VLF detectors are effective at distinguishing between various metals, producing them powerful in determining unique objects.
two. Pulse Induction (PI) Detectors
PI detectors are generally Utilized in demanding environments, for instance beach locations or saltwater destinations. Compared with VLF detectors, PI detectors use only one coil to transmit and acquire alerts, emitting highly effective bursts of latest which will penetrate deep into the bottom. PI detectors are considerably less powerful at discriminating amongst metals but are ideal for locating buried objects in mineral-abundant environments.
3. Beat Frequency Oscillation (BFO) Detectors
BFO detectors are The only sort and are frequently found in entry-amount or finances-pleasant metal detectors. They use two oscillating frequencies, a person produced by a coil inside the search head and A further by an inside reference oscillator. Whenever a metallic item is detected, the frequency shifts, triggering an audible signal to notify the user. However, BFO detectors are certainly not as sensitive or specific as VLF or PI detectors.
