The 7x33 Granite Binocular from Celestron is a weather-sealed optic designed for close to mid-range observations. This lightweight binocular weighs less than 2 lbs and is compact enough to fit in the side pocket of a daypack. In addition to the Granite series' streamlined form factor, this fixed-magnification binocular features extra-low dispersion (ED) objective lenses and phase-corrected BaK-4 prisms that render enhanced brightness, clarity, and color fidelity. Complementing the fully multicoated lens system, an immersive 64° apparent viewing angle, impressive 6.5 ft minimum focus distance, and balanced open bridge body design help provide a user-friendly glassing experience that is ideal for birding. The Granite binocular has a nitrogen-filled magnesium alloy housing that is built to withstand heavy rain and deliver fogproof performance, making this Celestron optic ready to handle almost any outdoor glassing activity.
