Simple metal detector kit with 3-5.0 cm detection range. Detects nearby metal objects and doubles as a hands-on learning tool for basic electronic circuit principles. Larger metal areas are detected at greater distances. Key benefits Reliable short-range detection: Detects metal objects from approximately 3-5.0 cm; detection distance increases with larger metal surfaces. Practical and educational: Useful for entertainment and security applications while also demonstrating basic electronic circuit behavior for learning and experimentation. Easy to use: Designed as a simple kit so users can assemble, operate, and observe detection behavior without advanced tools. What it does Metal detection: Locates nearby metal objects in the surrounding area and indicates presence for searching or inspection purposes. Educational function: Offers a straightforward way to explore how metal detection circuits react to different metal sizes and positions. Important attributes Function: Metal detection for gaming, security checks, and object searching; educational circuit demonstration. Performance: Detection range about 3-5.0 cm; larger metal areas yield further detection distance. Compatibility: Effective on a variety of metal objects; performance depends on metal size and orientation. Kit format: Supplied as a simple metal detector kit for assembly and hands-on use. Use scenarios Gaming and family fun: Treasure hunts and outdoor games where children and adults search for small metal items hidden in sand or grass. Security and inspection: Quick, informal security checks or locating small metal objects in tight spaces where larger detectors are impractical. Classroom or hobby electronics: Demonstrate and explore basic electronic circuit principles by observing how the detector responds to different metal sizes and positions. What’s included Simple metal detector kit (components for assembly provided). Who this is for Hobbyists, educators, parents, and event organizers who need a compact, low-range metal detection tool that also serves as an educational demonstration of electronic circuits. Notes on use Detection distance varies by metal size, shape, and orientation; larger metal areas produce greater detection distance. Intended for short-range detection and learning purposes rather than long-range professional locating tasks.
