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.\n\n\u003ch3\u003eHow deep and where can this detector find targets?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWaterproof 7.4\" coil for surf and shore scanning\u003c\/li\u003e\n  \u003cli\u003eDetects small coins and jewelry down to roughly 6 inches\u003c\/li\u003e\n  \u003cli\u003eThree detection modes to tailor sensitivity by ground conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat features make it easy for kids to use all day?\u003c\/h3\u003e\n\u003cp\u003eThe 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.
