Multi-coated optics give you better than 95% light transmission with virtually no distortion.
As a result, the image is not only brighter, it's as sharp at the edges as it is in the center.
Internal chambers are sealed and dry nitrogen filled, forever preventing any internal condensation, or fogging due to mold growth.
Other features include extra long eye relief for eyeglass wearers, fold back rubber eyecups, dry nitrogen filled, and a non-slip rubber coating.
