This is fun. So someone tell me if I’m thinking about this correctly as I barely made it through arithmetic classes.

Assume hunting on flat ground in below example:

1) the distance in yards from the base of tree I’m climbing to the target is exactly 25 yards measured with a standard rangefinder.

2) after climbing 20’ high into same tree, using an angle compensation range finder, the finder says shoot as if the target is at exactly 25 yards, EVEN THOUGH the total distance to the target is now something like 28/30/32 yards?

Is that essentially what the angle compensation range finders are telling you to do?
