The “Made in Russia” Optics

These binoculars feature Russian optical glass made at the well-known Russian Kazan Optical-Mechanical Plant. Due to high quality standards, Russian optical glass has been recognized worldwide among the military and hunters. The binoculars were designed according to a joint project by the Levenhuk Company and the Russian Kazan Optical-Mechanical Plant. This plant was established in 1940 and has been providing optical observation instruments for over 70 years, first for the Soviet Army and later for the Russian Army.

Metal body

A rugged metal body protects the lenses and prisms from vibrations and accidental hits. It is made of aluminum alloy and all the joints are sealed with a special substance that protects the optical tool from dust and moisture. The optical and mechanical parts of these binoculars are impervious to extreme temperatures. The operating temperature range is from –40 to +50 °C. There is hardly any analog that can surpass the Russian optics and survive such temperature changes.

Additional features

You can easily adjust the binoculars to your needs. They feature diopter adjustment in the right eyepiece, interpupillary distance, and sharpness adjustment. The kit includes a protective case and a neck strap.
