I used it in a field in bright sunshine. I have targets at 400, 600, 800, 1000 yards. Each steel target measures 2 feet by 3 feet. if it was accurate to 600 yards alone. However, he could not reach the target at 800 or 1000 yards. the product description says up to 1200. - no idea if anyone has the same problem or not. The lens is sharp and clear so I could see the target but couldn't get distance readings for targets at 800 and 1000 yards so I'm giving it a 1 star rating.
