Hawke Sport Optics 10x50 Endurance ED Binoculars (

Designed with large objectives - phase-corrected prisms - and extra-low-dispersion glass - the Hawke Sport Optics green 10x50 Endurance ED Binoculars are ideal for low-light situations - such as during predawn 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 binoculars will bring your subject up close for making detailed observationsTo help offset the weight of the over-sized objectives - the Endurance ED binoculars are built with a lightweight polycarbonate chassis that is corrosion resistant to help it hold up to a lifetime of outdoor use It is also temperature resistant - so the optical tubes won't expand and contract with temperature fluctuation - which - over time - can cause the optics to move out of collimation and prevent the binoculars from being able to achieve sharp focus 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 waterproof 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 binoculars to be customized to most people's needs - and the twist-up eyecups means they can be comfortably used with or without eyewear
