Hi, I have a few questions. 1. Suppose I use a single frequency of 20kHz. If I do that, would I be able to detect only certain metals or would the detector still pick up all metals? If it would still pick up all metals, would the signals from some of those metals be weaker (quieter)...

I have read where some hunters noise cancel with the coil on the ground to get a better reading from the ground. Any thoughts on this technique? Anyone using this method for noise canceling. The theory being that better you ground balance and noise cancel along with lowering the sensitivity the...
