Blue Marble National Geographic Kids Metal Detector – 7.4" Waterproof Coil, Lightweight with Pinpoint & LCD

Blue Marble's National Geographic metal detector for kids is a lightweight, adjustable treasure-hunting kit with a 7.4" waterproof coil, pinpoint mode, LCD display and easy-to-use controls for beach and backyard detecting. This detector combines a durable waterproof search coil with kid-friendly ergonomics and clear visual feedback, so young explorers can find coins, relics and small metal objects with confidence. It balances sensitivity and simplicity: three detection modes help beginners learn discrimination while the pinpoint function narrows targets for faster recovery. Included accessories — a trowel and a Learning Guide — turn each outing into a short STEM lesson about metal detecting and local history.

How deep and where can this detector find targets?

The 7.4" dual search coil can detect metal objects buried up to about 6 inches depending on soil and target size. Because the coil is waterproof, you can sweep shallow surf lines, wet sand or muddy shorelines, expanding where kids can search safely under supervision.

• Waterproof 7.4" coil for surf and shore scanning
• Detects small coins and jewelry down to roughly 6 inches
• Three detection modes to tailor sensitivity by ground conditions

What features make it easy for kids to use all day?

The detector is designed for younger users: it weighs about 1.4 pounds and includes a telescoping arm with a comfortable grip and adjustable length so children of different ages can hold it correctly. The LCD screen and simple controls show target signals clearly, while the lightweight build reduces fatigue during longer hunts.

• Adjustable telescoping shaft to fit different heights
• Comfort grip and balanced weight for extended use
• Large LCD for numeric and visual target feedback

How does the pinpoint function help find buried items faster?

After the detector signals a potential find in coarse sweeps, switch to pinpoint mode to focus the electromagnetic field and identify the exact location before you dig. This reduces unnecessary digging and protects fragile finds because you remove less material once the target is isolated.

• Pinpoint mode narrows the target area for precise digging
• Saves time and minimizes hole size when recovering objects
• Useful on crowded beaches or lawns with many small items

What comes in the kit and how will it support learning?

The package includes the detector, a digging trowel and a Learning Guide that explains basic techniques and the history behind metal detecting. These elements turn each outing into a mini lesson in observation, patience and local discovery — ideal for family activities and outdoor education.

• Includes trowel for safe, controlled digging
• Learning Guide covers technique and detector care
• Simple setup gets kids detecting quickly with parental oversight

Who is this for? This kit is aimed at children and families who want an accessible, hands-on introduction to metal detecting without the complexity of adult-grade machines. It's well suited for beginners who will use it at beaches, parks and backyards and for educators looking for an outdoor STEM activity. If your priority is a lightweight detector with clear feedback, adjustable sizing, and a waterproof coil for shoreline searching, this Blue Marble National Geographic model delivers a balanced combination of durability, ease of use and educational value.
