 

The VLF underwater metal detectors allow you to differentiate between valuable and non-valuable finds, saving you a lot of time. It is vital to keep in mind that VLFs are affected by salt and other minerals. If you decided to go for a VLF Metal Detector, make sure it has sensitivity and ground balance settings to navigate the mineralization.
