The National Geographic 8x42 is a roof prism binocular, which features a magnification of 8x and an optical aperture of 42mm. A diopter adjustment allows diopter corrections up to +-2. A high quality full coating on all glass elements reduces distracting reflections, improves the light transmission and provides a high contrast also in bad light conditions.
Furthermore, a special feature is also the stain resistant rubber face, which also provides water resistance. A tripod socket is also included for ease of use with a tripod.
For easy transport of the National Geographic 8x42 binocular we deliver a comfortable shoulder strap and carry case.
