The best, realtively inexpensive calipers I have come across are form accu-track.
Digital and use a three site formula. Very accurate repeatability.
For repeatabliity, have the same person use the same calipers at ~ the same time of day. I also use landmarks for consistancy. If there is a freckle/mole etc close to where I'm "supposed" to pich, I will alter the site slightly. That might vary the actual number a bit, but the benefit from repeatability is worthwhile in the long run as you are always tracking a trend anyway.
