Eterna Marine 3 7x50 No colour

With porro prism design and large light throughput the Eterna Marine 3 7x50 from Silva is intended primarily for marine use. A key feature is the individual focusing function that, after a one-off adjustment for individual eyesight, gives the freedom to directly focus on a desired object without manual focusing! Perfect in rough seas. Rugged, robust and of course waterproof. If you should be unlucky enough to drop them in the water, Eterna Marine will float!
