My X-Sight 5-18 using the UNV20IR provided great distance visibility. My longest ranged area was 576 yards and the UNV20 did it's job. I have no doubt I could pick up a pigs body (not just the eye reflections) at that distance. I couldn't make the shot but I'd see then
I saw two raccoon at about 225 yards but it was the tail that distinguished them from a possum.
The UNV20IR is a winner.
