In the case of salt water, the exterior may not be able to withstand corrosion from salt while the interior of the machine may be too sensitive to it. They may be better suited to finding jewelry and relics and they’re better in fresh water than PI detectors. Pulse induction models tend to be more expensive, but there are some benefits to choosing a VLF model, too.

A waterproof watch makes it easier for divers to keep track of the amount of time they have spent inside the water with an air tank. ​ Ease of Use:  Beginners may not experience much trouble in operating a standard metal detector. ​ Quality :  Underwater metal detectors are manufactured while maintaining high quality standards. Weight:  An underwater metal detectors is typically lighter as compared to regular detectors. Waterproof:  Regular metal detectors are not waterproof and can suffer from extensive water damage that can void your warranty.

These devices are commonly amphibious being partly able to function in water and on land. If you’re looking for an underwater VLF detector that doesn’t cost a fortune, the 1280-X is one to consider. It’s more susceptible to interference from wet sand, but has manual ground balance and discrimination to counteract trash and mineralization.

The pulse induction type of detectors won’t be affected by a high mineral content which can come from the salt in the water as they will be able to see a much clearer view of the ground below them. The other big consideration is due to weight, as there are a lot of waterproof metal detectors generally weigh more than their land counterparts. There are of course waterproof metal detectors which are handheld which will be more difficult to use on land. There are two levels to this when it comes to products that can go underwater with the traditional looking metal detectors and those are the coil and the control box.

As you saw in our reviews above, some models can work in very deep water, up to 250 feet below the surface. However, they also don’t do as good a job of filtering out junk, so you may spend more time in unnecessary digging than you would with a VLF detector. Of all the waterproof products on the market, this one is probably the best on land.

It has a 1/8 inch headphone jack for private hunting and for use in noisy areas such as parks. It water metal detecting is still ideal for children though as they will not have enough time to look into such detail.

From finding coins at your local park, to prospecting for gold in Africa, or even clearing landmines in South East Asia, Minelab has a metal detector especially suited for the task at hand. You could still use a Very Low-Frequency Metal Detector but ensure that you lock it at the salt water mode. While buying your underwater  metal detector, it is very important to know if the machine will work for you. The materials used to manufacture underwater metal detectors should be waterproof and durable.

This model also comes with a headphone jack for underwater use. We also really like that this product has both All Metal Deepseeking Mode Audio Threshold and Adjustable Audio Tone ID Discrimination.

PI metal detectors are the best for salt water environments and scuba diving. Our review of the best underwater metal detectors will take you through a range of VLF and PI metal detectors to suit your needs and budget. This gold detector is a versatile device that can be used in various places such as parks, beaches and fields of ancient wars .
