Discovery are lightweight models of binoculars with durable construction. The aluminum, rubberized body hides the lenses built from 8 elements in 12 groups, which are multi-coated with effective anti-reflection layers. Wide eyecups and large eyepiece lenses make any observation a pleasure.
The binoculars are equipped with adjustable eyecups, so we can adjust the distance of the lenses to the structure of our eye sockets.
Delta Optical Discovery binoculars have a variable magnification of 10-22x and a lens diameter of 50mm. The maximum magnification of 22x allows for detailed observations. A Porro prism system was used - in which the objective lenses are not coaxial with the eyepiece lenses.
