Used for general-purpose observations from birdwatching to hunting to sightseeing, the Opticron 8x32 Adventurer II WP PC Binoculars feature a moderate magnification for bringing subjects in close, and an objective lens diameter that provides extended performance in low light without the bulk of larger lenses. Outfitted with phase-corrected BAK4 roof prisms and fully multicoated optics, they deliver high-contrast images that are bright and clear with accurate color representation. An exceptionally long eye relief helps boost the comfort-level during extended observation sessions and reduces eye fatigue.

The compact design of the prism system ensures a slim form-factor for easy packing and carrying. The body is made using both aluminum and polycarbonate for strength and durability. The entire optic is designed with a neutral weight distribution to ensure the center of gravity sits naturally in your hand to prevent arm fatigue. Protective rubber armor and raised palm pads provide a slip-resistant grip. 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 ensure they remain close at hand when needed and a one-piece ocular rainguard allows for fast deployment in the field.
