GDDREAM Underwater Metal Detector Pinpointer — IP68 98ft Waterproof, Rechargeable 30-Hour Battery

Designed for beachcombers, river explorers and scuba divers, this compact detector combines straightforward controls with deep waterproofing and long battery life. Lightweight and rugged, it’s made to handle wet conditions and strong surf while helping you zero in on targets with sound, vibration and LED cues. The unit is beginner-friendly yet robust enough for frequent use on land and underwater.

How deep can I take this detector and what environments does it handle?

The GDDREAM pinpointer meets IP68 waterproofing and is rated for operation down to 98 feet (30 meters), so it’s suitable for snorkeling, freediving, and many recreational scuba uses. On land it performs well in sand, soil and grassy areas thanks to its sealed construction and impact-resistant ABS body.

• Fully submersible to 98 ft (30 m) for underwater searching.
• Sealed ABS housing resists sand and saltwater corrosion.
• Compact 16.6" length and 6" search coil for tight spots.
• Also works on beaches, rivers, parks, and shallow water.

How do I operate it and choose alert modes?

Operation is intentionally simple: two buttons power the unit and toggle modes so you can start searching quickly without a learning curve. Press-and-hold lets you cycle through sound, vibration, or a combined sound-plus-vibration mode, and an LED provides clear visual guidance when visibility is poor.

• Two-button layout for fast on/off and mode switching.
• Choose sound, vibration, or both for different conditions.
• LED targeting helps locate items in murky water or at night.
• Buttons sealed for waterproofing—press firmly to operate.

What about battery life, charging, and lost-device features?

The detector has a built-in 1600mAh lithium battery that recharges in roughly four hours and can run up to 30 hours per charge, making it dependable for long trips. A built-in lost alarm activates after about ten minutes of inactivity, emitting sound, vibration and strobing LED to help you relocate the unit in sand, seaweed or low-visibility water.

• 1600mAh rechargeable battery — fast charging in ~4 hours.
• Up to 30 hours runtime on a single charge for extended outings.
• Automatic lost alarm after 10 minutes of no operation.
• No disposable batteries required—USB charging for convenience.

What kinds of targets can it find and how precise is the pinpointing?

The GDDREAM detector is optimized for locating small metal objects like coins, rings, jewelry and small relics. The combination of audio cues, vibration feedback and LED targeting helps you narrow down a target quickly, even in noisy surf or when you need to remain quiet while searching.

• Designed for coins, rings, small jewelry and relic fragments.
• Triple-alert system improves target confirmation and precision.
• 6" search coil balances coverage with focused detection.
• Helpful for tight spots, crevices, and undersea debris fields.

Who is this for? The GDDREAM Underwater Metal Detector is ideal for recreational divers, beach treasure hunters, and outdoor hobbyists who want a reliable, easy-to-use pinpointer that performs both on land and well below the surface. If you value long battery life, clear feedback modes (sound, vibration, LED), and a truly submersible design for deeper water searches, this detector offers a practical, travel-friendly solution. Note that the waterproof buttons require a firmer press due to the sealed build; follow the instructions to power on in open air before submersion.
