The Bushnell 10×42 Engage Binocular is designed with complementary features that will make it your constant companion, and is ideal for when you’re out birding, hunting, hiking, camping, or enjoying sporting events—especially in wide-open spaces where the high magnification and wide field of view really shine.

Key Features

  • Extra-Low Dispersion Glass Objectives
  • Eco-friendly Lead-Free Glass
  • Compact BAK4 Roof Prisms
  • Dielectric Coated and Phase Corrected
  • Broadband Fully Multi-coated Optics
  • Protective EXO Exterior Lens Coatings
  • Wide 65° Apparent Angle of View
  • Nitrogen-filled, Waterproof & Fogproof
  • Tripod-Mountable with Optional Adapter
  • Twist-up Click-Stop Rubber Eyecups

To deliver peak performance, they are outfitted with Extra-Low Dispersion 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 colour fringing.

The results are bright, sharp, and clear high-contrast views with accurate colour 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 Binocular are designed with a long eye relief and comfortable exit pupils 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 Binocular to make it 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 Binocular 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 a 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 eliminate vibrations, the Engage Binocular can be tripod mounted using an optional adapter for easy hands-free use.

Optical Performance

  • High 10x magnification enables detailed observations of distant subjects
  • 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 with reduced appearance of the distracting hand-shake that is common when holding high-power optics
  • Spacious 340-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 18mm eye relief improves viewing comfort with reduced eyestrain, especially during long glassing sessions
  • 4.2mm exit pupil will cover most pupils as they open and dilate in low light to keep the whole scene in view without vignetting
