I quit using a peep when I was 18 years old. I had 2 nice 8 pts. walk onto a food plot 10 yds. away. It was still light enough to see the deer well. when I drew on one of them I couldn't see anything. I had even drilled the peep out A few weeks before in anticipation of this happening. Needles to say I did not take the shot. When I got back I took the peep off. It only took a couple of days practicing until I was shooting just as good, and now can shoot in low light situations. Thats why I no longer use a peep shight.
