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.

Product Highlights

  • Open-Bridge Design: Intuitive open-hinge structure dramatically improves deck handling and enables confident one-handed gripping for safe, uninterrupted navigation.
  • Auto Sport Focus System: Set each eyepiece once to your vision and enjoy razor-sharp images from 20 yards to infinity without ever needing to refocus on moving targets.
  • Hi-Contrast Multicoated Optics: Advanced multi-layer lens coatings and index-matched high-definition glass deliver exceptional brightness, contrast, and edge-to-edge clarity even in challenging light or fog.
  • Rugged Makrolon Housing: Polycarbonate body with NBR Long-Life rubber armoring withstands 11G impacts, is submersible to 5 meters, and operates reliably from -20°C to +70°C.
  • N2 Injection System: 14-psi pressurized dry nitrogen fill permanently prevents internal fogging, ensuring optical clarity from arctic cold to desert heat.
