The Steiner Navigator 7x50 is truly made for use on the water. The new open-bridge construction makes it very easy to hold, even with one hand. A special rubber coating and texture has been used, so that you still have good grip even when the binoculars are wet. The Steiner Auto-Focus ensures that you have a razor-sharp image, from 20 m to an infinite distance. This is useful for identifying beacons and bridge numbers, even in rough weather conditions.
