Professional HD Optical System with ED Glass Experience exceptional clarity and detail with fully multi-coated HD lenses and BaK-4 prisms that deliver 91% light transmission for bright, high-contrast views. The Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, ensuring edge-to-edge sharpness and accurate color reproduction during dawn, dusk, and in challenging light conditions for hunting, birding, and wildlife observation. Rugged IPX7 Waterproof & Fogproof Construction Built to withstand the toughest outdoor environments, the magnesium alloy chassis is protected by shock-absorbing rubber armor. Argon purging guarantees fogproof performance across extreme temperatures (-25°C to +60°C), while the IPX7 waterproof rating means it can withstand immersion in 1 meter of water, making it ideal for rain, marine use, and alpine expeditions. Ergonomic Design for Extended Comfort Designed for all-day use, these binoculars feature a lightweight 21oz compact body, twist-up eyecups with intermediate stops, and a long 14.1mm eye relief that comfortably accommodates eyeglass wearers. The wide 5.9° field of view (309ft/1000yds) and smooth focus wheel reduce eye strain and allow for rapid subject acquisition from 6.6ft to infinity. Versatile for Hunting, Birding & Tactical Use A vital tool for hunters to spot game in dense brush, for birdwatchers to identify detailed plumage, and for tactical professionals in surveillance and search & rescue operations. The durable, corrosion-resistant construction also performs reliably in maritime environments, providing critical visual intelligence wherever your adventures take you. Premium Bundle with Lifetime Warranty Your investment is protected by Athlon's unlimited VIP Lifetime Warranty. The package includes high-end accessories: a Harley Davidson-spec neck strap, protective rain guard, objective lens covers, and a semi-rigid carrying case for ultimate convenience and security during transport and storage.
