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.

Optical Performance

• High 10x magnification for making detailed observations of distant objects
• 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
• 294-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
• 15mm eye relief makes long-duration observation sessions comfortable with reduced eye strain
• 4.2mm exit pupil will cover pupils as they open and dilate in low light

Construction Details

• Lightweight and sturdy aluminum and polycarbonate construction
• Neutral balance makes them comfortable in the hand to reduce fatigue during long glassing sessions without a support system
