Just like its namesake, Cronus the King of all the Mythological Greek Titans, this is the King of the Athlon Optic binocular kingdom Athlon brings to you the Cronus family, 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 colour 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 long-range situations. We designed these binoculars with our revolutionary E2ES lens system that gives you a flat field of view. We included ED Glass which results in a clearer and sharper image to your eyes as well as an illuminated ranging display.Features:- E2ES System- Edge 2 Edge Sharpness system: E2ES System is a field flattening system that produces sharper, clearer images all the way from one lens edge to the other- ED Glass- High-definition glass: ED glass gives you an image with little or no chromatic fringe, so the final result brings an ultimate clearest and sharpest image to your eyes- ESP Dielectric Coating- Enhanced Spectral Prism Dielectric Coating: ESP Dielectric Coating is a multi-layer prism coating that reflects over 99% of the light to your eyes bringing you a clear, bright image that displays accurate colour reproduction.- Lightweight Magnesium Chassis: Magnesium chassis gives you the strength of a metal chassis while reducing the weight by as much as 35%- XPL Coating- Xtra Protective Layer coating: XPL Coating gives you extra protection on the exterior lenses from dirt, oil, and scratches- Phase Corrected prisms: Phase-corrected prisms produce images that have better contrast, a higher resolution, and better colour reproduction- Bak-4 prisms: Bake-4 glass prisms reflect more light to your eyes which will give you a brighter and sharper image.- Advanced FMC: Advanced Fully Multi-Coated lenses gives you better light transmission to bring optimum brightness and true colour across the entire light spectrum.- Long Eye Relief: Long eye relief can be particularly important for eyeglass wearers because longer eye relief allows them to still see the entire field of view.- Close Focus: Close focus is important for those who are nature observers and especially important if you are going to watch butterflies or insects- Twist Up Eyecups: Twist-up eyecups with intermediate stops allow you to set the eyecups to the ideal eye relief for your eyes- Waterproof: Waterproof to protect the binoculars in the harshest weather conditions or if accidentally submerged underwater- Argon Purged: Argon purging gives you better waterproofing and thermal stabilitySpecifications:- Range Reflective: 1828.8m- Range Deer: 731.52m- Accuracy: +/-0.5Y- Max Angel Reading: +/-70 Degrees- Power: 10X- Objective Lens Diameter: 50mm- Eye Relief: 19.3mm- Field of View Angular: 6.5 degrees- Field of View M @1000 METERS: 113m- Interpupillary Distance: 5.6mm-7.3mm- Weight: 1077.28g
