Vortex Bird Watching Binoculars. The Vortex Vanquish 10x 26 Binoculars feature a reverse porro prism design with high-density glass and fully multi-coated optics that renders images crisp and bright. Vortex Vanquish VNQ-1026 Binoculars are sealed with O-rings to prevent moisture, dust, and debris from getting inside the binocular and the barrels are filled with nitrogen gas to inhibit internal fogging. Vortex Vanquish 10 x 26 Binoculars also have a wide field of view which makes quick work of scanning the landscape for that all-important subject.
