Check the listing for details. VORTEX OPTICS DIAMONDBACK HD 16-48x65 (STRAIGHT) - NEW. Condition: New. Listed at 399.00 USD. 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 lowlight—right when you need it most. We've also streamlined the exterior for a sleeker, snag-free profile, building in a helical focus wheel.
