With high magnification and wide objectives required by birders, hunters, and outdoor enthusiasts who work at long-ranges and in challenging conditions, the Opticron 10x50 Adventurer II WP Binoculars are designed to bring far-off subjects up close while providing extended performance in low light. Outfitted with BAK4 prisms that are phase-coated for color fidelity and fully multicoated optics, they deliver high-contrast views that are bright and clear. Their long eye relief and wide exit pupil boost the comfort level during extended observation sessions and reduces eye fatigue — especially at dawn and dusk or when peering into dense brush or under a heavy wooded canopy.

The aluminum and polycarbonate body makes them strong and durable, and they are designed with a neutral weight distribution to ensure the center of gravity sits naturally in your hand to help prevent arm fatigue. Protective rubber armor and raised palm pads provide a slip-resistant grip, while the 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 allow for fast deployment in the field.
