The Kowa BD56-8 XD Prominar is a large-objective 8x56 roof prism binocular built for low-light viewing. Its 56 mm XD (extra-low dispersion) objectives gather plenty of light and keep colour fringing in check for bright, sharp images.
The prisms are phase-corrected and the optics fully multi-coated, while a nitrogen-filled, rubber-armoured body keeps it water and fog proof. It has centre focus, twist-up eyecups and long 23 mm eye relief, focuses down to 3 m and weighs 1050 g.
