Your riflescope isn't a fixed power and your binoculars shouldn't be ether. Switch/Power™ Technology with a precision-machined front switch on the focus ring instantly changes the power setting. It's like carrying two pairs of binoculars in one. Scan at 7X, and with the flip of a switch, get a better look with 12X. The same can be done with the 10X to 17X model. The fully multicoated lens system gives you superb brightness, resolution, contrast and color. Phase-coated prisms eliminate diffraction and ensure clarity. And since Leupold paved the way for the truly waterproof optic, it developed an even more reliable waterproofing construction using an argon/krypton gas blend that keeps your binoculars fog-free for a lifetime of use. Can be used with any standard tripod mount, making them even more versatile for the field. Rugged, waterproof and guaranteed for life with Leupold's Full Lifetime Guarantee.
