SEA AND LAND
Although designed for use at sea, the Silva Eterna Marine Binoculars will function just as well on land. Technical features include a 116mm field of view with 7X magnification through a 50mm lens and Bak-4 type prism. The unit is tough and waterproof, filled with nitrogen gas, floats if dropped over board and easily located thanks to a bright yellow colour scheme.
