[QUOTE="steelPHASE, post: 530643, member: 13488"] The title of the post is about a GPX so I assume he also has a VLF machine as well as the GPX. VLF machines already have discrimination and the audio coming out is post processing and often has already been processed to indicate target composition. The pulse waveforms Woody shows are not whats coming out of the detector. They are what is going into the coil. In a VLF its basically just a sine wave going into the coil. A great book thaat goes into some depth on detectors and how they work is called "inside the metal Detector" and is written by Carl Moreland from over on the Geotech forum (he used to work for Whites and now is with First Texas). regards Pat [/QUOTE]
