The Coleman® CS1650 waterproof series binoculars were designed for the nautical world and hunting enthusiasts alike. The steady magnifications and large objective lenses are optimal for providing excellent resolution and detail. Fully multi-coated optics and BaK4 prisms ensure a bright, clear image with sharp contrasts and vivid detail. Nitrogen gas inside the binoculars prevents fogging and the accumulation of mold on internal lens surfaces, even under severe and extreme conditions.
