Outfitted with a configuration favored by birders, hunters, and outdoor enthusiasts who work at long-ranges, the Opticron 10x42 Adventurer II WP Binoculars feature high power for bringing far-off subjects in close, and an objective lens diameter that provides extended performance in low light without excessive bulk. Outfitted with BAK4 roof prisms and fully multi-coated optics, they deliver high-contrast views that are bright and clear with accurate color representation. Their 15mm eye relief helps boost the comfort-level during extended observation sessions and reduces eye fatigue.

The binoculars' body is made using both aluminum and polycarbonate to make them strong and durable, and is designed with a neutral weight distribution that ensures the center of gravity sits naturally in the hand to help prevent arm fatigue. Protective rubber armor and raised palm pads provide a slip-resistant grip, while their large textured focus wheel makes them easy to use — especially in cold and wet weather, or when wearing gloves. The optical tubes are nitrogen-filled and O-ring sealed to make them waterproof, and to prevent internal fogging when moving through extreme temperature and environmental conditions. Tethered objective lens caps and a one-piece ocular rainguard ensure they are close at hand when needed and allows for fast deployment in the field.
