It does bring up the point that an electronic readout can resolve to higher precision than a mechanical dial readout. Whether or not either display is accurate is a different matter.

I certainly did not intend this thread to be a discussion of measurement accuracy, but perhaps that is good as it helped me to quantify what I am looking for. I think my last post stated it best.

Can you recommend a 100psi gauge that can resolve 1psi, and works with either schrader or presta valves? No need for further discussion on all the nuances of making measurements. No need to suggest I buy a floor pump, I have one with a gauge already. If you wonder why I want a second gauge, don't bother posting, or at least don't be put off when I don't respond to your post.
