Review on Enhance Precision with the David White D620 Sighting Level by Fritz Wiest

This is not a builder level. The purpose is to make rough estimates of altitude. I need to determine the rise and fall of a property to determine building needs before making any offers to buy. He does that very well. You can make a very rough but satisfactory topographical map of the area (without holes and bumps) for preliminary drawings. Eventually, however, I would switch to the builder or transit layer. It really serves the purpose for which it is intended.
