The DetectTrek MD-4070 is a kid-friendly metal detector built for easy learning, lightweight handling, and simple treasure hunting with an 8" waterproof coil.

Designed for beginners and younger explorers, the MD-4070 combines an intuitive LCD display, DISC filtering, and an extendable stem to make outdoor detecting straightforward and fun. It’s a starter-level tool that helps children understand metal signals quickly while letting families enjoy beach, park, and backyard hunts together. The detector balances durability and safety with ABS construction and a waterproof search coil suitable for shallow water and wet sand.

How does the MD-4070 make treasure hunting simple for kids?

The MD-4070 uses a clear LCD readout and simple controls so children can interpret signals without confusion. DISC mode helps filter common trash items, and the audible tones plus visual icon cues reduce guesswork for new users.

• Visible LCD icons show target type and signal strength.
• DISC setting lets kids ignore low-value metals like nails.
• Adjustable sensitivity reduces false alerts in noisy environments.

Can the detector be used at the beach or in shallow water?

The search coil is rated IP68 waterproof and can be submerged for locating items up to about 4 inches deep in soil, sand, and shallow streams. The control box itself is not waterproof, so the unit should be kept dry and only the coil immersed.

• 8" waterproof coil for wet-sand and shallow-water detecting.
• Best results when coil stays parallel to the ground.
• Keep the control box above water and dry during use.

Is this detector adjustable and built to grow with a child?

The telescoping stem extends from roughly 30" to 41", making it comfortable for children ages 8–12 and still useful for adults. Lightweight construction and child-safe ABS materials make handling easy and reduce fatigue on longer hunts.

• Extendable stem for ergonomic use as children grow.
• Lightweight design supports longer search sessions.
• Durable ABS plastic body for repeated outdoor play.

What practical tips help improve detecting success?

Following a few simple habits will improve finds and reduce frustration: use DISC mode at busy sites to skip iron trash, keep the coil parallel to the surface, and ensure batteries and cable connections are secure before heading out. Also maintain distance from other detectors to avoid interference.

• Activate DISC to reject iron objects at beaches and parks.
• Keep the coil level to the ground for consistent detection depth.
• Check battery installation and cable connection before each use.
