what about those pinpoint cal monitor...worth the money? trying to simplify things here

so did you every try it or no...I was reading about the pinpoint one and it stated that it could be run constantly with the adaptor (so it wouldn't be run on just batt)...I don't see how it would have to be calib every time if that were true...not meaning to be scarcastic
