They are also helpful when it comes to troubleshooting, as they .
The inductor of the above tank circuit forms the detector of the metal detector (a large coil of wire). When metallic material approaches the center of the inductor (the detector coil), it enters the magnetic field created by the inductor. This changes the magnetic permeability of the inductor’s core, causing the inductance to change.

The Gemini-3 is our best ever. Search large areas fast: Use the easy, on-handle operation as shown or use it in the two-man, wide-scan search mode to find long objects or ore veins. In the wide-scan mode, two operators .The Beat-frequency oscillator (BFO) is the simplest (and oldest) type of metal detector technology and is a good starting point for learning how metal detectors work. The basic beat-frequency metal detector employs two radio frequency oscillators which are tuned near the same frequency. The first is called the search oscillator and the other is called the reference oscillator.
