Pappa Anton: Metal detectors

2011-9-14 · Very Low Frequency (VLF) detectors are the most versatile metal detector types, based on the range of metallic objects you can find with them. They are IB (Induction Balance) detectors using very low frequencies. As all IB designs, the VLF detector combines two balanced coils: the outer coil acts as a transmitter, using alternating current to create a magnetic field that is distorted by a ...
