They aim to penetrate down through the surface to check if there is any metal down below. A: Yes, absolutely, as their primary function will still work whether that is over dirt or if it’s over sand.

This is also another underwater metal detector that will surely pique your interest. Additional, this underwater metal detector is capable of boosting audio input making it easy to find faint targets. This device features waterproof speakers hence making it the ideal scuba diving metal detector.

This waterproof metal detector works on a 15kHz frequency to find the small stuff with the 0-99 target scale ID to indicate what’s beneath. This is the best underwater metal detector that also has a discrimination mode with seven-settings to filter out your metal choices, although many users tend to pick auto-tune which turns it into an all metal mode with deeper penetration but no discrimination. In our opinion, the Fisher CZ21-8 is the best underwater metal detector on the market. Once you know what you want then you can head out to the water and start hunting for your treasure with your new metal detector. This is a traditional looking metal detector from Tesoro which is able to go under the water with its 10.5 inch coil which will be able to do a great job at detecting any hidden treasures that might be lurking beneath the waves.

Recently a new technological feature was added to metal detecting, so we do not only have underwater metal detector machines, but also waterproof headphones to go with them. The Sand Shark‘s depth capacity is a pretty impressive 200 feet, which makes it the best underwater metal detector. This underwater metal detector is a pulse induction machine, which means you do not have to spend long hours with adjusting all the features and setting up all the ground balancing, but you can simply go and start searching right away. You should choose an underwater metal detector with a larger search coil because the bigger the coil, the higher the sensitivity. I’d really recommend getting yourself the best underwater metal detector you can afford if you are spending lots of time in or near the water.

It costs around the same amount as the Sea Hunter MkII and has similar features, including a depth rating of 200 feet and pulse induction technology. Garrett has also designed the Sea Hunter to be suitable for both beach hunting and diving. Aside from the discrimination function, the Sea Hunter Mark II comes with several search modes, including Non Motion All Metal and Standard PI Discrimination. With that in mind, here are three of the best diving metal detectors that can be used at least 200 feet below the surface.

This is a very popular and highly recommended underwater metal detector. If you are looking for the best underwater metal detector, you are at the right place. I hope this article has helped you choose the best underwater metal detector for your budget, needs and requirements. Even so, if you’re looking for a single metal detector for both land and water detecting, the AT Pro is one of the best on the market.

On the plus side, VLF detectors can discriminate junk targets, so you’ll waste less time. While it’s true that the best VLF models have manual ground balance, sensitivity adjustment and other settings to minimize the effects of difficult conditions, they can’t underwater metal detecting match PI machines when it comes to ignoring mineralization. This means they are less suitable for saltwater hunting, but are often great for both land and freshwater locations. In this case, a fully submersible detector with a high depth rating is essential.

It can do accurate target, item pinpointing and adjust detecting mode. Extra Features at the Push of a Button : Audio Boost, ID Normalization, Target ID Depth Level. However, they are not as sensitive as VLF, and there is a loss of depth. X-Terra 705 from the Australian manufacturer Minelab is the favorite device of most experienced treasure hunters. If you want to search at any time of the year, then you certainly need a wetsuit.

It’s more susceptible to interference from wet sand, but has manual ground balance and discrimination to counteract trash and mineralization. The pulse induction technology provides plenty of depth, plus the various adjustment settings allow you to customize performance to the environment. There is a dial for depth, for example, which adjusts the pulse width. Firstly, the Sand Shark has features and settings not found on all pulse induction models.

Weights of underwater metal detectors vary greatly, ranging from 1-6 pounds respectively. Underwater metal detectors will display a needle on a gauge that can detect any level of metallic content once the metal is in reach. The heavier or closer the metal is, the higher the pitch sound you’ll hear from the metal detector. A regular metal detector will pick up on the presence of nearby metals by sounding off a high pitch. That is why these underwater metal detectors are the perfect choice to bring with you for a dive.

The coil field generates pulsed eddy currents in the object, which are detected by analyzing the attenuation of the pulse induced in the receiver coil. There are two known types of metal detectors operating according to a “transmit-receive” (TR) scheme, classified by the type of magnetic field generated by the transmitting coil.

These are great for hunting lakes or on beaches but are not suitable for diving. Before you can choose an underwater detector, you need to be clear about where you’re going to use it. Nothing beats the excitement of pulling a rare relic or gold nugget from a hunting ground most hobbyists don’t even have the equipment to access. Most detectorists start on the beach or lakeside and end up drawn to the wet sand, and then the water itself. If you enjoy metal detecting it’s more than likely you’ll end up in the surf, if not deeper.
