Bushnell H2O Series Binoculars

The H2O 10x42 Porro Binocular (Blue) from Bushnell was built to sail the ocean blue, row down a rolling river, or accompany a raft on a languid lake. It has been o-ring sealed and nitrogen purged for waterproof and fogproof protection. Immersed in water, they will still stay dry inside, and the interior optical surfaces won't fog due to a rapid change in temperature or humidity. To make them even more aquatically acclimated, the protective rubber armoring is a blue color with a soft textured ridged grip so they won't slip too easily out of the hand and into the hydrosphere even when wet. The magnification of 10 power with the 42mm objective provides excellent viewing for both close-up detail and scanning the field of view. The comfortable size allows the binocular to remain easy to hold steady even on the deck of a deep-water frigate riding the ocean swells. Multi-coated lenses and premium BAK4 prism glass assure superior optics that delivers maximum light transmission and clarity.
