Bushnell 171073 10x42 PermaFocus Roof Prism Binoculars

Never lose focus on the action again--the Bushnell Perma Focus Binoculars keep you dialed in on your target at any long-distance range with no adjustments necessary. Simply raise them to your eyes and catch the action instantly. With 10x magnification and 42-millimeter objective lenses and the porro lens system, these binoculars maintain a large field of view to catch the action at sporting events and in nature. On cold days you will appreciate not having to take your gloves off to adjust the focus. With precision-crafted, BK-7 prisms and fully coated optics, the binoculars offer bright, crisp images even at low light. And the ergonomic rubber housing provides a secure grip--even with gloves on. Built to last, the Perma Focus 10x42 Binoculars carry a limited lifetime warranty from Bushnell.
