People wanting to build a high-performance detector from scratch. Engineers looking to understand the core physics of

BFO is the simplest form of metal detection technology, often used in entry-level or DIY kits. Uses two separate oscillators to create an audible beat. Frequencies shift when the search coil passes over metal. BFO is the simplest form of metal detection

PI detectors send powerful, short bursts of current through a single search coil. Measures the speed of the decaying magnetic field. Ignores ground mineralization almost entirely. Lacks the advanced target discrimination of VLF machines. 3. Beat Frequency Oscillation (BFO)

Without canceling out ground mineralization, depth is severely limited.
