 So if you are looking at that deer that's 600 yards out, and it range finds on it, and it calculates with the temperature and density altitude and the inclinometer, your incline angle up or down of your firearm, and it lights up a light, and that's the light that you put as if it were the crosshairs right on the sweet spot on the deer. Well, this would do that for a 20-foot tall deer.
