Waterproof metal detectors make locating treasure on the beach and in the ocean a reality.


If you want to take your hobby of metal detecting and turn it into a passion, then adding waterproof metal detectors to your kit and equipment may be the next step. A waterproof metal detector takes the search for coins, jewelry and relics underwater and into wet areas. Adding a waterproof metal detector to your array of equipment can completely change your searches and increase the number of items you find during a hunt. After all, when we enter the water with jewelry on, the skin shrinks and valuables fall off. It is a little known fact that there is more buried jewelry and coins lost than there is in circulation!

Waterproof metal detectors do not come cheap but do offer more advanced detecting opportunities and rewards. So, if you want to improve your ability to find great items hidden to the naked eye, then upgrading to a waterproof metal detector is a great move.

Waterproof metal detectors: Beach searches

You may wonder why detectorists are always searching the beach. It is a common sight, seeing men and women walking across the sands with a metal detector in hand, headphones on and eyes glued to the sands.

The reason you often see detectorists searching the beach is due to the amount of coins and jewelry that is lost in the sand. In addition, the oceans are the best movers of debris around the globe. You can find valuables that have been washed ashore but hidden by the sands.

The beach is the ideal place to use a metal detector and that is why detectorists can be seen on beaches in the early mornings around the globe. What items can you find on the beach? Coins are a popular item as people drop them while shifting them into their pockets. Once a coin hits the sand, it can be difficult to recover it if you don’t have the proper tools.

Jewelry is a common find on beaches due to the weather and water. Fingers can shrink due to the cold weather on the beach or be washed off by waves. Rings can then be covered up by sands while necklaces and earrings can also fall off at the beach. All three items are major finds and detectorists can cash them in for financial gain. In many cases, it is not uncommon for a detectorist to be able to locate the original owner through an inscription on the item.

A normal metal detector may not be rugged enough for the beach. In addition, you need a waterproof metal detector which will allow you to go into the water to continue your searches. Depending on the depth capabilities of your waterproof metal detector, you can search further down in the water. You may be able to find even more hidden treasures and relics under the water’s surface while snorkeling or diving.
