How to Use an Underwater Metal Detector

Whether you are SCUBA treasure hunting, shallow water detecting, or wading along the shore, you will need to know how to use your metal detector. Before you get anywhere near the water, you must test the detector with targets on land. This will help you get a feel for what settings you will need to use. Since underwater detectors have a depth rating, they are fully submersible and waterproof up to that specified depth, so you do not have to worry about them getting ruined. Make sure you have the right gear, such as a sand scoop, sifter, trowel, pinpointer, and headphones. These will make you more successful in finding your targets efficiently. Waterproof headphones are a must, simply so you can hear the metal detector underwater. A key to underwater prospecting success is to swing your search coil slowly in areas that you believe could be a shipwreck, a lost jewelry-rich environment or wherever else. If you follow these tips, you should be able to find some awesome finds!

What Is the Best Underwater Metal Detector?

Pinpointing which waterproof metal detector is the best is a hard task. It truly depends on the conditions the detectorist will be facing. In many cases, a pulse induction detector is a better purchase, as wet sand is very high in mineralization. VLF, or very low frequency, metal detectors have a tougher time detecting metal objects in wet sand. While adjusting the ground balance can help, it can still be a problem. If you will be diving deep or hunting in wet sand constantly, pulse induction is probably the route to go. If you will be in more shallow water and won’t be hunting in wet sand all the time, VLF is a great choice. Either way you go, you will have a great time finding precious metals underwater!

Here at Kellyco, we provide a wide variety of excellent pulse induction machines as well as very low frequency machines. Some great pulse induction metal detectors are the Garrett ATX Extreme and the Garrett Sea Hunter Mark II, any of the JW Fishers metal detectors, and the Nokta Makro. Some incredible very low frequency waterproof metal detectors are the Garrett AT Pro, the Fisher CZ21, and the Fisher 1280-X.

How to Use a Metal Detector on the Beach

Treasure hunting on the beach is a favorite of many, as beach hunting is one of the best ways to score some jewelry composed of precious metals. To have the best shot at success, hunt places like shady areas, areas where there is a bunch of activity, and the “towel line.” Simply follow a path and grid your way across an area of the beach. Anytime you get a good signal, use your sand scoop and trowel to find your treasure. It really is that simple!

What Is the Best Metal Detector for the Beach?

Picking out a waterproof metal detector for the beach is much the same as it is for picking out an underwater machine. You have to decide between pulse induction or VLF. If you buy VLF that has ground balance features, you should be okay even in most wet sand situations. Some great very low frequency beach machines are the Minelab CTX 3030, the Garrett AT Max, the Fisher F75. Any of the pulse induction machines previously mentioned work great on the beach as well!
