Though considered an older, less sensitive technology, BFO is the perfect starting point for beginners. The book explains how BFO utilizes two radio-frequency oscillators: a fixed reference oscillator and a search loop oscillator. When the search loop approaches metal, its inductance shifts, altering the frequency. The circuit mixes these two frequencies, generating an audible "beat" note that changes pitch. Overton and Moreland provide simple schematics to help novices understand basic tank circuits and frequency stability. 2. Induction Balance / Very Low Frequency (VLF)

One of the most significant legacies of Overton and Moreland is their emphasis on responsible metal detecting practices. Both individuals have stressed the importance of respecting the environment, private property, and historical sites. Their advocacy for responsible metal detecting has helped to promote a positive image of the hobby and has encouraged enthusiasts to adopt best practices.
