Yeah, I learned as a youth, if I recall, it like reading a micrometer, correct?As a former Master Mold Maker who sold off a lot of my bigger diameter tools such as calipers and micrometers, that is a fantastic deal on the calipers. The problem today is that a lot of people don't know how to use them if they don't have a dial to read. Explaining to someone who hasn't used anything but dial calipers is tough and getting the proper feel adds more complexity.
