"The Bushnell Legend Ultra HD 15-45x 60mm Spotting Scope is small enough to fit into a backpack yet it delivers brilliant viewing and it's built to last. The Legend's optics are first-rate - ED glass lenses ensure excellent viewing performance and they're fully multicoated for optimum viewing in any situation. Inside the Legend's durable rubber armored housing, a high-quality BAK4 porro prism ensures maximum clarity and contrast. The exterior lens surfaces have been treated with RainGuard HD - a water repellent coating that disperses water, mist and fog for maximum clarity in any climate. Boasting a rotating tripod collar and stacked dual-focus knobs, this Legend Ultra HD is a breeze to set up and gets on target just as fast.
