Waterproof, fogproof, and nitrogen-filled, these binoculars are designed for use on the water. Molded finger grips provide a sure grip, while ruby-coated lenses reduce water surface glare. Best of all, they'll float if accidentally dropped overboard. Also feature center focus, BAK-4 prisms, and retained lens caps. 7 x 50 power. 6.6° field view angle. 116m field of view at 1000m.
