My dad just got some a few weeks ago. Tested them out this weekend in a pitch black area and was very impressed. Was driving around and saw a doe at about 250 yards.l and was able to see her clearly. Came back to the same area later and was about 350 yards away from the same doe. At that distance she was pretty blurry but I cold still see the reflection of her eyes. Need to remind myself to get some video at those distances.
