I wish all questions were this easy to answer.
Answer: Tune any standard BFO-type detector to the slowest difference frequency possible (just barely ticking), then wave it around at a distance of 1 meter from a metal coin. Note that the "ticking" changes frequency ever so slightly, indicating "something" at the 1 meter distance. Of course the results will be inconsistent at best and might be influenced by temp, humidity and ground mineralization; but then so are the results from your
pistol measuring
secondary effects (the phenomenon).
