Query: accumeasure 2000 body fat caliper.

Not impressed with the item at all. It would have been better if the readout of the measurement locked into place on the scale, so that I could get an accurate reading, and then release it afterwards. The way it currently works is that it releases from the scale when I try to read it after a measurement, due to the change of my hand grip pressure. I would need a second person to read it in place, to get an accurate reading without taking my hand off of the caliper.
