I have always wondered if the actual distance is different from 20 ft up in the stand to the ground when you are ranging the same object from the same tree? Hope this question isn't too confusing, it is kind of hard to word it the way I mean it. Basically, if a deer is 30 yards from the base of the tree, would it read 30 yds. on the rangefinder if you ranged it from 20 ft. up in the stand?
