Designed to be your go-to optic for long-range/low-light use in wide open and expansive terrain, like the plains of the American West, the brown Bushnell 15x56 Forge Binoculars provide a superior viewing experience by combining well-engineered optics and a wide field of view with an ergonomic housing and a suite of accessories to make you more comfortable.

To deliver peak performance, they are outfitted with extra-low dispersion (ED) glass, broadband anti-reflection fully multicoated optics, dielectric coated and phase-corrected BAK4 Abbe-Koenig roof prisms, and protective exterior lens coatings that work together to maximize light transmission through the entire light path without distortion or color fringing across its expansive field of view. The results are bright, sharp, and clear high-contrast views with accurate color fidelity and crisp resolution across the entire visual spectrum, even in challenging conditions.


Optical Performance

  • Designed for extreme long-distance and low-light use
  • Powerful 15x magnification, allowing detailed observation and identification of distant subjects
  • Oversized 56mm objective lenses draw in massive amounts of light to deliver bright views, even in pre-dawn or deep dusk conditions
  • Compact Abbe-Koenig roof prisms help to maintain a slim form factor for easier handling and carrying
  • BAK4 prism glass delivers a round exit pupil and a crisp and clear image with limited edge distortion
  • PC3 phase-correcting prism coatings eliminate internal interference to improve color and contrast
  • Dielectric prism coatings boost surface reflectivity to greater than 99% for maximum light transmission through the prism with minimal loss and diffraction
  • Extra-low dispersion (ED) glass lens elements reduce chromatic and spherical aberrations for increased contrast and improved color rendition and sharpness without distortion across the entire field of view
  • Broadband anti-reflection fully multicoated optics maximize light transmission and improve contrast and color fidelity across the entire visible spectrum
  • Proprietary EXO Barrier exterior lens coatings allow oil, dirt, and sap to be cleaned off without leaving smudges or residue
  • Ultra-wide apparent angle of view presents an immersive observational experience that minimizes the appearance of distracting hand-shake and the need for excessive side-to-side head movement to see the terrain
  • 235-foot field of view at 1000 yards

Use and Handling

  • Open-bridge/dual-hinge design reduces weight without sacrificing stability and offers more gripping surface for steadier handling
  • Large slip-resistant center focusing wheel is easy to manipulate in cold and wet weather, even while wearing gloves
  • Locking right-eye dioptric correction allows user to compensate for optical prescription to produce sharper views with the ability to set it in place to avoid accidental adjustment
  • Twist-up eyecups for easy use with or without eyewear
  • Exceptional 21mm eye relief improves viewing comfort while minimizing eye strain
  • 3.7mm exit pupil will cover most pupils as they open and dilate in low-light conditions, providing clearer views

Construction Details

  • Ecologically friendly lead-free glass
  • Protective armor helps to cushion minor impacts
  • Aggressive armor texture and thumb rests provide a solid and secure slip-resistant grip
  • Nitrogen-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions
  • IPX7-rated—submersible to a depth of 3.3 feet for up to 30 minutes
  • Tethered objective lens caps protect the lens surface without the fear of losing them when not in use

Included Items

  • Objective lens caps: Tethered design allows them to protect the lens surface without the fear of losing them when not in use
  • Neck strap: Padded strap offers improved comfort versus standard strap designs
  • Binocular harness: Replaces the stock neck strap and shifts the weight to your shoulders which reduces stress, strain, and fatigue during long days on the trail
  • Tripod adapter: Normally sold separately, the quick release adapter gets installed on the front of the bridge hinge and allows you to mount the binocular on most tripod, heads, and quick release plates to enjoy hands-free glassing without arm fatigue
  • Case: Made of semi-rigid EVA foam, the case offers protection without being too heavy or bulky
