Finding the right waterproof metal detector can be difficult for beginners. While an experienced user might already know what features they want and be willing to shell out well over $500 for a high-performance model, those new to the hobby with limited knowledge may not be. Unfortunately, buying a low-quality unit can often lead to becoming disillusioned with treasure hunting, since they may not discriminate between junk and valuables well enough, or worse, simply not detect anything at all. That being said, we believe we have done a good job of identifying good models for both beginners and old hands.
Beginners who aren't yet ready to make a big investment, but still want something that performs reasonably well, should look to the Bounty Hunter Land Ranger Pro or Bounty Hunter TK4 Tracker. Though these both only have a waterproof search coil and pole, they are budget-friendly and perform better than most other units in their price range. If having a waterproof coil isn't that important to you, then you may want to check out our more comprehensive list of metal detectors for beginners.
If you are a diver, whether a beginner or not, you don't just need a fully submersible unit, but one that can withstand depths of at least 25 feet, such as the Fisher CZ-21, Whites TDI BeachHunter Extreme, Minelab Excalibur II 1000, Fisher 1280X Aquanaut, and White's Surfmaster DF. Deepwater divers will want to restrict themselves to choosing between the Fisher CZ-21, Minelab Excalibur II 1000, and Fisher 1280X Aquanaut, which are all designed for use at depths well over 100 feet. It is worth mentioning that the Fisher 1280X Aquanaut is not ideal for saltwater use, since it only utilizes a single frequency, though it will work well enough for the periodic marine dive.
The Minelab Equinox 600, Garrett AT Pro, and Garrett Pro-Pointer are also fully submersible units, but not designed for use more than 10 feet deep, so they are best for waist-deep wading or perhaps very shallow snorkeling.
