Opticron 8x42 Adventurer II WP Binoculars

Outfitted with a magnification and objective lens diameter favored by birders, hunters, and outdoor enthusiasts, the Opticron 8x42 Adventurer II WP Binoculars feature moderate magnification for bringing 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 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, and the body is made using both aluminum and polycarbonate to make them strong and durable. The entire optic 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.

Optical Performance

• 8x magnification enables observations of subjects without sacrificing exit pupil diameter
• Larger 42mm objective lenses draw in more light than smaller models for better viewing in low-light conditions
• Compact roof prisms help to keep the form-factor slim to be easier to pack and carry while being comfortable to hold
• BAK4 prisms deliver a round exit pupil, and a crisp and clear image with limited edge distortion
• Anti-reflection fully multi-coated optics maximize light transmission to help produce accurate color fidelity, and improve contrast and brightness
• 357-foot field of view at 1000 yards

Use and Handling

• Closed-bridge configuration adds stability while providing a solid platform for the focusing mechanism
• Large textured slip-resistant focusing knob is easy to manipulate precisely, even while wearing gloves
• ± 2 right-eye dioptric correction for precise focus adjustment to most user s individual prescription
• 56-73mm interpupillary adjustment range
• Twist-up rubber eyecups for comfortable use with or without eyewear
• Tripod mountable with optional adapter for hands-free use, and reduced arm fatigue and vibrations
• Long 20mm eye relief makes long-duration observation sessions comfortable with reduced eye strain
• Wide 5.25mm exit pupil will cover pupils as they open and dilate in low light
