Silva Eterna Marina 3 7x50 Binoculars
With porro prism design and large light throughput these binoculars are 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!
