Designed for terrestrial or celestial observations, the Barska 20x80 X-Trail Binoculars feature large, oversized objectives and green-tinted multi-coated optics that reduce glare while boosting light transmission to produce bright and clear high-contrast views with accurate color rendition. The traditional Porro design with BAK4 glass, coupled with an exceptionally wide angle of view further improves the observational experience by providing near panoramic views with rich depths of field. Rubber armoring with indented finger holds provide a protective nonslip grip and added protection. The large objectives and long optical tubes of these binoculars are reinforced for strength and durability, with an integrated center brace-bar that sports a tripod adapter to make mounting them on a support system easy. Whether you're looking at expansive vistas or hunting for comets, the X-Trail binoculars are sure to become your constant outdoor companion.
