When it comes to metal detectors, there are many detectors that are not waterproof, but many new detectors have hit the market in the last couple of years that are. Some are made to withstand water up to 10 feet deep, while some can even go further down in the water than that. The detectors that can go deeper than 10 feet are meant more for scuba diving, while the others were made for detecting in rivers and lakes. All of these detectors listed below are protected from rain so don’t let the weather stop you. The Minelab Vanquish 540 & Garrett Ace Apex has waterproof coils and I wanted to show them so you can see a detector for a budget price and still search in shallow waters.

Some detectors are made to detect in freshwater while others are meant to work in saltwater, but we’ll get more into that on another blog at another time. This blog is about waterproof metal detectors. To get more information on detectors for wet sand, black sand, freshwater & saltwater, read our description details on our website. To help you narrow down the detector that matches your hobby and budget, I will include the normal retail price along with short descriptions with links so you can learn more about each one.


Best Waterproof & Underwater Metal Detecting



Aside from being waterproof, underwater metal detectors work differently to find metal through water, wet sand, and different textured ground. There are two types of metal detectors that work underwater: pulse induction (PI) metal detectors, and exceptionally low frequency (VLF) metal detectors. Pulse induction metal detectors work underwater by sending electronic pulses that are not affected by water and wet minerals. They send rapid electronic pulses that are sensitive to precious metals, so they can detect through the wet or mineralized ground. PI metal detectors are the best choice for use on beaches or for deeper treasure hunting.

Very low-frequency metal detectors work through water and wet surfaces, but the circuits are more affected by mineralized ground. You can adjust sensitivity settings as you search to ensure VLF metal detectors work through mineralized surfaces. They are extremely sensitive to coins and jewelry but will not detect every small piece of lesser metal.

If you have any questions, please feel free to reach out to us with questions. Our staff of professionals come with many years of experience and are eager to help outfit everyone with a detector. While you are shopping around, don’t forget about digging tools, accessories, and extra search coils. You can visit our Youtube Channel for videos on metal detectors, coils, and accessories.
