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 multicoated 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 body is made from aluminum and polycarbonate for strength and durability. The neutral weight distribution ensures 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 and 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 you are moving through extreme temperature and environmental conditions. Tethered objective lens caps ensure they are nearby when needed and a one-piece ocular rainguard 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 keep the form-factor slim for easy pack and carry and a comfortable hold
  • BAK4 prisms deliver a round exit pupil plus a crisp and clear image with limited edge distortion
  • Antireflection fully multicoated optics maximize light transmission to help produce accurate color fidelity as well as improved contrast and brightness
  • 294' field of view at 1000 yards
Use and Handling
  • Closed-bridge configuration adds stability and provides a solid platform for the focusing mechanism
  • Large, textured, slip-resistant focusing knob is easy to manipulate precisely, even while wearing gloves
  • Right-eye dioptric offers ±2 correction for precise focus adjustment to most user's individual prescription
  • Interpupillary adjustment range is 56-73mm 
  • Twist-up rubber eyecups for comfortable use with or without eyewear
  • Tripod mountable with optional adapter for hands-free use to minimize arm fatigue and vibrations
  • Eye relief is 15mm for comfortable long-duration observation sessions comfortable with reduced eye strain
  • Exit pupil is 4.2mm and 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 and reduces 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 keeping them handy
  • Weight: 22 ounces
