It used to be that calipers were not a common item to have in an electronics lab. However, smaller parts, the widespread use of 3D printers and machining tools, and — frankly — cheap im…
Depends on where you buy them. There are a lot of fake Mitutoyo calipers on e. g. eBay, and not everyone might be aware of that.
And let’s face it, 5 tenths is way beyond what people need at home, 95% of people don’t have any equipment that would even allow them to control any process to that degree of accuracy.
Also, shout out for Shars as another budget option.

.0005" is best case, with the best calipers. If you have spectacularly shitty ones, your accuracy might be more like +/- .005", or ten thou.
I use calipers for reloading; rifle cases need to be trimmed because brass flows under pressure, and you def. have a minimum and a maximum tolerance.
Plus handling errors, of course.
But yeah, a $170 Mitutoyo caliper will also not display anything beyond five tenths, so that’s definitely a hard limit.
