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.
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.
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
