The SUNPOW OTMD15 is a rechargeable, waterproof metal detector kit that locates coins, jewelry and small gold targets up to 10 inches deep with a 35-hour battery and precision pinpointer.

Whether you're beachcombing at low tide, exploring a park, or teaching a teen how to hunt for treasure, this all-in-one SUNPOW metal detector balances long runtime, saltwater-capable performance and beginner-friendly controls.

It also includes practical accessories like a shovel, headphones and a carry pack so you can head straight into the field.

How does the OTMD15 stay powered during long outings?

The detector uses a 2500mAh Li-ion battery that delivers up to 35 hours of continuous scanning on a single charge, so you can spend full days detecting without frequent recharges. USB-C fast charging shortens downtime and built-in overcharge protection protects battery health.

• 2500mAh high-capacity battery for extended sessions
• USB-C fast charge for quick turnaround between outings
• Overcharge protection to preserve long-term battery life
• LED battery indicator on the backlit LCD

Can I use this detector at the beach or in saltwater?

Yes — the OTMD15 comes with an IP68-rated, fully submersible 11-inch dual-D coil that reduces mineralized sand and saltwater interference. That design improves target separation and makes it easier to find jewelry and coins in wet sand, shallow surf and creeks.

• IP68 waterproof coil suitable for shorelines and shallow water
• Dual-D coil geometry for better noise rejection in mineralized ground
• Discrimination settings to avoid common trash targets on beaches
• Works with included headphones to hear faint tones over waves

What search accuracy and modes are available?

The detector offers four operation modes — All-Metal for maximum depth, DISC and NOTCH for discriminating unwanted targets, and a Pinpointer mode to quickly zero in on finds. The backlit LCD supplies visual target ID and depth estimates so you can decide whether to dig.

• All-Metal for deepest detection range up to about 10 inches
• DISC and NOTCH to filter junk and focus on desirable targets
• Pinpointer mode reduces digging time and disturbance
• Backlit LCD shows conductivity estimates and shallow/deep cues

Is the detector comfortable and easy to adjust for different users?

Yes — the telescoping shaft adjusts from 19" to 51" to fit children and adults up to about 6 feet tall. The lightweight, ergonomic armrest and quick-lock system keep the search coil stable for fatigue-free hours of scanning.

• Tool-free length adjustment suits families and taller users
• Quick-lock shaft eliminates wobble during sweeps
• Lightweight construction for comfortable all-day use
• Padded handle and armrest for improved control and comfort

Who this is for: The SUNPOW OTMD15 targets hobbyists, families and newcomers who want a ready-to-use detector that performs well at beaches, parks and backyard sites. It's a practical gift for teens and adults who value long battery life, waterproof capability and included accessories that remove the guesswork when starting a treasure-hunting hobby.
