I have been doing some research for my own education on metal detector types. You will or have noticed I use patents and frankly it takes a strong background in electronics to wade through the material for the more informative patents as you guys know. The patents are the only information I have found where manufacture will come close to sharing what ever it is that is behind the veil of secrecy for the process they use. This sounds confusing because there is nothing new about the technology, solid state devices, analog, and the like but how the technology is deployed so I call it process. I guess one really has to be a serious electronic geek or engineer to give a whit about how the technology fits together to do what it does. I have always been the type to destroy anything mechanical or electronic just to see how it worked which was a constant irritant to my parents when as a kid I destroyed just about every clock in our home to see how they worked and if I could reassemble them so that they worked. Most of my toys were the entrails of victims of my curiosity of how "things" worked.
Metal detector fall into two classes, time domain and frequency domain as you know. We all are familiar with a right triangle so if we start with our arm pointed straight out and consider that as zero (0) and rotate the arm to straight over our head and consider that as ninety (90) degrees we have a nice reference. Let
