The Steiner 10×50 Nighthunter XP is a tried-and-true high-magnification configuration of their very best and brightest porro prism collection. The Nighthunter XP provides the highest light transmission across the entire visible spectrum of any porro prism unit in the world, and you can truly see the difference when light is poor. While its performance in any light is great, it is in twilight that the Nighthunter XP is especially stunning.
The 10×50 Nighthunter XP has Steiner’s revolutionary “Sports Auto Focus” system that gives expansive depth of field from 60′ (18.3 m) to infinity once set to the user’s individual eyesight. Eye relief is 21mm, comfortable for most users even when wearing eyeglasses, and an external “Nano” coating helps shed water, dust, and debris from the eyepieces and objectives. It has tough rubber armor for both great protection and tactile feel, and includes 3 kinds of eyecups to give an ideal view for any user in any light.
