Bushnell Marine Binoculars
Bushnell Marines are built to withstand the conditions that come along with the nautical world, they are not only nitrogen-purged to provide reliable waterproof/fogproof performance, and some models are even hermetically sealed to further assure no moisture creeps in. Impressive light transmission from BaK-4 porro prisms, multi-coated optics and large UV-coated objective lenses brighten images from dusk-to-dawn. And they not only float, but easy-grip rubber armoring protects and provides a secure hold should things get rough.
