Designed based on specifications gleaned from a Swift survey of the world’s leading ornithologists, the Swift Audubon binoculars have become famous worldwide for superior performance and dependability. The 820 Swift Audubon has been rated “best buy” by Cornell Laboratory of Ornithology, Better View Desired, and the English publication, British Birds. They are equipped with a 5-lens ocular system, BaK4 prisms, fully multi-coated optics and pop and lock eyecups adding comfort for eyeglass wearers. The Swift Audubon produces crisp, high definition images to the outer edges of the wide field and close focuses to under 10 ft. The rubber-coated body is made of magnesium to reduce weight and is sealed to make the binoculars waterproof. Padded hard case and comfortable broad woven neck strap included.
