Characterized by a bright and versatile design, the Kowa 8x56 BD56-8 XD Prominar Binocular features an advanced optical system with a series of multicoatings to provide clear viewing in a variety of conditions. Dual Prominar XD elements are used to minimize chromatic aberrations for greater color accuracy, and the phase-corrected Schmidt-Pechan roof prism design avails consistent brightness with a sleek form factor. A C3 coating has also been applied to the glass elements to improve contrast and produce consistent and accurate colors. When all combined with the large 56mm diameter objective lenses, this binocular is especially adept when viewing in difficult and low-light conditions.
A rubberized chassis offers durable and secure handling and the housing has also been nitrogen filled for water and fog resistance. Twist-up multi-step eyecups benefit clear viewing in bright lighting conditions and a KR coating has also been applied to the exposed optical surfaces to protect against dust and dirt, and to aid in cleaning.
