Zerotech Vengeance ED Features The ZeroTech Vengeance ED 8x42 is built around premium ED extra-low dispersion glass which eliminates the color fringing and distortion that lesser glass introduces at the edges of the field of view. Paired with BAK-4 roof prisms this glass delivers razor-sharp resolution and exceptional contrast across the full 7.5 degree angular field of view and 393 foot linear field of view at 1000 yards. A 9.8 foot close focus distance lets users glass subjects at near range as easily as at distance while 17.5mm of eye relief keeps the view comfortable for eyeglass wearers. These optical specifications combine to give hunters and birders a wide bright stable image whether tracking fast-moving wildlife or scanning terrain at dawn. Built with a fully waterproof and fog-proof chassis the Vengeance ED 8x42 is finished in ergonomic rubber armor that resists shock and slipping even in wet or cold conditions. An adjustable interpupillary distance of 56 to 74mm accommodates a wide range of users and the binoculars are tripod adaptable for steady extended glassing sessions. At 6 inches in length the compact body stays manageable in the field without sacrificing the 42mm objective lenses that gather the light needed for dawn and dusk use. Backed by a manufacturer lifetime warranty the Vengeance ED 8x42 is a durable field-ready optic built for daily use in demanding outdoor conditions.
