I was on a website poking around a little and the new rangefinders with "Arc" or something similar really caught my eye and got me worried about my "standard" rangefinder for bowhunting. I originally purchased a Leica rangefinder for rifle and was not really concerned about having an angle compensating device, but looking at how much it varies based on advertisements it has got me worried. If you are not good at figuring yardage do you consider this feature critical when high stand hunting, or is there a trick? A second and maybe more important question might be at how high a person might be off the ground when this feature becomes more important.
