I'm a locksmith now and have been told it's a good brand! So I bought this one thinking it would help me get used to using mics and the guy who calibrates our instruments can't match digital! The microphone is calibrated but the numbers are not displayed! Still usable at the moment, but it's not as good as I'd like it to be! Not a real Fowler mic, it's made in China, Fowler is an American company!
