I think John in Edmonton has said he can hear the difference between a pull tab and a gold ring. I just tested about 15 rings and 5 or 6 different pull tabs (air test) and I can't tell the difference. The only thing I noticed is I got much stronger signals from the rings at 4 inches and broken signals from most of the pulltabs at 4 inches. I have found my share of rings and I never said, that's a ring, before I started digging.
Any help always appreciated.
