I read in sci.electronics.design that Spehro Pefhany

question', on Sat, 9 Apr 2005:

You can get low-end LCD calipers in the US for the equivalent of about
GPB8 plus tax. For GPB1 ($1.99) I think you'd get some stamped or
plastic item that would only be good to 0.01".

No, they are metal, and claim to measure to 0.001 inch, 0.02 mm. I've
checked mine against a good micrometer and it's as accurate as I can
read the vernier. YCCMV, of course.
