The black rubberised scopes for observation in poor light conditions. The Leader R optics design can even utilise residual light, therefore it is possible to use them at twilight and during a bright night.
They can be used wherever the observer requires high luminosity of the image and large magnification. They are suitable for hunting, tourism, but also for night sky observation. The precise, fully smoothly moving mechanics of the scope allows to focus also in gloves.
All-glass optics with the prism manufactured from special Bak4 optical glass with higher transparency. Nine lenses in six groups are made from K4 optical glass and are provided with 24-fold antireflex layers SMC. The strengthened metal structure of the body of binoculars and its rubber lining allow its use even under the most extreme conditions, as regards either the light intensity or the weather. The body of binoculars is filled with dry nitrogen which prevents their fogging at sudden temperature variation
The scope body is fitted with hardened rubber with increased durability against abrasion and colour change.
