Dive Into Treasure Hunting with Underwater Metal Detectors – Only at Detector Hero

All set to explore under the surface your metal detecting excursions? Our selection of underwater metal detectors at Detector Hero is meant to investigate rivers, lakes, seas, and all points in between. Whether your preferred activity is shallow water waders, beach hunting, or scuba diving, we have waterproof detection equipment to literally help you find gold.

Why Choose an Underwater Metal Detector?

Not designed to handle water are standard detectors. But waterproof and totally submersible metal detectors are designed to function where others fall short. These detectors are made to retain sensitivity, depth, and signal accuracy even underwater from salty waves to freshwater streams.

An underwater detector introduces a whole new realm of detecting possibilities whether your quest for missing jewels in the shallows or diving for historical relics.

Key Features to Look For:

  • Fully Submersible Designs: Rated for depths ranging from 10 feet to 200 feet.

  • Saltwater-Optimized Performance: Stable operation in high-mineralization environments.

  • Pulse Induction & VLF Technology: Choose the right tech for your target and terrain.

  • Waterproof Headphones & Control Units: Stay connected and in control underwater.

  • Lightweight & Balanced: Designed for extended underwater use without fatigue.

Top Brands You Can Trust

We carry the best from the industry—Minelab, Garrett, Nokta, and XP. From the Garrett Sea Hunter and Minelab Excalibur II to the Minelab GPX 6000, every model is field-tested and reliable by dives and beach hunters all around.

Perfect for:

  • Beach & Surf Detecting

  • Scuba Diving

  • Shallow Water Wading

  • Riverbed Exploration

  • Boatside Recovery Missions

Gear Up and Get Wet

Allow your hunt to be unrestricted by the shore. Underwater metal detectors from Detector Hero let you search smarter, explore farther, and find treasures others overlook.
