Named after the Diamondback rattlesnake, the Vortex Diamondback Binocular detects game in low light strikingly well. The Diamondback's excellent low light performance is largely thanks to fully multi-coated lenses, phase correction, and a roof prism. The Diamondback series also features rubber armor to stand up to bumps and minor impacts, and is compatible with tripods for more stability and longer glassing sessions.
