A truly extreme and 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 and tremendously clear images, while the streamlined body is rubber coated for a non-slip grip wet or dry. The Action EX is nitrogen filled and o-ring sealed for years of waterproof, fogproof and shockproof performance.
