Product Description

The 8x42 BD42-8XD 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.
