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.
thats why I asked. I doubt it, but I don’t know.
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?
