Little adventurers can look forward to big discoveries while searching with the children's metal detector, featuring a waterproof search coil and LCD display. The metal detector is adjustable in length and features an ergonomic handle. It has an acoustic signal and emits a light when it detects metal. Go on a discovery tour! With the NATIONAL GEOGRAPHIC metal detector for kids, you can discover metal objects hidden underground. You can make interesting finds in many places in the garden or at the playground. A real sleuth! You can start your adventure right away with the metal detector because it's so easy to use: Turn on the metal detector and slowly swing the search coil back and forth, about 2 cm above the ground. If a metal object is found underneath, at a depth of up to 12 cm, you'll hear a beep and a light by the handle will come on. The LCD screen also displays an icon when you've found something. Perfect for large puddles and narrow streams: Since the coil is waterproof up to 15 cm, you can also search in small waters.
