Inside The Metal Detector George Overton Carl Moreland.pdf [hot] Online

BFO is the simplest and oldest form of metal detection technology.

The digital manual remains highly sought after in the maker community for several distinct reasons:

It uses two radio frequency oscillators. One is fixed, and the other uses the search loop as its tuned circuit. The two frequencies mix, producing an audible beat note. When the loop passes over metal, the frequency changes, altering the pitch of the tone. Inside The Metal Detector George Overton Carl Moreland.pdf
