Does anyone know more detail on the accuracy of the laser distance measuring
devices? E.g. something like this:

It says the accuracy is ± ¼" at 100 feet. Does that scale proportionally, so
that at 50 feet, the accuracy is 1/8", and at 25 feet, the accuracy is
1/16"? Or is the accuracy going to be 1/4" independent of the actual
distance being measured?

Furthermore, is the error a consistent error, or random error? In other
words, if I use it to measure a 100 feet distance 10 times, would I get 10
different readings distributed in a 1/4" range, or would I get the same
reading 10 times that is within 1/4" of 100 feet?
