Discovery are light models of binoculars with a durable construction. The aluminum, rubberized body covers lenses built of 8 elements in 12 groups, which are repeatedly coated with effective anti-glare layers. Wide eyecups and large eyeglass lenses make observation a pleasure.
Discovery 10x50. Its universal features (10x magnification and 50mm lens) allow for convenient observation both day and night. This pair of binoculars is a compromise between getting a high magnification and a wide field of view. At the same time, it provides a large surface brightness. It is a good proposition for those who, in addition to daytime observation, would like to admire the night sky. • Lens diameter: 50 mm
