Yes i have had a bit of experience. Once went out with a mate who had a night vision scope fitted to his .243. This bit of kit was the latest thing that they were using in the gulf war and don`t think that he should have had it strictly speaking. Wow, it was unbelievable, we just sat up a tree and kept looking through it for foxes and when we spotted one, called it in without it having a clue. My mate gave the gun to me and gave me the opportunity. I spotted a fox, called it in and shot it without ever having to put a lamp on. He also had a spotting scope. I think he paid about £3000 for this scope so it aint any old night vision that you are going to get from the local gunshop. Not sure how good the ones are that you can pick up from the shops.
