Sam -
PS: I've had to use calipers for the good part of 20+ years now..
Dial calipers were nice, but, IMO don't hold a candle to digital.
Especially in My case - being far sighted, and not wearing glasses..
A quick glance beats squinting / concentrating longer every time.
Now, as mentioned before a few times..
Anyone who needs a basic set of calipers really doesn't have to go crazy,
or look any farther than a Harbor Freight store.. Those will do just fine..
I've used a few pair over the years in my fab shops, and never an issue..
I even had a friend send me a set from NewZeland years ago
that were no doubt 'Chinesium' in construction and of HF quality, and...
I still use those things - if/when I can find them.
When I closed my shops, I sold off all of my expensive gear
calipers included. When I needed another setup - Yup - Harbor Freight,
and the newest set also works perfectly.
If 'absolute precision' is needed for machining/tooling/etc.
I'd recommend going with a higher quality set..
The boards, electronics / components, construction is better,
and the slides will no doubt track much smoother.
Anyway . . . Carry on.
