DISCONTINUED: Please call for alternatives.

The Eagle Optics Ranger ED 8x42 binocular is brand new, incorporating extra-low dispersion (ED) glass with phase-corrected prism coatings for bright contrast and resolution, fully multi-coated lenses with anti-reflective surfaces for increased light transmission. What's really great about the new Ranger is its 5.2 foot close-focus, perfect for birders and nature enthusiasts while also maintaining a large 341ft field of view. A locking diopter ring eliminates diopter drift. The Eagle Optics Ranger is constructed with a light-weight waterproof, and fogproofed polycarbonate body. The twist-up eyecups, generous 19.5mm eye relief and tripod adaptable body make for ultra comfortable and accurate observation. The Ranger ED will take your outdoor pursuits to new levels!

In Depth Features:


ED glass: The Ranger ED series bring about a remarkably sharp resolution and contrast-rich image thanks to their Extra-low Dispersion Glass or ED Glass for short. It is used in the finest optics and used by professionals who require the details in an image to be clear and bright. The ED Glass reduces ‘color-fringing’ thanks to its ability to keep differing wavelengths of light together which also increases the resolution of the image so that all details are bright, and color-accurate as in the image above.


Multi-Layer Lens Coatings: This basically means that the lenses have received multiple layers of anti-reflective coatings on all air-to-glass surfaces which increase light transmission to produce a brighter image and therefore better low light performance. Anti-reflective coatings can make a really big difference on the brightness of the image produced. It is not unusual to look through binoculars with smaller objective lenses, but with higher quality anti-reflection coatings and seen them outperform binoculars with much larger objective lenses, but with fewer or no coatings. The diagram above shows how these coatings improve the transmission of light.
