Phase shift provides VLFbased metal detectors with a capability called discrimination. Since most metals vary in both inductance and resistance, a VLF metal detector examines the amount of phase shift, using a pair of electronic circuits called phase demodulators, and compares it with the average for a particular type of metal. The detector ...
· A VLF metal detector fits the bill. The best beginner metal detectors should cost between 150 to 300. They should offer a digital display, a few search modes, discrimination, be lightweight and portable, and have included accessories to get detecting out of the box.
