Outstanding Calipers
These calipers are the most accurate set I have ever used. The read out is clear and easy to read. The construction of the unit is very well made. I would buy these again and again. If you are in need of a very well made set of this type of caliper, these are the ones to purchase. Don't bother with a cheaper made brand.

Tired of squinting!
Taber N on Jul 2, 2020
I have an old one that a dial gauge, so pretty hard to see now that I am getting older. I hope that this digital gauge makes it easier on the eyes.
