NATIONAL GEOGRAPHIC 8X42 Roof Prism Binocular

The NATIONAL GEOGRAPHIC 8x42 is a roof prism binocular with 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 reduce distracting reflections and improves the light transmission and provides a high contrast particularly in bad light conditions. The binocular is built with a handy and stain resistant rubber surface. A normal tripod connection allows to fix it on a tripod for better observations. For better transport a bag and a comfort strap is included in the delivery.
