What this set provides A simple metal detector set designed for basic metal detection tasks and hands-on learning. Key benefits — why you need it Quickly locate nearby metal objects for entertainment, basic security checks, or small searches. Serves as an educational tool to demonstrate and learn electronic circuit principles while using a working detector. Easy to use for beginners and suitable for low-complexity tasks where short-range detection is sufficient. Main functions and performance Metal detection: senses surrounding metal objects and indicates their presence. Detection distance: approximately 3–5.0 cm. Larger metal surfaces increase the effective detection distance; smaller or thinner objects reduce it. Designed for basic detection accuracy within the stated range. Use cases / practical applications Gaming and entertainment: scavenger hunts or hobbyist treasure-finding at home or small outdoor areas. Security checks: quick, short-range screening of pockets or small items at events or checkpoints. Educational demonstrations: classroom or workshop use to illustrate electronic circuit principles and how detectors respond to metal. Important attributes Function: metal sensing for locating nearby metal objects and demonstrating circuit behavior. Compatibility: suitable for uses including gaming entertainment, simple security checks, and targeted searches for metal objects. Size / performance: effective detection range of about 3–5.0 cm; detection distance varies with the size of the metal target. This product is a straightforward metal detector set intended for basic detection tasks and educational use, consistent with the supplied specifications and functions.
