Bushnell H2O Porro Prism Binoculars
H2O porro prism binoculars from Bushnell are reasonably-priced binoculars in compact and full-sized roof prism design. They are also available in roof prism full size and compact designs. Made with BaK-4 glass prisms for bright, crisp images, H2O binoculars also have multi-coated optics for better light transmission. As the name implies, o-ring seals and nitrogen-purging make Bushnell H2O binoculars completely waterproof and internally fog-proof. Textured rubber armoring provides a secure grip on the H2O binoculars, but not at the cost of weight: most H2O models weigh less than 28 oz.
