The 20x80 X-Trail Binocular from Barska has large objective lenses to maximize light transmission and a generous magnification to bring the viewing target right up-front. The green tinted lenses reduce glare in bright sunlight environments. The X-Trail's traditional Porro design with superior BAK4 glass and multi-coated optics create a viewing experience of clarity and highly contrasted images. Rubber armoring with indented finger holds provide a protective non-slip grip and added protection for the housing and internal optics. The extended size of the 30x80 X-Trail is reinforced for strength and durability with an integrated tripod adaptor brace. All this, coupled with a wide-angle field of view, produces an ideal outdoor binocular for spectacular scenic viewing.
