While quite detailed and well written, I felt Bruce Candy's recent tome on detecting technology was a little beyond the theoretical grasp of the average detectorist. As I pondered what adventure breakfast was going to present this AM, it occurred to me that a cooking technology that has been around for a long time uses exactly the same principles as most modern detectors.
It is called Induction Cooking and embodies not only the same means of transmission, but has some crude forms of sensing the target(pan + contents). The stoves can "detect" when a pan is present to turn on & off, and can somewhat monitor how much material is in the pan. The stove has a coil similar to the detector, and the pan reacts to the current like the targets we search for. Interestingly they also operate at what in detecting circles is called VLF frequencies, i.e. 25KHz.
Here's a link that does a nice job of explaining the technology:
