Example VLF design: Heathkit Groundtrack GR-1290 VLF metal detector. Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object.
