now here is a tool you might take for granted, but it tends to be in near constant use!, a quick verification on size of a component can do wonders for your sanity, at times.

ID suggest most mechanics could use a 6-8" version and a 12" version, the cheaper digital versions are reasonably accurate from what Ive seen testing them against my more expensive versions but keep in mind your mikes are for, fine, measurements are taken with your micrometers, or the best quality dial calipers, the cheaper versions are less accurate generally

not the caliper, that's usually used to get a real good idea of the ball park measurements when you don,t really need precise , measurements, (altho there are exceptionally accurate dial calipers available)
like when your measuring brake rotors where a .001 difference means next to zip!

I think I'd prefer an analog system, yeah they dial might get a little out, but its better than the top of a 7 disappearing.
