Vortex Diamondback 10x42 Binoculars

The Vortex Diamondback binocular is an exceptional binocular for its price class. The wide 6.6° field of view makes locating wildlife easy compared to binoculars with smaller fields of view. Full optical multicoatings and phase-correcting coatings on the roof prisms boost brightness and contrast, aiding in the detection of animals under less-than-ideal conditions.
