Instructions for an off-resonance pinpointer, a GEB-discriminator, and a PI detector. Hands-on Learning:
: BFO (Beat Frequency Oscillation), TR (Transmit-Receive), and PLL (Phase-Locked Loop). Hands-on Projects
So, what happens inside a metal detector? The basic principle of a metal detector is simple: it uses an electromagnetic field to detect the presence of metal objects. Here's a simplified overview of the process:
