Jan 14, 2013· Thecircuitthey're talking about in this thread is not a receiver, it is a transmitter that has no useful function. Has nothing to do withmetaldetection, nothing to do with mineral detection, nothing to do with atmospherics, no practical use whatsoever. Even as an example of a 555 oscillatorcircuit, it's one of the worst I've seen.
