The Ares G2 20-60x85mm Spotting Scope by Athlon Optics was designed to deliver high optical quality in an easy to use package. It features an apochromatic lens system and UHD extra low dispersion glass to deliver an image with next to no chromatic fringe with enhanced contrast, sharpness and color definition. The optical quality is improved even more thanks to its BaK4 prism with an Enhanced Spectral Prism (ESP) dielectric coating. In addition, its variable power eyepiece can be swapped out with a fixed power eyepiece that has a MIL ranging reticle to help determine distances.
