The Gerber Nautica 7x50 Waterproof Binoculars with in built compass are the perfect companion for use near water. Fully waterproof in design, these fantastic binoculars are designed to float in water rather than sinking if you accidentally drop them over the side of your boat! Not only are these 7x50 Gerber binoculars great for use on lakes, rivers or at sea, they are also perfect for use at all sporting events and for everyday magnification. The large 50mm objective lenses on these Gerber binos provide a large field of view and are good at capturing light, making them great for use in lower light conditions or for catching all the action at a ball game. These marine binoculars include a canvas carry case and soft padded carry strap and as the front lens covers are permanently attached there is no need to worry about losing them. Power 7X Obj.
