Truth - accuracy is not precision
A laser is no more accurate than a tape measure.
A laser is more precise than a tape measure.
A wheel is less accurate but just as meaningful unless you have to report in tenths of a foot...it's accuracy is probably under 1% in tenths per 100' unless the ground is really rough and it is that roughness that creates the lack of accuracy. Precision? It will readily measure to the tenth of an foot. It just needs a very smooth surface to roll on. The wheels are normally calibrated to be very precise.
