With their ample aperture and excellent optics, the National Geographic 8x40 binoculars are a versatile choice that can satisfy bird watchers, nature lovers and even moon gazers. Made of fully multi-coated BaK-4 glass, the high-end optics deliver images that are rich in contrast and clarity. Their 40mm aperture has the light-gathering capacity to produce bright images even in low-light conditions and the 8x magnification power reveals well-defined details.
The binoculars have a porro prism design with a nice field of view, a centrally located focusing wheel and diopter adjustment capability. They are rubber-coated to protect the optics from small bumps and minimal exposure to water and come with a neck strap for added security when the binoculars are in use. A case and cleaning cloth are included.
