Overview

The Chrom-4 10X42 binoculars feature fully coated optics, Bak-4 roof prisms, a wide field of view, and water-resistant construction with durable armoring. While the multicoated lenses increase transmission and image brightness, the roof prisms made of Bak-4 optical glass preserve full round exit pupil and true color. The wide 5.4° angular field of view allows you to see a linear field of 283' at a distance of 1000 yards, and the central focus with a diopter allows seeing crisp details as close as 9.84 ft. The binocular also has a 56-74 mm interpupillary adjustment range, a 4.2 mm exit pupil and 14.8 mm eye relief.

In addition to optical performance features, the Chrom-4 presents a number of convenience and construction highlights. For easy focusing, there is a large knurled center focus knob and a ribbed diopter ring on the right eyepiece. To accommodate anyone with glasses, the eyepieces have twist-up eyecups. If you want to attach the binocular to a tripod, use the threaded hole under the front center cup with an optional adapter.

Optical Performance

  • High 10x power enables detailed observation and identification at long range
  • 42mm objectives boost low-light performance without adding excessive bulk and weight
  • Compact roof prism design maintains a slim form factor without sacrificing performance
  • BAK4 prisms glass delivers a round exit pupil and a crisp and clear image with limited edge distortion
  • Anti-reflection fully coated lenses improve light transmission for bright and clear images with accurate color rendition
  • 283' field of view at 1000 yards

Use and Handling

  • Closed bridge configuration
  • Large slip-resistant center focusing wheel is easy to manipulate in cold or wet conditions or when wearing gloves
  • Right-eye dioptric adjustment allows for precise focusing for sharper and clearer views
  • 56-74mm interpupillary adjustment range allows easy use by a wide variety of users
  • Twist-up click-stop rubber eyecups for comfortable use with or without eyewear
  • Tripod mountable with optional adapter
  • Comfortable 14.8mm eye relief reduces eyestrain for easier viewing
  • Wide 4.2mm exit pupil will cover most pupils as they open in low light to keep the entire scene in view at all times

Construction Details

  • Environmentally-friendly lead-free glass
  • Plug-in objective caps and one-piece ocular rainguard provide optimum protection against rain and dust while remaining close at hand without the possibility of losing them
  • Durable armoring protects against bumps and impacts while offering slip-resistance to the grip
  • Weight: 20.99 ounces
