Bresser National Geographic 10×50 are classic Porro prism binoculars with brilliant optical properties. High-performance 50mm lenses made of fully coated BK-7 glass and 10x magnification guarantee a decidedly high light transmission through the glass, thus increasing color fidelity and contrast and giving a stable and clear image even in twilight conditions. Diopter adjustment ranges from -5 to +5 diopters. The distance between the pupils is also adjustable. The sufficiently large body is made of plastic with rubber armoring. A standard tripod thread lets you use this device for stationary observations. These binoculars are perfect for any nature observations: hunting, fishing, and hiking.
