Building on the success of their earlier iterations, the Vanguard Optics 8x42 Endeavor ED IV Binocular gets upgraded with HOYA extra-low dispersion (ED) glass, phase-corrected SK-15 roof prisms, and their advanced MultiGuard optical coatings to improve light transmission, color rendition, clarity, and contrast; while eliminating chromatic aberration. These updated technologies and materials work together to produce an immersive observational experience on the trail, at the range, in the stadium, or sightseeing around town. To pick out feather and fauna details, the binocular boasts an impressive 5.9' close focus distance.
An open-bridge/dual-hinge design helps to reduce weight without sacrificing strength, and provides a large surface area to improve grip strength and security. Textured rubber armoring offers protection from drops and impacts, while further improving the grip and comfort in the hand. Designed for durability, the lightweight magnesium-alloy housing is nitrogen-filled and O-ring sealed to be waterproof, and resistant to internal fogging when moving through extreme temperature changes and environmental conditions. The Endeavor ED IV's provide the performance and comfort birders, hunters, and outdoor enthusiasts require for long observation sessions in all weather.
