I was reading the specs on a DeWalt laser level. It said that it also reported distance. It indicated its accuracy as 1/16 in. per 100 ft, with a range of 2000 ft.
Q: is curvature correction involved? In other words, does it report true elevation difference at distance, or simple rod reading? At 2000 ft curvature is about 0.1??.
I was curious as to how sophisticated a laser level is.?ÿ
I doubt it corrects for curvature, they are normally a transmitter and receiver type setup. ?ÿI wouldn??t push them out to anything near 2000 feet.
Larry could give me the model number of the DeWalt you are looking at. Your question is a very good one and I never thought of?ÿ
it. I would say NO but don't have a clue as to the real answer. If you find out one way or the other please let us know. I will also try
to find out for you.

Pratically speaking:?ÿ don't do that 🙂
Theoretically speaking:?ÿ The principle should be the same as an autolevel - refraction would compensate for some of the curvature.?ÿ?ÿ
of course in principle a laser level is the same as an auto level. The question is what the receiver returns. It states a 2000 foot distance measurement. I couldn’t find technical description beyond “1/16 inch at 100 feet”.
so at 2000 ft what is returned to user? Simple rod reading, or a more sophisticated computed elevation difference?
