With a reverse Porro prism design and fully multi-coated lenses for a bright, sharp image, the Vanquish 10x26 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 waterproof, fogproof, and dustproof, and its rubber armoring protects the housing and provides a pleasant and secure grip.
