Configured with a reliable magnification and objective lens diameter for general-purpose glassing needs, Tasco's 10x42 Essentials Binoculars are ideal for making detailed observations of distant subjects in the field, on the range, at the stadium, or sightseeing around town. Anti-reflection fully coated optics help to maximize light transmission, color rendition, and contrast. The 42mm objectives push the reach of the binoculars' usability from the predawn hours through to dusk. Complementing the optical performance is a lightweight plastic chassis that is wrapped in a protective rubber armor to provide a slip-resistant grip. A large center wheel helps to bring views into tack-sharp focus, with twist-up rubber eyecups for comfortable use with or without eyeglasses or sunglasses.
