With a reverse Porro prism design and fully multi-coated lenses for a bright, sharp image, the 10x26 Vanquish Binocular from Vortex is a compact and versatile optic suited to general use. The Vanquish can focus on objects as close as 7.6 feet for viewing butterflies or wildflowers, while its 10x magnification can bring distant details into view. It has twist-up eyecups to accommodate eyeglasses and a knurled, easy-to-operate center-focus wheel. A diopter adjustment is provided on the right eyepiece to resolve differences in the user's eyes. O-ring sealed and nitrogen purged, this binocular is water, dust, and fogproof, and its rubber armoring protects the housing and provides a pleasant and secure grip.
