hazlewolke Underwater Metal Detector – 130 ft Waterproof 10" Coil, Pinpoint Mode & Saltwater Corrosion Protection

Hazlewolke WP6027 is a professional-grade waterproof metal detector built to search down to 130 feet (40 m) with pinpoint accuracy and adjustable discrimination for underwater and shoreline treasure hunting.

Designed for divers and coastal prospectors, the WP6027 combines a corrosion-resistant housing, ultra-low frequency detection, and a clear audio/LED feedback system so you can focus on recovery instead of guesswork. Its 10" search coil and 2.4 kHz operating frequency increase penetration in wet, mineralized ground and underwater environments, while user controls let you tune sensitivity and ignore common trash. Below you’ll find practical answers to the top questions buyers ask when choosing a capable underwater detector.

How deep and durable is this detector for diving and beach use?

The WP6027 is engineered to remain watertight to 130 ft (40 m) with seals and materials treated to resist saltwater corrosion. The full assembly — including coil, control housing, and cable — is built to withstand repeated submersion and the wear of marine conditions.

• Waterproof rating: 130 ft / 40 m depth tolerance
• Saltwater corrosion protection on exposed components
• Robust 10" search coil suitable for underwater swells and sand
• Durable build for beach, lake, and river use

What kind of targets will it detect, and how does the feedback help identify them?

Operating at an ultra-low 2.4 kHz, the detector excels at deeper penetration and finds a wide range of metal types including coins, jewelry, and larger relics. The combined audio tones and LED color cues give instant, intuitive hints: low-pitched tones with red flashes indicate low-conductivity items, while high-pitched tones and blue flashes point toward higher-conductivity targets like gold or silver.

• 2.4 kHz frequency for improved depth on larger targets
• Audio tones plus blue/red LED indicators for fast assessment
• Useful in both freshwater and saltwater environments
• Pinpoint mode refines exact location before recovery

How do sensitivity and discrimination controls improve my search efficiency?

The Hazlewolke WP6027 offers adjustable sensitivity to detect smaller or deeper items and a discrimination mode to filter unwanted junk. Increase sensitivity when hunting for tiny artifacts or reduce it in noisy environments; set discrimination to ignore common trash like nails or bottle caps so you spend less time digging and more time retrieving valuables.

• Variable sensitivity for deep or small-target detection
• Discrimination settings to exclude unwanted target types
• Pinpoint function narrows down exact find location quickly
• Practical presets for beach, freshwater, and mineralized soil

Can I use this detector on land as well as underwater?

Yes — the WP6027 is a versatile detector that performs well on beaches, riverbanks, lakeshores, and mineralized soils as easily as it does submerged. Its construction and electronics are tuned for both wet and dry conditions, making it a single solution for mixed-terrain prospecting trips.

• Works effectively in wet sand, muddy riverbeds, and dry soils
• Reliable recovery performance in both salt and freshwater
• One device for divers and shoreline hunters alike
• Easy to switch between modes for different environments

Who is this for: The Hazlewolke WP6027 is aimed at recreational divers, beachcombers, and serious hobbyists who want a rugged, deep-search-capable metal detector that tolerates saltwater and gives clear, actionable feedback. If you need a single, durable detector that handles underwater depths, mineralized beaches, and rivers while offering sensitivity control and pinpointing features, the WP6027 is built to meet those needs.
