— At its most basic, a gold detector circuit diagram consists of two main components; a receiver and a transmitter. The receiver is placed at a distance from the signal source, typically in the form of a digital transceiver.

BASIC PRINCIPLES. Metal detectors work by transmitting an electromagnetic field from the search coil into the ground. Any metal objects (targets) within the electromagnetic field will become energized and retransmit an electromagnetic field of their own.

How Do Metal Detectors Work: A Simple Explanation. Notice the "red" signal pattern being transmitted from the metal detector coil into the ground. (Note: we have enlarged the illustration of the signal pattern for easier understanding).

 — A deep gold detector circuit diagram is made up of several components that are wired together in a specific pattern to increase the functioning capabilities of a metal detector.

 — When a metal detector's magnetic field interacts with a metal object, it induces small circular electric currents (eddy currents) in the metal, which create their own magnetic fields and can be detected by the receiver coil. Different sizes, shapes, textures, and materials of objects can disrupt the magnetic field.

 — An easy-to-understand explanation of metal detectors, including an animation showing how they work and photos of different kinds of metal detectors in action.

Gold detectors work by transmitting an electromagnetic field into the ground. This field transmitted induces loops of electrical current, known as eddy currents, within conductive materials or metals.

Metal detectors can help you find metal buried deep in the ground. Find out how metal detectors work and learn about the different types of metal detectors.
