Kowa BD III 10x42 XD Binoculars (Kowa, SKU: 138462 / 12802) are wide-angle roof prism binoculars designed for observing nature, birds, wildlife, landscapes, and other distant objects. The 10× magnification is combined with 42 mm objective lenses, a wide 7.2° field of view, and Kowa XD lenses made from extra-low dispersion ED glass, reducing chromatic aberration and helping preserve natural color reproduction. The lightweight magnesium alloy body, waterproof nitrogen-filled construction, and protective KR coating prepare the binoculars for regular use in the field.
