Celestron 10x42 BAK-4 Outland X water proof multicoated Binocular (Green) weather proof roof prism
 
he green 10x42 Outland X Binoculars from Celestron feature multicoated optics, BAK4 Roof Prisms, a wide angle of view, and weather-proof construction with rubber armoring. While the multicoated lenses increase transmission and image brightness, the Roof Prisms made of BAK4 optical glass preserve true colors. The wide 5.6° angular field of view allows you to see a linear field of 293' at a distance of 1000 yards, and the center focus with a diopter allow seeing crisp details as close as 14.8'. These binoculars also have a 56 to 74mm interpupillary adjustment range, a 4.2mm exit pupil and 14mm eye relief.
In addition to optical performance features, the Outlander X presents a number of convenience and construction highlights. The binoculars' housing is nitrogen-purged, waterproof, and fogproof, with a smooth green rubberized armoring to ensure a non-slip grip. For easy focusing, there is a large knurled center focus knob and a ribbed diopter ring on the right eyepiece. To accommodate anyone with glasses, the eyepieces have twist-up eyecups. If you want to attach the binoculars to a tripod, use the threaded hole under the front center cup with an optional adapter.
Also included with the binoculars are a soft neoprene carry pouch, a strap, and protective objective lens cups.
