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
  • Nitrogen-filled and O-ring sealed to be waterproof, and resistant to internal fogging when moving through extreme temperature changes
  • Protective rubber armor provides a slip-resistant grip
  • Textured palm pads improve grip security and stability — especially in wet weather
  • Tethered one-piece ocular rainguard and objective lens caps prevents their loss while staying close at hand
  • Weight: 22 ounces
