Glassing out west demands an HD optic, but other systems cant 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 lightright when you need it most. Weve also streamlined the exterior for a sleeker, snag-free profile, building in a helical focus wheel. For the biggest hunt of your year, or your third time out this season, the all-new Diamondback HD spotters deliver the power to focus on the thrill of your hunt.SpecificationsSKU VT-DS-65AMagnification 16 48 xObjective Lens Diameter 65 mmLinear Field of View 138 72 feet/1000 yardsAngular Field of View 2.6 1.4 degreesClose Focus 16.4 feetEye Relief 20.318.3 mmExit Pupil 4.01.35 mmLength 14.25 inchesWeight 49.8 ouncesOptical FeaturesHD Optical System Optimized with select glass elements to deliver exceptional resolution, cut chromatic aberration and provide outstanding color fidelity, edge-to-edge sharpness and light transmission.Fully Multi-Coated Increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.Construction FeaturesArmorTek Ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt.Waterproof O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments.Shockproof Rugged construction withstands recoil and impact.Fogproof Argon gas purging prevents internal fogging over a wide range of temperatures.Rubber Armor Provides a secure, non-slip grip, and durable external protection.Convenience FeaturesAdjustable Eyecup Twists up and down to precise, intermediate settings to maximize custom fit for comfortable viewing with or without eyeglasses.Helical Focus Allows for fast and fine adjustments.Arca-Swiss Compatible Directly mounts to Arca-Swiss tripod heads without the use of additional plates.
