Guaranteed waterproof, a new more compact design, with the brightness expected from Steiner, this 7x50 Navigator model is everything you'd want in a lightweight, marine binocular. Like all our marine binoculars, Navigators feature Steiner's Sports Auto Focus system that, once set for your eyes, puts everything from 20 yards to infinity into sharp, clear focus, with no further adjustment. In the cockpit or on the dock, you won't miss a thing with Steiner Navigators.
