Silva Eterna Navigator 3 Marine Binoculars with Compass

The Silva Eterna Navigator 3 is a premium pair of waterproof marine binoculars designed for sailors, boat owners, anglers and anyone who needs reliable navigation optics on the water. Combining exceptional optical performance with a built-in illuminated compass, these 7×50 binoculars deliver outstanding visibility in challenging marine conditions.

Featuring a classic Porro prism design with high-quality BaK-4 prisms, the Eterna Navigator 3 provides excellent light transmission for bright, sharp images, even at dawn, dusk or in poor weather. The individual focus system ensures precise viewing, while the extended eye relief makes these binoculars comfortable for users who wear glasses.

Built to withstand demanding marine environments, the Silva Eterna Navigator 3 is waterproof, fog proof and nitrogen-filled to prevent internal condensation.
