10 Best Saltwater Metal Detector 2025 in the United States

The MINELAB X-Terra PRO Waterproof Treasure Metal Detector is a solid choice for both beginners and more experienced users looking for a versatile and reliable metal detector. One of its standout features is the PRO-SWITCH technology, which allows you to switch frequencies to detect various types of metals deeply and accurately in different environments. This makes it highly adaptable, whether you're searching in a park, field, or beach. Its waterproof capabilities allow submersion up to 16 feet, making it ideal for finding treasures in both wet and dry conditions, like at the beach or in shallow water bodies.

With three detect modes—Park, Field, and Beach—you can easily tailor the device to your specific searching conditions and targets, whether it's coins, jewelry, or artifacts. Audio control features include options for distinguishing between trash and treasure and gauging the size and depth of a target, compatible with both wireless and wired headphones for convenience. Weighing only 2.9 lbs, the X-Terra PRO is lightweight and compact, facilitating prolonged use without causing fatigue. It packs down to 25 inches, fitting easily into most backpacks, which makes it highly portable.

While the detector is lightweight, it requires a lithium polymer battery, which is included, but it may require frequent recharging depending on the length of usage. Another minor drawback could be its reliance on an LCD display, which might be challenging to read under direct sunlight despite the backlit feature. The build quality using plastic is practical but might not feel as premium as other materials. Despite these minor limitations, the X-Terra PRO offers a strong blend of performance, ease of use, and versatility, making it a top choice for treasure hunters of all skill levels.

The MINELAB Equinox 900 is a well-rounded metal detector particularly suited for saltwater environments. Its standout feature is the simultaneous multi-frequency technology, allowing users to select from six frequencies or utilize five frequencies at once. This capability enhances its effectiveness in different soil and metal conditions, making it versatile for both land and underwater treasure hunting.

Waterproofing is another major strength, with an impressive capability to be submerged up to 16 feet. This makes it an excellent choice for beachcombers or those looking to explore rivers and lakes. The four detection modes (Park, Field, Beach, and Gold) cater to various searching needs, helping users focus on specific types of targets.

The detector is also designed with user comfort in mind. Weighing only 2.8 lbs, it’s lightweight and portable, ideal for long treasure hunts without causing fatigue. The collapsible design makes it easy to store and transport. In terms of usability, the accurate target identification and audio control features help differentiate valuable finds from junk, which is crucial, especially in areas with mixed signals like sandy beaches. The MINELAB Equinox 900 is a strong choice for those serious about metal detecting in saltwater, combining advanced technology with user-friendly design.

The Garrett AT Pro Metal Detector is a solid choice for those who need a versatile and reliable metal detector for saltwater environments. One of its standout features is its ability to ground balance in saltwater, making it ideal for beach hunts. The device is waterproof up to 10 feet, ensuring it can handle shallow dives and wet conditions without issues. The proportional audio and Tone Roll Audio are beneficial for distinguishing between different types of metals, which is a handy feature for more experienced users.

Its Iron Audio capability further enhances discrimination by allowing users to hear discriminated iron and adjust the mid-tone signal range, which can save time by avoiding unwanted targets. However, the product has some drawbacks. The Garrett AT Pro requires batteries, which some may find inconvenient, and the waterproof headphones needed for full submersion are sold separately. At a weight of approximately 1.37 kilograms, it is relatively lightweight, but prolonged use may still lead to some fatigue.

The included MS-2 headphones are an added bonus for land use, but investing in additional waterproof headphones is necessary for complete underwater exploration. With a solid customer rating of 4.6 out of 5 stars and being well-regarded within its category, the Garrett AT Pro is a reliable metal detector for hobbyists and more advanced users alike.
