The Swift 820 Audubon Birding Binocular is a wide field, rubber armored, waterproof binocular designed by Mr. Tamura of Tamura Optical Company from specifications gleaned from a Swift survey of the world's leading ornithologists. Since then, there have been 3 Audubon Binocular models produced using the same formula, which has become famous worldwide for its superior performance and dependability. The Swift Audubon binoculars have been rated "best buy" by the Cornell Laboratory of Ornithology, Better View Desired, and the english publication British Birds. To this optical formula, which has a 5-lens ocular system, BaK4 prisms and a fully multi-coated optics, we have added a waterproof, rubber coated body, made of magnesium to reduce weight. An extra high eye point, and pop-up eyecups add comfort for eyeglass wearers. This top performance birding binocular will produce crisp, high definition images to the outer limits of the wide field and will close focus to under 10 feet. Supplied complete with padded hard case and a comfortable broad woven neck strap. Gift boxed.
