Fisher F22

Features Galore

Fisher F22 is a powerhouse that is able to deliver on just about every front. The model's re-tune speed is ridiculously fast, its target separation is off the charts, and the detector's four search modes, including Discrimination, Sensitivity, Notch, Pinpoint will allow you to effortlessly sift through trash and dig up gold.

Incorporating 9-segment target categories and 0-99 numeric target ID enhanced with the 4-tone audio ID system, the device makes it possible to easily identify different buried targets. You'll even be able to choose your own tones.

The aforementioned discrimination system here is just as good as everything else. It will let you pass on unwanted iron, screw-caps, foil, and pull-tabs in favor of real gems hidden down below.

Using the Fe-Tone adjustable iron audio, you'll be able to set the volume of ferrous targets noticeably lower than non-ferrous targets'. It offers increased clarity for desirable targets.

All that being said, the model's biggest selling point is its detection depth. You'll be able to search for coins up to 12 inches deep and hunt larger objects 40 inches under the water.

Long story short, what we have here is arguably the best underwater metal detector on the list. The model will certainly suit amateurs but a good chunk of its features might go above their head. Which is why we will recommend this thing to experienced detectorists first and foremost, the people who'll be able to appreciate all of the complex functions that the model has to offer.

What's more, the unit's stem and coil are very much waterproof, so you'll be able to use this metal detector underwater as much and as well as the next model.

DR.ÖTEK Waterproof Pinpointer Metal Detector

One-Button Design

DR.ÖTEK Waterproof Pinpointer Metal Detector isn't necessarily the most overall impressive product on the list but the model has its moments. For one, it doesn't eat up batteries as much as these devices usually do.

Generally speaking, it will be able to last for 50 hours straight on a single 9V battery. The visual LED indicator, as well as the LED flashlight, do not consume much energy at all but are bright enough and effective at the same time.

There's no sound indicator though. The people behind the product advertise it as the model's advantage since its vibrating mechanism and the LED flashing alarm do the trick just fine without the often annoying audible noise. While they do have a point, an optional audible indicator definitely would not have ruined the product.

On the other hand, the model's fully waterproof housing with its IP68 protection class is an undeniable advantage. The model is very much submersible and you can go diving to just about any saltwater beach with it.

We can definitely get behind the products' one-button design. Just press that button and you'll be able to immediately reconfigure the detector.

All things considered, DR.ÖTEK Waterproof Pinpointer Metal Detector is as small as a toy but as effective as the next professional tool. You can use it anywhere. It will help you locate metal pipes, wires, reinforced concrete, and control boxes hidden in walls and ceilings. Metal screws, thumbtacks, and jewelry will not be able to escape it.

You might, however, have some issues deep underwater. Sure, the model's probe is waterproof but the housing isn't, so you won't be able to dive with the detector.

What Is an Underwater Metal Detector?

Your sense and/or spirit of adventure usually dims down as you grow older. It gets more difficult to find new hobbies and things that excite you the same way things used to excite you back in the days. It doesn't have to be that way though.

For example, you can have so much fun at the nearby beach. Just grab one of these underwater metal detectors and you'll be able to scour the sea for many different treasures. There's a very good chance you'll find it as thrilling as your early-day adventures.

However, you will need the right tool to make these adventures successful. The right tool should have the right coil. The waterproof part here comes without saying but the size matters here too. More often than not, larger coils have higher sensitivity specs.

Every model on the list features a waterproof probe and/or cone but not every model is fully waterproof, so keep that in mind too. Other than that, consider the operation frequency, detection modes, and sensitivity settings and you should be able to make the right choice.

Snorkel masks will come in handy too. Don't care too much for the water? Regular metal detectors will fit you better then.
