I have a Pi Tape brand diameter tape, the kind that starts out 1/2 inch thick but the reading areas are each 1/4" thick and offset from each other to avoid errors.
I recently saw a picture of a diameter tape that functioned more like a belt buckle; the whole tape was about 1/2 inch thick, but the reading area formed a hollow square that you thread the 'tail' of the tape through. It looked like it might be a lot easier to use than the one I already have.
Problem is, I have no idea who made it and I can't find it in the google - which, I'm assuming, is a function of my ineptitude more than anything else.
Anyone seen or possess such a thing? I really need to go buy one. Really, I need it.
