maybe I don't understand this these arc rangefinders. Don't they compensate for the difference in gavitational pull at different angles? Any rangefinder will tell you how far away an object is. Your arrow will drop less the steeper downhill you shoot causing you to hit high.
I believe gravity has exactly the same effect regardless of angle. It is only the horizontal distance gravity "sees".
Regardless of the above statement, I also believe bowhunters do not need angle compensating rangefinders.
