The Steiner 20x80 Military is their largest, highest-magnification configuration of their very bright porro prism collection. This large optic is meant for use exclusively upon a tripod, monopod, or other support, and while its performance in any light is great, it is in twilight that the 20x80 Military's especially stunning. The 20x80 design is a perfect choice for surveillance, but also is practical for use by hunters and astronomers as a substitute for a spotting scope.
The 20x80 Military has Steiner's revolutionary "Sports Auto Focus" system that gives expansive depth of field from 60 yards to infinity once set to the user's individual eyesight. It has tough rubber armor for both great protection and tactile feel, and includes standard peel-back rubber eyecups.
