two. Pulse Induction (PI) Detectors
PI detectors are typically used in demanding environments, such as seashores or saltwater areas. Compared with VLF detectors, PI detectors use just one coil to transmit and obtain indicators, emitting highly effective bursts of current that may penetrate deep into the ground. PI detectors are considerably less helpful at discriminating between metals but are ideal for locating buried objects in mineral-rich environments.
3. Beat Frequency Oscillation (BFO) Detectors
BFO detectors are the simplest sort and are sometimes found in entry-level or budget-friendly metal detectors. They use two oscillating frequencies, one particular created by a coil during the look for head and another by an inner reference oscillator. Each time a metallic item is detected, the frequency shifts, creating an audible sign to warn the person. On the other hand, BFO detectors are usually not as delicate or precise as VLF or PI detectors.
