Vanguard - 10x42 Endeavor ED IV Binoculars

The B&H Binocular Buying Guide

Building on the success of their earlier iterations, the Vanguard Optics 10x42 Endeavor ED IV Binoculars get 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, combined with an exceptional 65° wide apparent angle of view, work together to reduce the appearance of visible hand shake common in high-power binoculars to present 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 binoculars boast 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. Engineered for durability, the lightweight magnesium-alloy housing is O-ring sealed and nitrogen filled to be waterproof and resistant to internal fogging when moving through extreme temperature changes and environmental conditions. The Endeavor ED IV provides the performance and comfort birders, hunters, and outdoor enthusiasts require for long observation sessions in all weather.
