Mechanical dial calipers calipers are such a technical improvement over archaic vernier calipers that they're comparable to when humans switched from stone to metal tools!
I gave up on trying to accurately guess readings with vernier calipers 35 years ago! I bought a set of dial calipers as soon as I could afford them so I guess that makes them on topic...
These days, you can get a pair of digital calipers much cheaper than most mechanical dial calipers.
Accuracy is in the eye of the beholder! ;-)
