Unit performed flawlessly!!! 100% function with included up-graded Mec-Gar mag, although a standard current Mec-Gar would most likely perform the same when new... Anyway, next stop UPS and on the way to Joe! Next post on this thread will hopefully be from Joe with an accuracy range test... As I can't see good enough to make that happen with any degree of success????... Best to all, til....lat'r....GT
