Nikon Action EX 7x 50 Binoculars. The newest ATB offering from Nikon is modeled from the best selling Action series roof prism binocular. Like all ATB's, the Action EX is nitrogen filled & o-ring sealed for years of waterproof, fogproof & shockproof performance. A truly extreme & rugged binocular, the Action EX is built on an all-metal chassis with all optical components installed in a lightweight polycarbonate shell. The Eco-Glass lens system provides bright & tremendously clear images, while the streamlined body is rubber coated for a non-slip grip wet or dry.
