Named after the King of all the Greek Titans, the Cronus G2 10x42 UHD binoculars are designed for heavy duty use in any condition. The Cronus was built with Athlon’s own E2ES lens system which provides a flat field of view with sharp, brilliant images. The image quality is enhanced even further with Athlon’s cutting edge Enhanced Spectral Prism (ESP) dielectric coating, which reflects 99% of the light to the user’s eyes for a bright picture with accurate color reproduction. In addition, the Cronus was designed with a magnesium chassis, which provides the strength of a metal chassis while reducing the weight by 35%.
