ED Prime GlassED Prime Extra-Low Dispersion fluorite glass delivers amazing color resolution and contrast, and virtually eliminates chromatic aberration and color-fringing to bring out the most distinct details possible in low-light conditions. Allowing you to see clearer and brighter.
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.
PC-3® Phase CoatingOur exclusive PC3 Phase Coating is applied to the prisms to bring each image into sync after it has been halved and rejoined after being split by a roof prism optical system. It enhances resolution and contrast for the brightest and clearest images possible.
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
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.
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.
ZoomVariable power, or zoom, enables the user to zoom in on an object or zoom out to a wider view through the use of a dial, lever, or setting.
