The Vanguard 10×42 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.
