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. We included ED Glass resulting in a clearer and sharper image- as well as an illuminated ranging display.
