Steiner Navigator 7x50 Open-Hinge Marine Binoculars The Steiner Navigator 7x50 Open-Hinge Binoculars (MPN 2342) represent a significant leap forward in Steiner&';s acclaimed marine optics lineup. Engineered for serious mariners, the open-bridge design makes one-handed handling on deck effortless, while a wave-like textured rubber coating ensures a non-slip, secure grip in any weather condition. With a 50mm objective lens and 7x magnification - the recognized marine standard - these binoculars deliver a wide, stable field of view of 419 feet at 1,000 yards, making it easy to identify buoys, beacons, and bridge numbers even in rough seas or low-light conditions. Built with durable Makrolon polycarbonate housing rated to withstand impacts up to 11G, submersible to 5 meters, and nitrogen-filled to prevent internal fogging, the Navigator 7x50 is as rugged as it is optically brilliant. Whether navigating coastal waters or spending extended time offshore, these binoculars are a trusted partner for yacht owners, fishing guides, ship captains, and competitive sailors alike.
