10 Best Waterproof Metal Detectors 2025 in the United States

The Minelab X-Terra PRO is designed to meet the needs of treasure hunters looking for a versatile and waterproof metal detector. With a waterproof rating allowing for submersion up to 16 feet, this model is ideal for beachcombing or treasure hunting in rivers and lakes. One of its standout features is the Pro-Switch technology, enabling users to switch frequencies for better depth detection, which can be very beneficial when searching for various types of metals.

The flexibility of three detect modes—Park, Field, and Beach—makes it suitable for different environments, whether you're in a high-trash area or looking for fine artifacts. The built-in flashlight and backlit keypad enhance usability during nighttime searching, and the option for audio control, which allows you to distinguish between different targets, adds another layer of sophistication.

Weighing in at just 2.9 lbs, this metal detector is lightweight and easy to handle, making it suitable for long search sessions without causing fatigue. Its compact design means it can be easily transported in a backpack, perfect for adventurers on the move. The Minelab X-Terra PRO is a great choice for casual and serious treasure hunters alike, particularly those who plan to search in various environments, including underwater. With solid performance and ease of use, it offers good value.

This ULHUND metal detector is a solid choice for beginners and casual treasure hunters, especially those interested in beach or shallow water searching. Its IP68 waterproof rating means the stem and coil can be submerged safely, allowing you to hunt in water or wet sand, but the control box itself isn’t waterproof, so avoid full immersion of that part. The detector uses a 10-inch coil and an upgraded DSP chip, improving detection accuracy by about 26% compared to basic models, with a depth reach up to 12 inches — good for finding various buried metals.

It offers four searching modes and can identify nine types of metals, which helps in distinguishing valuable finds from junk. The discrimination and pinpoint features let you better target specific metals, making your hunt more productive and less frustrating. Weighing just 2.4 pounds and featuring an adjustable stem and ergonomic armrest, it’s comfortable to use for extended periods, which is important if you’re walking on the beach or yard. Battery life is strong at about 20 hours using two 9V batteries, so you can enjoy long sessions without frequent replacements. The large backlit LCD screen is beginner-friendly, providing clear information even in low light.

The package also includes helpful extras like a carry bag, foldable shovel, and earphones, adding good value. However, the total weight listed is around 5.5 pounds, which might include accessories, potentially making it a bit heavier to carry than the detector alone. While it’s great for beginners, it may lack some advanced features sought by professional users. This detector balances ease of use, decent accuracy, and waterproof capability, making it a practical pick for those starting out or enjoying metal detecting as a hobby near water.

The MINELAB MANTICORE Metal Detector Professional Bundle is designed to appeal to serious treasure hunters looking for a reliable and powerful waterproof option. One of its standout features is its advanced technology, which offers 50% more power than many competing models. This could significantly enhance your ability to detect targets quickly and efficiently, even in challenging environments. The simultaneous multi-frequency capability is particularly beneficial for diverse soil conditions and types of metal detection.

The PRO-FIND 40 pinpointer included in the bundle is also a strong asset. Its waterproof design and Detector Interference Free technology help in accurately locating treasures without the frustration of signal interference, which can be common in metal detecting.

When it comes to comfort and usability, the MANTICORE boasts an ergonomic design that makes it manageable to use over extended periods, although its weight could be a concern for some users who may prefer a lighter device. The 11” double D coil is well-suited for both depth and sensitivity, making it effective in various detection scenarios. Battery life is adequate but could be a limitation for those planning extended outings, requiring the user to carry extra batteries. Additionally, while the included carry bag is practical and protective, it might not be large enough for additional accessories that serious hobbyists often wish to bring along.
