When you open a quality "Inside the Metal Detector" technical PDF, you should expect to see four distinct sections.

When opening a technical PDF or blueprint of a metal detector, you will encounter several critical stages in the circuit diagram: inside the metal detector pdf

The coil is not a single loop of wire. Inside a typical VLF concentric coil (like the classic White's or Garrett designs), the PDF reveals:

When a metal object passes by, its own induced magnetic field disrupts the receiver coil. The machine measures the phase shift to determine the type of metal (discrimination). Pulse Induction (PI) When you open a quality "Inside the Metal

When the transmitter's magnetic field hits a metal object, the object's resistance and inductance cause a time delay in the returned secondary field. This time delay is called a phase shift.

Excellent target discrimination (can tell iron apart from gold); highly energy efficient. The machine measures the phase shift to determine

The technology can be broken down into several key subsystems:
