Final Line:
“Inside the Metal Detector” is the closest thing to a repair manual and physics textbook for the dedicated treasure hunter. Read it once to stop guessing what your detector is telling you. Read it twice to start fixing and modifying them. The Transmit (TX) Coil: Located on the outer
- The Transmit (TX) Coil: Located on the outer perimeter, containing 50-200 turns of Litz wire. It radiates a primary magnetic field at a frequency between 3 kHz and 100 kHz.
- The Receive (RX) Coil: A smaller, inner coil with fewer turns. It is calibrated to ignore the direct magnetic field from the TX coil but generate a micro-voltage when eddy currents from a metal target disturb the field.
- The Faraday Shield: A layer of conductive foil (usually aluminum) with a single break to prevent electrostatic interference. The PDF schematic will show exactly where this shield connects to ground.
VLF (Very Low Frequency): The most common type; excellent for "discrimination" (telling the difference between a gold ring and a rusty nail).
