Search dry ground, shorelines, and underwater areas with the National Geographic 80-20010 Underwater Metal Detector. Its lightweight handheld design is waterproof to depths up to 32 feet, giving treasure hunters one tool for beach, river, stream, yard, and water exploration. Automatic sensitivity keeps operation straightforward while the detection coil responds to metal targets such as coins, jewelry, and other precious metals.

Light and Pulse Targeting

When the coil detects a target, a bright LED light and vibration provide clear feedback. The number of pulses rises as the coil moves closer to the target, and pulse quantity also responds to target size. Sweep the coil back and forth across the search area, then move away and approach again to narrow the location. Automatic sensitivity supports the search while light and pulse cues help you follow the detector response.

Ready for Water-Based Searching

The detector can be used underwater to a depth of 32 feet. An attached wrist strap helps keep the detector secure while searching. Before submerging the unit, confirm the battery compartment seal is secure, and the O-ring is present. After saltwater use, rinse the search coil with fresh water and dry it thoroughly to help prevent corrosion of metal parts.

The detector runs on 1 x 9-volt battery, which is not included. If no metal is detected for one minute, the unit shuts off automatically. The unit also shuts down automatically when battery power is low. For new users, practicing with known targets can help build a consistent sweeping technique before heading to the beach or water.
