How Metal Detectors Work
Metal detectors are fascinating devices that have a wide range of applications, from hobbyist treasure hunting to professional gold prospecting and security screening. Understanding how these machines work can help you choose the right one for your needs and maximize your success in the field. Whether you're considering models like the Gold Monster 1000 or the Equinox 900, knowing the basics will guide you in making the best choice among the metal detector 1. The Basic Principle of Metal Detection At its core, a metal detector works by generating an electromagnetic field through a coil, which is then transmitted into the ground. When this electromagnetic field encounters a metal object, it induces a current in the metal, which in turn creates its own magnetic field. The metal detector's coil detects this secondary magnetic field and sends a signal to the control unit, which interprets the signal as the presence of metal. This is the basic principle behind ...
