One of the most exciting moments for treasure hunters is to lift a relic or a treasure they have found underwater. This can be a shiny golden necklace, crown, cup, shield, sword and other highly valuable items. If you’ve spend quite a while metal hunting on a dry land, there would come a time, you would want to move in the water, or for more challenge go underwater diving. The reason professional metal detectors go underwater is because of the vastness of the ocean, which is usually rich in underwater treasures from shipwrecks and plane crashes.

There is actually some truth to some claims of divers that there are more jewels, coins, and treasures down there on the sea floor, more than you can find in circulation on land. If you’ve pondered and decided to use metal detectors for some underwater search, you would need to learn more about waterproof metal detectors, how they work, and your options on what type of device to get.

Two types of technologies:

Some people prefer to do their metal search in water lines, wet sands, and shallow waters; while others choose hunt deep underwater. There are two different technologies used for these areas.

Very Low Frequency (VLF)– These metal detectors usually operate in frequencies with a range from 3 to 30 kHz. The VLF devices are more sensitive to items such as relics, coins, and jewelry. It can discriminate these valuable objects from junk metals that appear in the signals. Metal detectors with low frequencies can easily be distracted by other types of minerals in the soil; which makes it easily confused with the readings. However, you can adjust this sensitivity,as well as adjust the ground balance, so the signals of the minerals are minimized. There are brands of metal detectors with VLF that can be used to search metals in water lines, wet soil, and shallow waters.

Pulse Induction(PI) – These metal detectors, on the other hand, can transmit pulse signals fast, which allows the device to disregard ground with too many minerals. PI devices are commonly used by professionals looking for precious metals. It is the common type used if you like to search for valuable items deep diving, salt water and beaches. Pulse induction detectors can pick up signals from great depth, and can get through over mineralized areas. However, you would need to dig more since most models have limited discrimination functions.

Where will you use the waterproof metal detector?

Even if this device can shield away water and moisture, not all types can be fully submerged in the water. Some of the common places where these detectors can be used are the following: beach coast, water lines, wading the water from your knees to your waist and deep water diving. For divers, some of the common places are shipwrecks and historic sites below water.

As you take a time to choose the best water metal hunting device, you may grope to find what type of equipment you should get. If you would like to search in the sea ocean, you would need the Pulse Induction type of metal detector, since this is specialized in saltwater conditions. However, if you plan to get a VLF type for all around land search, but sometime in the future plan to use it on the beach, make sure to find the VLF product with a saltwater setting. VLF products since it is low in frequency experiences a lot of problems in salt and mineral environments.

What about underwater metal detectors? 

If you prefer to do your search in your diving expeditions, you should first consider the depth of your diving spot. You should check the detector’s depth rating before getting a given product. Keep in mind, that the depth rating is not necessarily the ground depth on how the device can penetrate; but the depth of the water where you will use the equipment. If you will be snorkeling or diving, you want the product model to include a short dive pole. This diving pole can actually aid your dive in a variety of ways.

What accessories would you need?

The detector is your main tool in underwater treasure hunting, but there are also accessories that help an underwater treasure hunter.  Some of the basic accessories you should get are the following:

Metal Detecting Accessories

Headphones – This will allow you to audibly hear the deep targets, old targets, as well as block the external sounds and noise. Most of the standard underwater detectors include a set of water-resistant headphones, but you should get one in case it is not included in the purchase,

Carry Bag – If you want the best way to protect your brand new treasure detector, you would want a carry bag to help you transport the device and other accessories. W

Trowel – This is an accessory you can use while you hunt along coastlines and beach area.

Metal Detector Sand Scoops – The scoop will help you speed up the recovery when you go searching in the sand.
