Leupold Golden Ring 7/12x32mm Switch/Power Binocular 62710 is the easiest to use multi-magnification level premium binocular among all premium performance binoculars because of its unique Switch/Power technology that allows for instant switching between magnification level without loosing sight of the object being viewed. Leupold Golden Ring 7/12 x 42mm Binocular with Switch/Power Technology features a precision-structured switch in front of the focus ring that instantly and fully changes the power setting, so the object you're viewing always stays at the center of the visual field. Scan at 7x, then with a flick of your finger, you're viewing at 12x, without ever taking your eyes off your target. This is no zoom, zooming can cause you to lose track of what you're viewing, as it moves up in magnification and the visual field narrows. It's like carrying two binoculars, and these zoom binoculars are as easy to use as a light switch. The Leupold binoculars also offer outstanding optical performance, thanks to fully multicoated lenses, BAK4 prisms, and phase coated roof prism and L-coat (64-layer dielectric) enhanced auxiliary prisms for incredible brightness and superior resolution across the entire visual field. Extremely rugged and absolutely waterproof with Leupold's proprietary Argon/Krypton gas blend. Leupold GR 7 / 12 x 42mm Switch / Power Brown Binoculars are covered by the Leupold Full Lifetime Guarantee. Packaged with both flat top and contoured interchangeable eyecups, one-piece eyepiece and tethered individual objective covers, a Leupold quick release carrying harness, a padded-edge neoprene neck strap, and a custom zip top padded case. Hunting, birding, camping, hiking, or even at sporting events or concerts, anytime you use binoculars, you'll want Leupold Golden Ring 7/12x42 binoculars with Switch/Power Technology.
