One thing I want you to note is that not every metal detector has discrimination function. In the exact context of underwater metal detectors, this is a critical feature now that there is a lot of trash in the waters. From the description of a metal detector, it is clear that it detects all metals including trash like iron ore. Here, the detector transmits multiple frequencies simultaneously in the mineralized water giving you more depth. Some of the examples of the best waterproof metal detectors include, Fisher CZ21 and Garrett Infinium LS which work well over 200 ft deep while others work at much lower depths.

This detailed guide on the top 5 underwater metal detectors are not just helpful, but also give a great insight on each product. Although recovering them requires digging down deep, it is much easier and quicker to dig deep in the water than on land. Sensitivity should be at maximum but not too high if you want your metal detector remain stable producing no false signals. If you use a multi-tone ID metal detector, utilize zero discrimination and dig all but iron targets.

It also doesn’t come with waterproof headphones – you’ll need to buy these separately. Both are fully submersible to a depth of 10′ and provide excellent performance. While it’s true that the best VLF models have manual ground balance, sensitivity adjustment and other settings metal detector underwater to minimize the effects of difficult conditions, they can’t match PI machines when it comes to ignoring mineralization. VLF detectors are often a cheaper alternative to PI that are less specialized. They also provide excellent sensitivity to valuable metals and great depth.

Minelabs is a household name here some of the best saltwater metal detectors including Fisher Gold Bug. Most importantly, it offers accurate IDs, and its accuracy is not affected by the salts like in a single frequency detector. An essential feature in metal detectors is the user interface, and this is a conversation you want to follow if you are a beginner. However, there is one thing you need to be aware of; recommended working depth. This is where the electrical components are, and thus, the compartment needs to be kept away from water lest you have it toasted.
