VLF detectors are able to distinguishing amongst distinct metals, making them helpful in pinpointing certain objects.
2. Pulse Induction (PI) Detectors
PI detectors are typically Employed in demanding environments, like beach locations or saltwater areas. Not like VLF detectors, PI detectors use only one coil to transmit and acquire indicators, emitting powerful bursts of present-day which can penetrate deep into the bottom. PI detectors are significantly less productive at discriminating concerning metals but are ideal for finding buried objects in mineral-wealthy environments.
3. Defeat Frequency Oscillation (BFO) Detectors
BFO detectors are The only type and in many cases are found in entry-stage or price range-helpful steel detectors. They use two oscillating frequencies, a single produced by a coil in the lookup head and A further by an inside reference oscillator. When a metallic object is detected, the frequency shifts, causing an audible signal to inform the user. Nevertheless, BFO detectors will not be as sensitive or exact as VLF or PI detectors.
