  • Metal Detector Guide For Beginners with Detectors Direct

    How do VLF Metal Detectors Work VLF metal detectors use a two coil detection system to detect objects. One coil sends a signal out into the ground and the second coil receives it. The first coil which we call a sender coil pushes the signal into the ground and creates a magnetic field which reacts to any metallic objects beneath the surface
