Re: Digital Caliper Recommendation

The PFM HO caliper is an all metal conventional Vernier caliper (not a "dial”). It’s of excellent construction and reads in both HO inches and 1/000”. It’s easy to use once you learn how to read a Vernier. It’s a great HO modeling tool.toggle quoted messageShow quoted text
While dial calipers have largely superseded Vernier calipers, being easier to read, they are more delicate and subject to errors from the gear-rack.
Today digital (electronic) calipers are popular and have some advantages. I use them, but it seems that every time I need one the battery is dead or has lost contact. Then it’s grab the dial caliper. Or reach in the toolbox and drag out the trusty old Vernier. There’s just nothing to go wrong with them (short of physical destruction).
