Kowa 10x42 XD Binocular Product Info The 10x42 BDXD PROMINAR Binocular from Kowa combines precision glass and prisms, with optical and prism coatings to produce a binocular that performs well in all light conditions with true color representation. Extra-low dispersion XD glass elements reduce chromatic aberration and image distortion at the edges of the field of view. The lenses are fully multicoated with anti-reflective coatings to maximize the amount of light coming into the optical tubes. The roof prisms are phase-corrected to increase the resolution and contrast, while the C3 coatings reflect more that 99% of the light moving through them. This combination of glass, prisms, and coatings produce high-contrast images that are bright and crisp, with true-color transmission. The magnesium-alloy housing is light and durable, and the rubber armoring on the exterior provides a sure grip and protection from impacts. The optical tubes are nitrogen-filled and o-ring sealed for water and fogproof performance in all weather. Its center focus wheel is textured for easy handling in cold and wet conditions, even while wearing gloves.

Bushnell Trophy Xtreme Green 10x50 Binocular Product Info Designed with large objectives and a wide exit pupil, Bushnell's green 10x50 Trophy Xtreme Binocularis an optic with enhanced low-light capabilities versus optics with smaller objectives. To further boost its low-light abilities are phase-corrected BAK4 roof prisms and anti-reflection fully multi-coated optics that produce bright and clear high-contrast images with accurate color rendition from dawn to dusk. The combination of optics and objectives make the Trophy Xtreme ideally suited for most outdoor activities from hunting, to birding, to sporting events. The chassis is protected by rubberized armor that is textured 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. 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.
