Vortex Diamondback 10x42 Binocular is a superb bird watching binocular. The Vortex Diamondback Binocular taking their lead from the Diamondback's namesake, these rugged binoculars are striking in how well they detect subtle colors. Not only do the Diamondbacks boast the widest field of view around, but fine optics that pierce through dark, shadowy areas with bright, steady views. No wonder the Diamondbacks are a favorite for virtually any outdoor activity!
