Let there be light! With 56mm objective lenses, Vulture® HD series binoculars deliver absolutely incredible light transmission and superior low light performance—a critical attribute at dawn and dusk when game can be most active. And the phase-corrected roof prisms, fully multi-coated optics and our proprietary XR™ coatings deliver a super-bright image that’s sharp from edge-to-edge. Our proprietary ArmorTek coating on all exterior lenses resists scratches and smudges.
