BASIC CIRCUITRY of Metal Detection - Talking Electronics

The Metal Detector MkII front-end changes amplitude when metal is detected and the remainder of the circuit amplifies this change and produces a tone. Circuit 8 produces a change in frequency. If we want to detect the first sign of change-in-frequency, we need to have two oscillator operating at exactly the same frequency and detect the difference.
