What this product does A simple metal detector kit that detects nearby metal objects and doubles as a hands-on learning tool for basic electronic circuit principles. Detection range: approximately 3–5.0 cm. Larger metal surfaces increase the effective detection distance. Key benefits — why you need it Learn and build: Ideal for students and hobbyists who want a compact, practical project to understand how electronic detection circuits work. Practical detection: Quickly locate small metal objects and confirm presence of metal in a controlled, short-range area. Versatile use: Serves both educational and practical needs without complex setup. Important attributes Function: Metal detection with clear, short-range sensitivity (3–5.0 cm). Kit contents: Supplied as a simple metal detector kit ready for assembly and demonstration. Performance: Reliable response within the specified range; sensitivity improves with larger metal areas. Compatibility: Works with common metal objects and integrates easily into classroom exercises, DIY projects, or basic field checks. Size/material: Compact kit suitable for hands-on use; components designed for learning and light-duty detection tasks. Typical applications Classroom lab: Demonstrate electromagnetic detection and circuit behavior in physics or electronics lessons. Hobby & gaming: Use for treasure-hunt games, model-making checks, or small-item searches at events. Basic security or quick checks: Fast, portable screening for small metal items in bags or pockets where short-range detection is sufficient. Why it stands out Combines a practical metal detector with an educational electronics kit, delivering immediate demonstration value and everyday utility in a simple, portable package. Includes: a simple metal detector kit for assembly and use. Detection range: 3–5.0 cm (larger metal areas produce greater detection distance).
