Product overview Simple metal detector set designed to detect surrounding metal objects and support basic electronic circuit learning. Key benefits — why you need it Detect metal quickly and simply: identifies nearby metal objects so you can locate lost items or check for metal in a target area. Educational value: the detector’s design and operation help demonstrate basic electronic circuit principles for students, hobbyists, and DIY learners. Versatile use cases: suitable for entertainment, basic security checks, and straightforward metal searches without complex setup. Main features Function: metal detection for surrounding metal objects and hands-on learning of electronic circuit behavior. Performance: detection range approximately 3–5.0 cm. The larger the metal surface, the greater the detection distance; smaller metal pieces will be detected at shorter ranges. Package: supplied as a simple metal detector set for immediate use in testing and demonstrations. Ease of use: straightforward operation for gaming, teaching, and security screening scenarios. Practical scenarios Classroom or home learning: use the set to demonstrate how circuits respond to nearby conductive materials and give students a practical introduction to electronics. Casual treasure hunt or gaming: detect small metal tokens or props during games and activities. Basic security or screening: perform quick checks for metal objects in backpacks, pockets, or small parcels where a compact, easy-to-use detector is appropriate. What it does not claim This is a simple, entry-level detector intended for short-range detection (3–5.0 cm) and educational or light-duty use. It is not marketed as a professional long-range or specialized metal-identification instrument. What’s included A simple metal detector set (as provided).
