The Bushnell 7×50 Marine Binocular is a standard equipment item for boaters, sailors, and other water enthusiasts.  It provides clear images in even the most foul weather conditions from fog, rain, and ice, and can handle the hazards of salt water exposure.  This hermetically-sealed and nitrogen-purged unit gives reliable waterproof and fogproof performance, and even floats in sea water.  This ‘standard’ model (without compass) has a 7.2° viewing angle, which is very good for a 7×50 porro prism unit.
