    This video might be of interest to some. It would have been nice (as in relevant) if he had stated what the price differences are. I know but not sure if all do.

    What I find interesting is the way he holds the calipers and measures with them.

    This guy is certainly an exert on precision measurement.

    Def of "expert": A drip under pressure.

    When I started to watch the video I had no idea where the guy was going to take as long as he did. Good quality calipers are better than cheap ones. Who'd have guessed?

    I don't regard the guy as an expert but what he did and how he did it looked OK for a guy in the environment he was in.
    As said, if he mentioned the price for a Mitutoyo it would have helped as he didn't really IMO ridicule the cheap ones. Just showed they weren't as good.

    To me it just looked as if he took better care of some tools more than others.

    When trying to use my calipers to read as accurately as they can (oxymoron aside) I only hold the caliper by the jaws (Part, jaw, finger). I don't use my thumb to move the slider.

    Using this method there's no way to bend the bar of the caliper within reason.

    Flat surfaces, cylindrical surfaces, and spherical surfaces will all have a different feel. It also varies with the diameter of the part. Ideally one would use a standard that matches the shape of the work. Look up Hertzian stress

    I just squeeze until I get the right number...if I can't squeeze enough I'll usually take the part to the belt sander.
