10 Best Underwater Metal Detector 2025 in the United States

The Gbnryg Metal Detector offers a promising set of features for both beginners and experienced treasure hunters. Its 12-inch coil is designed to cover a larger area, making searches more efficient. The IP68 rating ensures the coil is waterproof, allowing for shallow water searches, though the controller itself is not waterproof. This means it’s great for beach and shallow water use, but not suitable for fully submerged underwater metal detecting.

The device incorporates a new DSP chip that enhances accuracy and stability, which is useful when trying to locate objects up to 15 inches underground. It operates on a 9 KHz frequency which is decent for general metal detection but might struggle with very small targets or highly mineralized soils. With 5 detection modes, users can tailor their search for different types of metals, making it versatile for finding coins, jewelry, and gold. The discrimination mode is handy for filtering out unwanted metals, and the pinpoint mode helps in accurately locating the target, saving time.

The backlit LCD display, ergonomic design, and adjustable length enhance ease of use and comfort, which is a plus for extended search sessions. The included accessories like batteries, headphones, and a digger add value, making it a ready-to-go kit. However, the weight of 2.8 pounds might be a consideration for prolonged use, especially for younger users. To sum up, this metal detector is well-suited for hobbyists and enthusiasts who enjoy beach and shallow water metal detecting, although it may not meet the needs of those looking for a fully submersible underwater detector.

The DR.ÖTEK Metal Detector for Adults is geared towards both professional and hobbyist metal detecting enthusiasts. One of its strengths is its versatility with five upgraded modes, including a unique Memory Mode that helps you focus on detecting a specific metal type. This can save considerable time during searches. The large LCD display with backlight is easy to read and customizable, adding to its user-friendliness in various lighting conditions.

The 9.8-inch waterproof coil is a standout feature, allowing searches up to 10 inches deep and performing well in shallow water, making it suitable for beach outings or riverside adventures. The adjustable stem and 5-level sensitivity settings enhance comfort and effectiveness for users of different heights and experience levels. The device is lightweight at 2.2 pounds, promoting ease of use over extended periods without causing fatigue.

Accessories like a premium headset, digger shovel, and carrying bag add value and convenience, making this a thoughtful gift option. It's worth noting the operating frequency of 7 KHz, which is suitable for general metal detection but may not be as effective for detecting fine gold in mineral-rich soils. Additionally, the reliance on a 9V battery may require frequent replacements, depending on usage levels. Despite these minor drawbacks, the DR.ÖTEK Metal Detector offers a robust combination of features, especially for those looking to balance performance with ease of use.

The MINELAB MANTICORE Metal Detector Professional Bundle is designed for serious treasure hunters and includes everything you need for a successful hunt. The MANTICORE detector is highly powerful, boasting 50% more power than most models in its class, which allows it to find targets quickly and accurately even in tough conditions. It uses simultaneous multi-frequency technology, making it one of the most advanced detectors available. The 11-inch double D coil is a good size for covering a lot of ground while still being precise.

The waterproof feature is essential for underwater detection, and the IP rating suggests reliable protection against dust and water. The weight of 2.9 pounds and adjustable length make it user-friendly and ergonomic, allowing for extended use without discomfort. The included PRO-FIND 40 pinpointer is a standout addition, offering precise target location with minimal interference, which is especially useful underwater. The universal carry bag is practical for storage and transportation, ensuring that your gear stays in good condition.

A lithium-ion battery is included, offering a decent runtime, though you might need to monitor battery life closely during long sessions. One potential downside is the professional-grade features and price might be more than what a casual user needs. Additionally, its weight, while relatively light, could still become tiring for some users over prolonged uses. This bundle is ideal for dedicated hobbyists or professionals who need a reliable, high-performing metal detector capable of handling various environments, including underwater.
