PI detectors are usually used in complicated environments, which include shorelines or saltwater areas. As opposed to VLF detectors, PI detectors use an individual coil to transmit and receive alerts, emitting strong bursts of existing that may penetrate deep into the bottom. PI detectors are considerably less successful at discriminating in between metals but are ideal for finding buried objects in mineral-abundant environments.
3. Conquer Frequency Oscillation (BFO) Detectors
BFO detectors are the simplest form and are sometimes found in entry-stage or price range-welcoming metal detectors. They use two oscillating frequencies, one 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, resulting in an audible sign to notify the consumer. Even so, BFO detectors usually are not as delicate or precise as VLF or PI detectors.
