How metal detectors work

Every metal detector transmits an electromagnetic field from its search coil into the ground. If there is any metal object within this field, it will become energies and then retransmits its own electromagnetic field.

The search coil on the metal detector will receive the field and inform the user that there is a metal hidden underground which is producing a response. It might make a clicking or beeping sound. There are some detectors that can identify wanted and unwanted targets.

Challenges of Salt Water

The major problem of metal detecting on the beach is the rock and saltwater. The content of the water increases the effects of ground materials. This confuses land metal detectors, and as a result, they sometimes pick on wrong signals. It poses a huge problem to the detectors with preset ground balance.

Because of this, you will need a detector that is capability of ignoring the effects of saltwater. Whether you want to hunt on wet sand or in the ocean, you will need a detector that is waterproof to avoid frustration and difficulties.

7 Best underwater metal detector

There are various differences between a metal detector that is weatherproof or waterproof. Any detector that can be fully submerged into water is completely waterproof. You can use it underwater without causing damage to it. However, the depth it can go depends solely on the capacity of the detector. Even though your detector has a submersible coil, it does not mean it can be submerged inside water. Most detectors have a control box that cannot get wet.

So, a metal detector with a waterproof coil might necessarily not be able to function underwater.
