Tasco's 8x42 Essentials Binoculars are ideal for finding and tracking 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 pre-dawn 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.
