The 12 Best Waterproof Metal Detectors

Many metal detectors are not waterproof, but many new products have entered the market in the last few years that are. I know of several that are designed to resist water up to approximately 10 feet deep, while others are capable of going much deeper. So this is why is essential to know which are the best Waterproof Metal Detectors for you.

The metal detectors that can go deeper than 10 feet were primarily designed for scuba diving, while others were designed for lake and river detection.

The following best metal detectors are both waterproof and rainproof, which means the weather does not affect you in any way.

Some metal detectors are designed to operate in freshwater, while others are developed to function in saltwater. However, this specific blog is about metal detectors that are waterproof.


What Waterproof Metal Detector Types Are Available?

The two metal detector types for underwater activity are:

  •       VLF (very-low-frequency) detectors
  •       PI (pulse induction) detectors


VLF Metal Detectors PI Metal Detectors
Water and damp surfaces are not a problem for VLF metal detectors; however, mineralized ground has a larger impact on the electronics. To make sure that very low frequency metal detectors operate across mineralized surfaces, one may change the sensitivity settings. Jewelry and coins are highly sensitive, but they cannot detect all small pieces of lesser metals.


PI underwater metal detectors operate by transmitting electrical pulses that are unaffected by wet minerals or water. These send out frequent electronic pulses that are responsive to precious metals, allowing them to discover precious metals even when the ground is mineralized or wet. Pulse induction detectors are the best option when searching for deep treasure or on beaches.



Do you have any questions? I am more than happy to assist you. When choosing the best value waterproof metal detector, do not forget about digging equipment, gadgets, and additional quest coils.

How to Use an Underwater Metal Detector

I’ve found that detecting metal in water requires specific techniques.

You can use a detector by doing the following:

  1.     It is essential to mark any targets you discover as quickly as possible. The most straightforward method is to position one of your feet behind the mark and keep it there until you dig up the item.
  2.     Locate the scoop in front of your foot that marks the area and try to get a deeper scoop of sand until you have marked the region of interest.
  3.     Test the space with the detector once again without loading or filtering the sand in the pick.
  4.     If the item is still there, empty the scoop and refill it with sand.
