VLF detectors are able to distinguishing concerning different metals, earning them powerful in identifying particular objects.
two. Pulse Induction (PI) Detectors
PI detectors are typically used in complicated environments, which include seashores or saltwater spots. Unlike VLF detectors, PI detectors use a single coil to transmit and acquire signals, emitting highly effective bursts of existing that will penetrate deep into the bottom. PI detectors are less powerful at discriminating involving metals but are ideal for locating buried objects in mineral-rich environments.
three. Defeat Frequency Oscillation (BFO) Detectors
BFO detectors are the simplest style and are often located in entry-degree or budget-welcoming steel detectors. They use two oscillating frequencies, 1 created by a coil while in the lookup head and another by an inside reference oscillator. Whenever a metallic item is detected, the frequency shifts, leading to an audible sign to inform the person. Having said that, BFO detectors will not be as delicate or exact as VLF or PI detectors.
