DIAMONDBACK HD 20-60X85MM SPOTTING SCOPE Glassing out west demands an HD optic, but other systems can't get you the clarity you need to see a tail twitch in low light, or pick a tine out of dense cover. The redesigned Diamondback HD spotting scopes have all the horsepower the long-distance hunter needs, and they excel in low light - right when you need it most. We've also streamlined the exterior for a sleeker, snag-free profile, building in a helical focus wheel. Mfg: Vortex Optics
