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.
Waterproof/FogproofProducts are O-ring sealed and nitrogen purged for total waterproof and fogproof protection. These models can withstand complete immersion in water and stay dry inside. The interior optical surfaces won’t fog due to rapid temperature change or humidity.
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.
