How Metal Detectors Work | HowStuffWorks
A typical PI-based metal detector sends about 100 pulses per second, but the number can vary greatly based on the manufacturer and model, ranging from a couple of dozen pulses per second to over a thousand. If the metal detector is over a metal object, the pulse creates an opposite magnetic field in the object.

How Do VLF Metal Detectors Work – MetalDetector
This type of VLF detector sends out signals across multiple frequencies simultaneously. VLF metal detectors send out a low-frequency signal that is then reflected back to the detector when it comes into contact with metal. The strength of the signal depends on the type of metal and its conductivity. VLF machines are good at detecting a small ...

I don't understand the working principle of this metal detector circuit?
The inductor serves as a "sensor" to detect metal. The tone of the speaker changes when a metal is detected. However, I don't know anything about how the circuit works internally. I can only do the circuit connection. Please can someone explain how how the internal circuit of the 555 time makes this possible? What mode is the IC operating?
