Characterized by a bright and versatile design, the Kowa 10x56 BD56-10 XD Prominar Binoculars feature 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. The 10x magnification is ideal for viewing distant subjects and when all combined with the large 56mm diameter objective lenses, these binoculars are especially adept when viewing in difficult and low-light conditions.
