Designed with large objectives, phase-corrected prisms, and extra low-dispersion glass, the Hawke Sports Optics' black 10x50 Endurance ED Binocular is an optic that is ideal for low-light situations such as during pre-dawn and post-dusk periods. The combination of glass and coatings combined with anti-reflection fully multi-coated optics produces bright and clear high-contrast images with accurate color rendition and virtually no fringing. Whether hunting, birding, boating or watching sporting events, the Endurance ED will bring your subject up close for making detailed observations.
To help offset the weight of the over-sized objectives, the Endurance ED is built with a lightweight magnesium-alloy chassis that is also corrosion-resistant to help it hold up to a lifetime of outdoor use. The chassis is protected by a texturized rubber armor that has an additional pebble-texture placed where the palms will naturally fall to give it a non-slip grip especially in cold and wet conditions. The optical tubes are nitrogen-filled and O-ring sealed to be water and fogproof - especially in extreme weather conditions. To reduce user-fatigue and keep them steady, a tripod adapter mount is located in the front of the hinge for setting them up on a support system. A right-eye diopter adjustment allows the binocular to be customized to most people's needs, and its twist-up eyecups means it can be comfortably used with or without eye wear.
