I have all different kinds of mics. Vernier, dial, mechanical/digital, and electronic. I think my favorite is my Mitutoyo electronic caliper. It's been amazingly accurate, quick to read, and durable. When I was a mechanic I used to set up a lot of rear differential gears, and they all had shims that had to be measured and stacked to give the correct preload on the bearings. The caliper was a Godsend when you had to measure a dozen shims...especially if you were doing the job on commission (time is money)
Even after I retired I keep my Mitutoyo next to my lathe. The screen is all scratched, but it's still VERY accurate. I also have a complete set of the geared digital readout mics. They are high quality, and have served me well while I was working. Now, the 0" to 1" mic seems to get used the most.
I also have an old dial type caliper that never fails to give unfailing accuracy, for some reason (probably because it cost nearly $200 when I bought it 30 years ago) BTW, I bought the Mitutoyo caliper brand new about the same time, $250 I believe...I recall the other mechanics were astounded that I would spend that much money on a measuring tool..I don't even want to think about how much the set of mechanical/digital mics (in a padded wooden case) cost me...probably somewhere around the price of a weeks' pay, back then...
Try to stay away from the $20 Chinese mic. They're not really that good.
I also have an OLD browne & Sharpe 1" mic...I've kept it all of these years because I was the only one, besides my uncle, who could read it (it's an old vernier scale mic) It was good to scare off tool borrowers looking for a mic...

Far cry from the Ebay Chinese set for $180.00Can. So how bad can the chicom ones be for that kind of difference???

) that changes its reading, when its cold in the shop, and I touch it to any metal chucked up in the lathe. I have gotten to measuring with it, take it off the work, zero it and then close it. Only way I can read it when it is cold. Strange!!!
