The Ares G2 15-45x65 Straight Angle Spotting Scope was designed for two proposes: advanced optical quality and ease of use. 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.
