VLF detectors make use of a sensor coil and transmitter coil. The transmitter coil emits constant electromagnetic energy at a tuned frequency. When this Electrical power encounters metal underground, it creates an eddy current in the metal that leads to a period shift from the reflected frequency. The sensor coil is then in a position to read this period-shifted frequency pattern.
