I was wondering if anyone knows of a rangefinder that can calculate the height of an object w/o having a clear line of sight to the base (i.e. no 'three point' method)? It would have to assume level terrain, but for what I need, that would be a fairly accurate assumption.

If you use a *range* finder, than you should know how far away that subject is away from you (in any direction, not necessarily horizontal. If you then also can find out the exact angle your line of vision is referenced to the horizontal, then simple high-school geometry can find the height of the object in question .

Now back to your question if the unit you are looking through can do all the calculations for you .
No idea if there is such a thing ...

You *did* say level terrain !

Yeah, I can do the calcs, but I have a bunch of heights to do in a relatively short period of time. If it included the angle automatically, that would probably work .
