The one I've been using for about a year now is a very cheap dial caliper (harbor frieght cheap). It is my first one. It has worked well, but starting to not return consistently to zero. I tried a buddy's digital one and I got all jacked up with the 5 decimal places of accuracy. Figure a good solid dial caliper will suit me fine for years, and that y'all would have some thoghts. Thank you.
