Hawke Sport Optics 36221 overview

  • 1Description

Engineered to optimize its low-light performance, Hawke Sport Optics' green 10x56 Endurance Binocular features a high magnification and large objectives that produce a 5.6mm exit pupil that completely covers most users' pupils when they fully dilate as conditions darken. To help reduce the appearance of visible hand-shake common with high-power optics, they are outfitted with a wide viewing angle. They sport a fully multi-coated lens system and phase-corrected BAK4 prisms to produce bright and clear, high-contrast images from dawn to dusk, and under heavy cloud cover or dense canopies. With the ability to achieve focus within seven feet using a fast focus mechanism, the Endurance is ready for almost any intermediate to long-range glassing task.

Aptly named, it is built to endure a life lived outdoors in harsh conditions. To help offset the weight of the large objects, the Endurance sports a lightweight and corrosion-resistant aluminum alloy chassis. The optical tubes are nitrogen-filled and O-ring sealed to be water and fogproof - especially when moving through extreme temperature changes. To reduce user-fatigue and keep them steady, they are tripod mountable with an optional adapter, available separately. A right-eye diopter adjustment allows the binocular to be customized to most people's prescription needs, and the twist-up eyecups provide comfortable use with or without eyewear.
