VLF detectors are effective at distinguishing between unique metals, earning them helpful in pinpointing specific objects.
2. Pulse Induction (PI) Detectors
PI detectors are generally Utilized in hard environments, such as beach locations or saltwater places. Not like VLF detectors, PI detectors use one coil to transmit and obtain alerts, emitting powerful bursts of current which can penetrate deep into the ground. PI detectors are much less successful at discriminating in between metals but are perfect for locating buried objects in mineral-abundant environments.
3. Defeat Frequency Oscillation (BFO) Detectors
BFO detectors are The best kind and are often present in entry-amount or finances-friendly steel detectors. They use two oscillating frequencies, one generated by a coil from the search head and One more by an internal reference oscillator. Every time a metallic item is detected, the frequency shifts, creating an audible signal to alert the user. Even so, BFO detectors are not as delicate or specific as VLF or PI detectors.
four. Industrial Steel Detectors
