Military Marine 7x50 binoculars are Waterproof optics by Steiner of Germany. Strength and light weight join forces in these waterproof binoculars. More resistant to extremes of temperature and atmospheric pressure than typical binoculars, these rubber armored binoculars can stand up to years of use on the water or in the field. Industry leading lens coatings on the finest optical glass deliver legendary Steiner clarity, while the 50 mm objective lens keeps the view bright even in the lowest light. Based on the nearly indestructible Steiner military-spec 7x50 chosen by the U.S. Army, these glasses will last a lifetime or longer.
