Product Description

This Bushnell Elite ED 8 x 42mm binocular is the latest and most advanced version of Bushnell's top-of-the-line Elite series. It comes from Bushnell, a company with a proud history of optical innovation and performance that stretches back over 60 years. And you don't stay in business for 60 years, growing constantly, unless you are doing something very right.

This new Elite ED version gets an upgrade this year in the form of ED Prime glass lenses for even finer color correction, and new "RainGuard HD" coatings that shed water from the optics even faster than Bushnell's original industry-first "RainGuard" coatings. It has the right balance of superb true-color performance, excellent light-gathering, and easily hand-holdable magnification to make it your favorite all-purpose binocular, just as it is one of ours.

Features of this binocular . . .

  • Multicoated ED Prime aspheric roof prism optics: The Elite ED uses lens elements of ED Prime (Extra-low Dispersion) glass for the most realistic true-color images ever in an Elite binocular. The low dispersion of the ED Prime glass simultaneously reduces annoying chromatic aberration (color-fringing) to vanishingly low levels as it improves color fidelity. All air to glass optical surfaces are fully multicoated, using special high transmission XTR Technology coating materials for the least amount of light loss per optical surface and the brightest possible images. Overall light throughput (the amount of light collected by the binocular that actually reaches your eye) is a full 90%, the highest in its class. The superior color fidelity of the XTR multicoatings and ED Prime glass makes it easier to resolve subtle species differences, even in poor lighting conditions. In addition, the Elite ED uses advanced Hybrid-Fusion Technology to fuse synthetic molded aspheric elements to optical glass substrates. This results in lenses with complex aspheric curves that deliver superior edge-to-edge definition - lenses that would be impossible to produce with conventional lens polishing techniques.
  • Dielectric roof prism coatings: The Elite ED's roof prisms are precisely fabricated from premium-quality high transmission BaK-4 glass. Instead or aluminum or silver coatings on the prism faces, they use 60-layer XTR dielectric mirror coatings for an astonishing 99.73% reflectivity across the entire visible spectrum, the highest reflectivity in the industry.
  • Phase coated prisms: Special PC-3 phase-correcting coatings are applied to the roof prisms for peak contrast, color fidelity, and resolution. The resulting improvement is easily visible in the color fidelity and detail seen when examining the shadowed areas of a silhouetted or backlit bird.
  • Water-shedding "RainGuard HD" lens coatings: All external optical surfaces (eyepieces and objective lenses) are treated with the latest permanent "RainGuard HD" coatings. These special hydrophobic (water-repelling) coatings are so smooth, even at the molecular level, that water can find virtually no grip on the lens surfaces. This causes the condensation from rain, fog, snow, or your own breath to form in much smaller droplets than on standard optical coatings. Smaller droplets scatter less light, resulting in higher light transmission and a clearer image in poor weather conditions. Bushnell was the first to introduce the "RainGuard" hydrophobic coating advantage to the binocular industry back in 2001. That was six to seven years before other optics manufacturers jumped on the water-shedding bandwagon. Now Bushnell takes another step forward with improved "RainGuard HD" coatings that shed water even faster than those original ground-breaking "RainGuard" coatings.
  • Long eye relief: Eye relief is specified at 19.5mm. Unlike many manufacturers, whose eye relief typically measures a mm or two less than specified due to the recessing of the eyepieces when the eyecups are in the down position for eyeglass use, the Bushnell Elite ED truly provides the full 19.5mm eye relief specified. Vignetting (if any) will be very minor for eyeglass wearers.
  • Body construction: H-body roof prism with internal center focus. The lightweight and durable magnesium alloy body is clad in a durable black armor to take every kind of rough treatment in stride. The armor also insulates the binocular to keep it comfortable to the touch in all temperatures. It is lightly textured to provide a sure grip in wet weather.
  • Weatherproofing: The Elite ED is O-ring sealed and nitrogen-purged to be totally waterproof, fogproof, and dustproof in all climate extremes - from the cold and mists of Attu, to the warm and dripping humidity of the Costa Rican rain forests, to the drenching salt spray of a pelagic birding trip.
  • Focusing: The extra-large ribbed focus knob can be used with either hand. The knob is easy to turn, even while wearing gloves or mittens. The Elite ED close focuses to 8', making it eminently useful for close-in woodland birding.
  • Diopter adjustment: There is a centrally-located diopter adjustment that cannot shift accidentally while in use. The diopter adjustment ring pulls back and rotates to adjust the optics to your eyesight, and then snaps forward to lock in the chosen adjustment. A red band shows on the diopter adjustment ring when it is unlocked, giving you a visual confirmation of its status.
  • Eyecups/RainGuard: Twist-up eyecups with soft rubber rims block ambient light for those who don't wear glasses while observing. The eyecups twist back down into the body to provide extra eye relief for those who must wear glasses or sunglasses while birding. The supplied soft and flexible eyepiece rainguard is easy to remove without disturbing the extended/retracted position of the eyecups.
  • Supplied accessories: The binocular comes with a wide and comfortable soft neck strap. Objective lens covers protect the optics when the binocular is not in use. The molded semi-rigid case is shaped to conform to your hip for more comfort when carrying your binocular at your side with the separate adjustable-length case strap over your shoulder.
  • The new Bushnell 8 x 42mm Elite ED is an outstanding all-around premium binocular that we think compares quite handily with European binoculars that nowadays cost up to three or four times the very reasonable Elite ED price.
