The 13-7501 model is even hermetically sealed to further assure that 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, all three models not only float but easy-grip rubber armoring protects and provides a secure hold should things get rough. Always nice, should an unexpected swell or throttle burst take you by surprise.
