Bushnell Engage Binoculars 8x42mm
Built with a magnification and objective lens combination favored the world over and designed with complementary features that will make it your constant companion.
To deliver peak performance, they are outfitted with extra-low-dispersion (ED) glass, broadband anti-reflection fully multi-coated optics, dielectric coated and phase-corrected BAK4 roof prisms, and protective exterior lens coatings that work together to maximize light transmission through the entire light path without color fringing. 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 such as at dawn and dusk or when viewing across vast wide open spaces. To further improve the observational experience, the Engage binoculars are designed with a long eye relief and comfortable exit pupil as well as a wide 65° apparent angle of view. This minimizes the distracting hand shake that is common with powerful optics and presents a spacious field of view.
Bushnell built the Engage binoculars to make them easy and comfortable to hold and allow them to withstand the harshest elements. Their design provides an ergonomic and balanced feel in the hand that also provides the strength and stability required of workhorse binoculars like these. The optical tubes are nitrogen-filled and O-ring sealed to an IPX7 rating, so they are waterproof and resistant to internal fogging if the weather turns or they take an accidental spill in a stream or puddle. Protecting the optical components is rubber armor outfitted with textured palm pads that provide a sure and secure grip. For those who experience fatigue when holding large optics for long periods, or to simply eliminated vibrations, the Engage binoculars can be tripod-mounted using an optional adapter for easy hands-free use.
Optical Performance
- Moderate 8x power magnifies view while maintaining a long eye relief and wide field of view and exit pupils
- Larger 42mm objective lenses improve light-gathering ability for enhanced low-light performance such as at dawn and dusk or when peering into dense brush
- Compact roof prism light path ensures the optical tubes remain slim for easier handling without affecting performance
- ED Prime extra-low dispersion fluorite glass lens elements reduce chromatic aberrations for increased contrast and improved color rendition and sharpness without fringing across the entire field of view
- 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 light throughput to 92% for minimal loss and diffraction
- Index-matched broadband anti-reflection fully multi-coated optics are specifically engineered to match each lens element to further improve light transmission, contrast, and color fidelity across the entire visible spectrum
- Proprietary EXO exterior lens coatings resist external fogging, scratches, and abrasions while allowing oil, dirt, and sap to be cleaned off without leaving smudges or residue
- Wide 65° apparent angle of view presents an immersive and panoramic observational experience
- Spacious 426-foot field of view at 1000 yards
Use and Handling
- Closed bridge design provides a solid and stable platform for the internal focus mechanism
- 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 without the risk of movement
- Broad 53-72mm interpupillary distance adjustment range enables easy use by a wide variety of users from adolescents to adults
- Twist-up click-stop eyecups for easy use with or without eyewear
- Tripod-mountable with an optional adapter for hands-free use to eliminate vibrations and arm fatigue
- Exceptional 19mm eye relief improves viewing comfort with reduced eyestrain, especially during long glassing sessions
- Wide 5.25mm exit pupil will cover pupils as they open and fully dilate in low light to keep the whole scene in view without vignetting
Construction Details
- Eco-friendly lead-free glass
- Ergonomic body design positions the hand over the binoculars' center of balance for additional comfort and reduced strain and fatigue
- Protective rubber armor with raised palm pads provides a solid and secure slip-resistant grip
- Nitrogen-filled and O-ring sealed to an IPX7 rating: waterproof and capable of temporary submersion in puddles or shallow streams
- Tethered objective lens caps protect lens surfaces without the fear of losing them when not in use
