I have the ats 65 mm with the 20x50 eyepiece and was watching a bull over a mile away. I could tell it was a decent bull. The guide had the swaro 85 mm. Through that the bull turned into a decent 6x6 and it looked like a broken 3rd on the right side.
I used mine for the first time this weekend and was impressed. It was really nice to be able to pass the binoculars to my boys without having to get up and move like if we were using a tripod. It supported my 15x56 just fine and was so compact to carry.
