Just like its namesake, Cronus the King of all Mythological Greek Titans, this is the King of the Athlon binoculars! Athlon's Cronus family brings products inspired by a combined commitment to brightness, clarity, resolution, and exceptional ranging capabilities. Designed for serious glassing, with exceptional edge-to-edge clarity, sharp detail enhancement, ultra-clear brightness, and true color representation. With ranging capabilities of 5 yards to 800 yards on a deer and out to 2000 yards on a reflective target, these range-finding Binoculars are perfect for any hunting or long-range situation. We designed these binoculars with our revolutionary E2ES lens system that gives you a flat field of view. Athlon included ED Glass resulting in a clearer and sharper image, as well as an illuminated ranging display.
