10 Best Salt Water Metal Detector 2026 in the United States

The MINELAB MANTICORE is a standout choice for anyone looking to explore the world of salt-water metal detecting. Its Multi-IQ+ technology delivers impressive performance, offering 50% more power than many traditional models. This feature is particularly beneficial in challenging environments like beaches where multiple frequencies can help detect various types of metals effectively. The advanced target ID system enhances the user experience, providing visual and audio feedback that aids in distinguishing valuable targets from junk, making it easier for treasure hunters to find what they’re looking for.

One of the key highlights of this detector is its waterproof capability, rated at IP68, allowing it to be submerged up to 16 feet. This makes it ideal for surf and seawater detecting, ensuring users can confidently search without worrying about water damage. With 10 different search modes, it accommodates a range of terrains, from sandy beaches to inland areas, which adds versatility to its usability.

The MANTICORE is also designed with user comfort in mind; it’s lightweight at just 7.1 pounds and features an adjustable length, making it easy to carry and use for extended periods. Customizable audio controls and backlit features ensure that you can detect in various lighting conditions, adding to its practicality. Potential buyers should consider a couple of drawbacks. While the advanced features make it powerful, they may also present a learning curve for beginners. If you’re new to metal detecting, it might take some time to fully understand all the options and settings. Additionally, while it’s lightweight, some users may still find it cumbersome during long hunts.

The MINELAB MANTICORE is a robust metal detector catering to both seasoned treasure hunters and those willing to invest time to learn its features, particularly in salt-water environments. Its strengths in power, waterproofing, and ease of use make it a worthy option, though those new to the hobby might need to dedicate some time to master its advanced functions.

The MINELAB Equinox 900 Multi-Frequency Metal Detector is a versatile tool for salt-water metal detecting. One of its standout features is its multi-frequency technology, allowing operation at six different frequencies, which enhances its ability to detect various types of metals in different conditions. It's fully waterproof and submersible up to 16 feet, making it ideal for underwater searches at beaches or riverbanks. The EQX 15 Double-D Waterproof Smart Coil is particularly useful for covering large areas efficiently.

Ground balance options and discrimination modes, like Park, Field, Beach, and Gold, help customize searches according to specific environments or targets, providing accurate target identification with up to 119 high-resolution IDs. The built-in flashlight and handgrip vibration are thoughtful additions for low-light conditions and improved usability. Ergonomically, its lightweight design (2.8 lbs) and collapsible structure make it easy to carry and handle, reducing fatigue during prolonged use.

However, the operating frequency is fixed at 5 KHz, which may not be as effective for certain metal types compared to higher frequencies. Despite this minor drawback, the MINELAB Equinox 900 is a strong choice for hobbyists looking for a reliable and flexible metal detector for salt-water environments.

The Minelab EQUINOX 800 bundle is a strong choice for salt-water metal detecting thanks to its advanced Multi-IQ technology, which uses 5 frequencies simultaneously to work well in various soil and water conditions, including salty environments. Its operating frequency around 5 kHz is versatile for detecting different metals, while the adjustable ground balance helps reduce interference typical of saltwater beaches. The included 6-inch double-D coil is waterproof and designed for pinpointing small targets even in trashy or tough terrain, making it ideal for beach or riverbed hunting.

Both the detector and coil are fully submersible up to 10 feet (about 3 meters), so you can confidently search in shallow saltwater and wet soil without worry. Weighing just under 3 pounds, the detector is relatively lightweight and collapsible, offering good comfort and portability during extended use. It also features discrimination settings and 8 programs to help distinguish valuable finds from junk.

Some users might find the price higher than entry-level models, and while the 6-inch coil is great for precision, it might cover less ground than larger coils on open beaches. Additionally, beginners may need some time to fully understand the multiple settings to get the most out of it. This bundle suits both hobbyists and serious treasure hunters looking for a reliable, user-friendly metal detector for saltwater environments.
