I was sitting around today trying to figure out if you need to aim any differently when hunting out of a tree stand. I was thinking, the distance from you in a treestand to the deer will be greater then that of the horizontal distance. Then, you are elevated and the arrow is traveling down, and for some reason I want to say it will fly high. Lets say you are in a tree stand the you have rangefinders with you. The deer is 20 yards from your position. Do you simply put the 20 yard pin on the deer and let the arrow fly, or do you aim for about an 18 yard shot, or low with the 20 yard pin?

Thanks for the help.
