The Kowa waterproof roof prism binoculars are strong because of their optical performance and nice design. The rubber armoured body is slim but sturdy and has a nice grip. Due to its pop-up oculars they are very suitable for both people who wear glasses and people who don't. The clarity and brilliance give these binoculars the predicate "ideal nature binoculars". These Kowa binoculars are equipped with Schmidt / Pechan prisms with a partial phase coating and on the other side the C3 coating. This exclusive coating has a very high reflectivity and guarantees a translucence of over 99%.
