Antireflection Coated Optics Improve Light Transmission, Color Reproduction and Contrast
Ultra-wide 68.5° field of view keeps the entire playing field in view so you don't have to move your head around to capture the action
900 feet wide field of view at 1000 yards
Use and Handling
Unfocused PermaFocus System

6mm wide exit pupil will cover the pupil, keeping the entire scene in view without moving the eye
PermaFocus System
