Silva Eterna Navigator 3 7x50 Marine Binoculars with Compass

7x50 Nautical Binoculars with Integrated Compass for Marine Navigation

The Silva Eterna Navigator 3 7x50 is the nautical binocular built for those who truly navigate at sea. Robust, waterproof and equipped with an integrated compass, it is a complete instrument for keeping course and horizons under control in any sea condition. The Eterna series was developed with a clear objective: to deliver high-level optical performance in a body capable of withstanding the most demanding marine environment.

The BAK-4 Porro prisms combined with the 50mm objective lens ensure high light transmission — essential at dawn and dusk or under overcast skies. The fixed focus eliminates any manual adjustment during navigation: once calibrated to personal eyesight, the binoculars are always ready to use — even with one hand, even in rough seas. The integrated compass allows immediate bearings without the need for separate instruments.

The body is nitrogen gas filled to eliminate the risk of internal fogging even in the humid conditions typical of the marine environment. The IPX7 certification guarantees waterproofing even in the event of accidental immersion — and should it end up in the sea, the Navigator 3 floats.
