I used flip up covers once on a elk hunt. I was very close to two big bulls that were bedded. I was afraid to let the flip covers flip up because of the noise they make. While I tried to open both covers quietly, the elk detected our presence and silently disappeared in the timber. I got a small 5 X 5 during a windy, light snow storm without any scope caps. The guide kept asking if I wanted to stop hunting because of the weather. Definitely not after blowing a chance at a big bull because of those dxxx scope caps.
PS: I now keep a lens pen (or two) in my pocket when hunting with a scoped firearm.
