This proves the theory of shoot small miss small. The spot is the only thing that you are looking at so naturally you will focus on the spot. You can do the same in the daylight by concentrating on one spot on the animal that you are shooting. I have shot outside in the dark when there was no other way check the sights on my bow when a problem was encountered, and I was heading out the next day. It kept me from shooting down the hallway in the house. ( That went over like a fart in church) It sure does make it easy to pick the spot.
