Designed for those in need of optics that can keep up with their adventures, while not breaking the bank, and with extraordinary edge to edge clarity, sharp fine-detail enhancement, ultra-clear brightness and true color transmission, the Athlon Cronus 10x42 binoculars are rugged and built to last while still not emptying your wallet. Whether you are on your yearly hunt for coyotes on the family farm in the midwest or filling your tag on a majestic Rocky Mountain elk, don't settle for anything sub-par. Athlon designed these binoculars with their revolutionary new E2ES lens system, which gives you a flatter field of view. They included ED Glass that provides perfect clear and sharp images. The state of the art ESP (Enhance Spectral Prism) dielectric coating reflects 99% of the light through the prism assembly, for superior light transmission. The Cronus has a magnesium chassis to reduce weight while keeping the optics rugged enough to withstand the use and abuse of even the most fearless adventurer.
