The Vanguard 10x42 Spirit XF Binocular, in black, is designed for avid outdoor enthusiasts and hunters who require an optic that can perform in the harshest conditions and survive a life on the trail. Its 10x magnification enables detailed observations from long distances, while the 42mm objectives draw in copious amounts of light for use in low-light conditions without being overly bulky or heavy like larger-objective binoculars. Complementing the power and objectives are phase-corrected BAK4 roof prisms and emerald-green fully multi-coated optics that improve light transmission, color rendition, and contrast. All these features, when combined with a wide field of view, provide an immersive observational experience with high-contrast images and accurate color representation.To stand up to the rigors of the trail, the chassis is made of a lightweight and impact-resistant magnesium alloy wrapped in black rubber armoring that not only protects the optics from drops and impacts, but provides a slip-resistant grip. An open-bridge/dual-hinge configuration helps to reduce weight without sacrificing strength while increasing the gripping surface for improved stability and comfort. The optical tubes are nitrogen filled and O-ring sealed to make them fog and waterproof in even the harshest conditions. Twist-up eyecups enable easy use with or without eyewear and are made to stay in place without shifting during a climb to the blind, and the binocular is tripod mountable with an optional adapter to reduce fatigue during a long day of glassing.Optical Performance10x magnification helps hunters pick out details at long range42mm objective lenses boost low-light performance without being overly bulkyCompact BAK4 roof prismsEmerald-green anti-reflection fully multi-coated optics improve light transmission, overall image brightness, color rendition, and contrastProprietary P2 phase-correcting prism coatings limit internal light loss and improve contrast and colorWide 63° apparent angle of view331' field of view at 100 yardsComfortable 4.2mm exit pupilLong 16mm eye reliefUse and HandlingOpen-bridge/dual-hinge configurationLarge center focusing knob is easy to manipulate even in cold or wet conditions, or while wearing gloves±4 right-eye dioptric correction helps to correct for prescriptions to use optic without eyewearThree-position twist-up locking eyecups for use with sunglasses or goggles, or withoutTripod mountable with optional adapterConstruction DetailsBridge design reduces weight without sacrificing strength, while providing additional surface area for hand gripLightweight and impact-resistant magnesium-alloy housingNitrogen filled and O-ring sealed for fog and waterproof performance in extreme weather conditionsProtective black rubber armoring with textured palm pads provide a slip-resistant gripIncludes two objective lens caps and a one-piece ocular rainguardWeight: 22.9 ounces
