Bushnell 10 x 42 Natureview Plus Binocular
Bushnell Natureview birding series binoculars combine outstanding optical quality with rugged construction that can stand up to wilderness and field use. Thanks to BaK-4 prisms and fully multi-coated optics, all Natureview binoculars provide high-level image clarity and brightness for near and far views. The 10x42 Natureview Plus Binoculars offer 10x magnification with a roof prism optical system that reduces the overall weight of the binoculars while adding to their sturdiness. The binoculars have 42-millimeter objective lenses for increased light-gathering capabilities at twilight hours. Thanks to O-ring seals and nitrogen purging--the Natureview Plus Binoculars are 100 percent water and fog proof. These binoculars can withstand complete immersion in water without compromising the optics. In addition the interior surfaces will never fog-up due to rapid temperature change or humidity. Additional field and user friendly details include extended eye relief for greater user comfort, a rugged, shock-absorbing non-slip exterior for a secure grip and to protect the optics, and a textured center focus knob for precise adjustments. Bushnell Natureview Plus Binoculars carry a limited lifetime warranty against defects in materials and workmanship for the original owner.Key Features:BaK-4 prisms for bright, clear, crisp viewingFully multi-coated optics for enhanced light transmission and brightnessRoof prism system100 percent water/fogproof constructionNon-slip, and shock-absorbing rubber armorCenter focus system with textured knobTwist-up eyecupsTripod adaptableSpecifications:Magnification: 10xObjective Lens: 42 millimetersClose Focus: 12 feet / 3.6 metersField of View: 315 feet at 1000 yards / 105 meters at 1000 metersEye Relief: 17 millimetersExit Pupil: 4.2 millimetersWeight: 25.6 ounces / 725 gramsModel: 221042Size Class: StandardAbout Roof Prism Binoculars:The prism system of a binocular reduces the size needed to contain a long optical path and turns what would be an upside-down image right-side-up. In roof prism binoculars, the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, streamlined shape in which the lenses and prisms are in a straight line. Roof prism binoculars are less bulky and more rugged than an equivalent porro model.
