Engineered with over-sized objectives and a large exit pupil to optimize its low-light performance, Hawke Sport Optics' green 8x56 Endurance Binocular sports a fully multi-coated lens system and phase-corrected BAK4 prisms to produce bright and clear high-contrast images from pre-dawn to post-dusk. This 8x optic has the ability to focus in under seven feet, making this Endeavor ready for almost any intermediate to long-range glassing task. The magnification is kept intentionally low to give users an exceptionally large 7mm exit pupil to accommodate user's pupils when they dilate as it gets dark so the view through the optic is easy to see without vignetting.
To help offset the weight of the large objectives, the Endurance 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 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 the twist-up eyecups provide comfortable use with or without eyewear.
