Konus Regent-HD Features The Konus Regent-HD binoculars use BaK-4 roof prisms composed of barium glass to produce a brighter image while keeping the overall body compact through overlapping prism alignment. Multi-coated lenses apply a layered treatment across each lens surface improving light transmission and boosting image brilliance and clarity. The wide angle W.A. system provides a larger field of view than a standard configuration at the same 10x magnification making it easier to track moving game or scan a wide area quickly. A center focus wheel allows for smooth simultaneous adjustment of both barrels for fast target acquisition in the field. A long eye relief design reduces eye strain and improves comfort for users who wear glasses while individual diopter adjustment of plus or minus 2 compensates for differences between the shooter s eyes. The binoculars are fully waterproof and fogproof standing up to rain humidity and temperature swings without fogging the internal optics. Interpupillary distance adjustment lets users dial in a comfortable properly aligned view regardless of face width. Wrapped in black rubber armor at 24.60 ounces the Konus Regent-HD offers a durable weather-ready package for hunters and anyone who spends time glassing the outdoors.
