Got to agree with Mr.Joe, the Emerald is just about everything a fella could ask for in the $400 price range. I had to send my first one back in to AoA because of fogginess in the rube ,,, AoA was great about a replacement and have never looked back. Tracking is exceptional, tons of aim points, lock down turrets, great glass clarity ... I like it better than my Sidewinder 8-32x56. Have had it for 6 months now and it's a keeper.
