I don't think it would overcome the possible limitations of the digital ones, Greg. I'm really unsure about any of the calliper's accuracy but I've only ever wanted one to get me within a wider tolerance over larger distances.

Moving back to the micrometer which in essence is a pretty simple device, to take an imperial one, it's a 40 tpi thread so one turn is 25 thou. It seems to me, they can mark those graduations reliably and it is a more accurate tool than the caliper.

One advantage with a digital one is regardless of the thread used, you essentially get 2 micrometers in one - for those that want to switch between metric and imperial.
