Bushnell H2O Xtreme 10x42 compact waterproof binoculars with fully multi-coated waterproof lens for hunting and boating are an upgrade to the standard H2O binocular with increased performance from fully multi-coated lenses and a rugged rubber design with full IPX7 waterproofing. Specifically designed for wet conditions, these waterproof and anti-fog binoculars are O-ring sealed, which means they can withstand being dropped in standing water. Twist-up eyecups facilitate fast viewing and allow the binoculars to be adjusted comfortably for people wearing glasses.
