The Deep Sea Series is a marine treasure chest of marine binoculars designed specifically for the nautical world and boating enthusiasts. With 7x magnification (most popular size because of the steady image achievable under rough sea conditions) and exceptional optics, these binoculars provide clear views of marine observation from dusk till dawn. In addition, selected models are engineered with internal navigational features. Built to withstand rough nautical conditions, the Deep Sea series is truly a jewel on the ocean.
