DESCRIPTION
The 10x42 BD42-10XD 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 multi-coated 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 to be waterproof, and resistant to internal fogging when moving through extreme temperature changes or environmental conditions. Its center focus wheel is textured for easy handling in cold and wet conditions, even while wearing gloves.
