#58-6800-4 search "digital caliper" from main page and it will link you. My local store was sold out today.
I keep that pair at my work, they are good. I use this pair from Lee Valley at home that measure in decimal & fractional inches as well as millimeters.

just got my pair from Cambodian Tire, looks like they also hve the option to read in inches and MM as well as 0.5 of a fraction of and inch , you can see a small .5 on the right side indicating it.
so far im happy with it
