Description
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.Optical Performance 10x magnification42mm objective lens diameterPhase-corrected prisms provide improved light reflection, high contrast, and true color fidelitySK-15 prisms have a higher refractive index than BK7 and BAK4, with a lower dispersion than BAK4HOYA extra-low dispersion (ED) lenses virtually eliminate chromatic aberration for true color transmission across the entire field of viewAnti-reflection Advanced MultiGuard fully multi-coated optics improve light transmission for brighter high-contrast images with accurate color renditionWide 65 apparent angle of view340' field of view at 1000 yardsShort 5.9' minimum focus distanceUse and Handling Open-bridge/dual-hinge designLarge knurled center focus wheel is easy to manipulate even when wearing gloves56-74mm interpupillary adjustment range 4 center locking dioptric adjustmentThree-stage click-stop twist-up eyecups for comfortable use with or without eyewearTripod mountable with optional adapterExceptionally long 19mm eye reliefComfortable 4.2mm exit pupilConstruction Details Bridge design reduces weight and provides a more comfortable and secure grip by allowing user's hands to wrap completely around the optical tubesLightweight and durable magnesium-alloy chassisO-ring sealed and nitrogen filled to be waterproof and resistant to internal fogging when moving through extreme temperature changes and environmental conditionsTextured rubberized armor provides a slip-resistant grip in cold and wet weatherFlip-down tethered objective lens covers
