Details
All the binoculars of the Extreme series are massive instruments with uncompromising optical solutions used. The best optical properties supported by solid mechanics were the priority for their design. Hence the porro prism construction and the presence of the low-dispersion optical elements and solid prisms made of high quality BaK-4 glass. Thanks to powerful prisms you do not have to worry about vignetting and darkening of the image at the edge of the field of view. In addition, Extreme binoculars use anti-reflection coatings (FMC), which cover all the optical elements. They provide more than 90 percent light transmission throughout the system. Bodies of all the Extreme binoculars models are made of durable metal and coated with a special rubber veneer. Of course the Extreme binoculars are water-proof. DO Extreme binoculars have individual focusing system.
