I have the older 10x45s, have no problem reading them, you just have to get eye cups set right for your eye, have had them up to 1723 yds, they easily read the trees or bushes almost a mile from my tree stand. Long ago one night in tree stand just waiting to come down after dark I just started ranging stuff, I was amazed it would do anything up to 1723 yds. Not quite as good as my Vectronics Terrapin , 4945 yds , just kept driving out of town at sun down one night and shooting the water tower until It wouldn't go passed 4945 yds. Wish I could shoot that far.
