I currently have a digital dial indicator with resolution of .001. I was thinking about going to an analog and a better indicator. Batteries are always dying and analog just seems easier to use. I was looking at the Mitutoyo indicators.

My application will be jointer/shaper tooling setup initially.

I see there are .001 resolution dials that have resets on them so you can zero them out, and there are other dials with resolution of .0002 but don't appear to be resettable. Few questions:

1. It seems like .001 is enough for woodworking? The .0005 or .0002 is attractive but it seems like it might be overkill.
2. How important is the ability to reset? (I'm assuming the .0002 analog etc can't be reset).
3. The ruby tip seems nice, any thoughts?

Anyone have any specific recommendations? I saw several threads that recommended HF.. It seems like a shame to spend $150 on a holder and $20 on the actual indicator, but I don't want to waste money either.
