Argon PurgedArgon purging is a more effective purging method than traditional nitrogen. Argon has a higher gravity, delivering a more complete seal. This provides ultimate water-and-fog proofing while helping keep your glass clean and firmly in place. It will withstand complete immersion in water or anything else the harshest environments can throw at it.
Fully-Multi Coated OpticsAll air-to-glass surfaces feature multiple layers of anti-reflective coating. Fully multi-coated optical systems deliver the brightest, highest-contrast images with the least amount of eye strain because only a very small percentage of light is lost before it reaches the viewer's eye.
Ultra Wide Band CoatingAn anti-reflection coating process that is customized for every lens element in the optical path, in order to allow the best possible light from the front glass all the way back to the eyepiece. The result? Optimum brightness and true color across the light spectrum.
RainGuard HDThis patented, permanent, water-repellent coating causes moisture from rain, snow, sleet and condensation to bead up and scatter less light, so you get a clear, bright view when other optics would be rendered useless
RevLimiter Zero StopOnce a zero has been established, the elevation knob can be precisely returned to zero after "dialing up" by setting the RevLimiter Zero Stop mechanism.
Side Parallax AdjustmentEver notice that your crosshairs appear to move around to different points on your target? This is called “parallax error” (target and reticle are not in the same focal plane). Side Parrallax adjustment allows for parallax compensation by moving an optical element until the target (based on its distance) appears in the same plane of focus as the reticle.
