metal detector

Description

A metal detector is a handheld electronic device designed to detect the presence of metal objects hidden beneath the ground, inside walls, or under other surfaces. It works by emitting an electromagnetic field through a search coil, which reacts when it comes into contact with metal, producing a sound or visual signal to alert the user. Metal detectors are commonly used for treasure hunting, archaeology, security screening, and construction work to locate buried pipes, cables, or other metallic items. Most modern models feature adjustable sensitivity, depth detection, and discrimination settings to distinguish between different types of metals, making them highly efficient and easy to use for both beginners and professionals.
