Carson JR-842 overview

  • 1Description

Carson Optical designed the 8x42 JR Close-Up Binocular with a magnification and objective lens size favored by birders, boaters, hunters, hikers, and outdoor enthusiasts for its performance and versatility — ensuring that it will quickly become an essential piece of your kit.

Its wide exit pupil and long eye relief, when coupled with the enhanced light-gathering ability of the objectives, makes it ideal for use in all light conditions from the pre-dawn hours through the day and well into dusk. Complementing these features are compact BAK4 roof prisms and anti-reflection fully multi-coated optics, which maximize light transmission and produce high-contrast images with accurate color fidelity and improved clarity.

To withstand the rigors of the trail, Carson nitrogen-filled and O-ring sealed the optical tubes to be waterproof and resistant to internal fogging in extreme temperature and weather conditions. The chassis is wrapped in a protective rubber armor that is textured to provide a slip-resistant grip in cold and wet weather. For long-duration glassing sessions at the range, in a blind, or on a patio, the JR Close-Up can be tripod mounted with an optional adapter to provide easy hands-free use with greatly reduced vibrations and no arm fatigue. Ideal for hiking and boating, Carson includes tethered objective lens covers and an ocular rainguard to protect exposed lens surfaces and stay close at hand without the risk of losing them.

Optical Performance
  • Moderate 8x power magnifies view without sacrificing field of view, exit pupil, and eye relief to make use more comfortable in all light conditions
  • Larger 42mm objective lenses boost light-gathering ability for enhanced low-light performance such as at dawn and dusk or when peering into dense brush
  • Compact roof prism optical path ensures a slim form factor for easier handling without sacrificing performance
  • BAK4 prism glass produces a round exit pupil, with crisp and sharp images free from edge distortion
  • Anti-reflection fully multi-coated optics maximize light transmission to produce bright and clear high-contrast views with accurate color fidelity
  • 315' field of view at 1000 yards
Use and Handling
  • Closed bridge configuration provides a solid platform for the internal focusing mechanism
  • Large slip-resistant center focusing wheel is easy to manipulate in cold and wet weather, or while wearing gloves
  • Right-eye dioptric correction enables users to compensate for individual optical prescription for clearer and sharper images
  • Twist-up rubber eyecups for comfortable viewing with or without eyewear
  • Tripod mountable with optional adapter for hands-free use to eliminate vibrations and arm fatigue
  • Exceptional 21mm eye relief makes viewing easier and more comfortable, with reduced eye strain—especially during long-duration observation sessions
  • Wide 5.25mm exit pupil will cover pupils as they open and dilate in low light to keep the entire scene in view without vignetting
