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 …

Early VLF detectors that had discrimination were only low frequency in the all metal mode. George Paine developed a circuit that could run in discrimination at a VLF frequency. The catch was that you had to really move the coil for it to work properly. The detector was the Bounty Hunter Red Baron. All manufacturers now use some form of that ...
