Vortex Vanquish 10x26 Binoculars

The Vanquish can focus on objects as close as 7.6 feet for viewing butterflies or wildflowers, while their 10x magnification can bring distant details into view. They have 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, these binoculars are water, dust, and fogproof, and their rubber armoring protects the housing and provides a pleasant and secure grip.Optical Performance
