Binoculars

Enhanced visual observation and navigation on board ships with a pair or two of binoculars, including one's for night vision. They allow the crew to spot distant objects, vessels, navigational markers, and potential hazards more clearly, aiding in safe navigation, situational awareness, and maritime security.

Marine binoculars normally have a 7x magnification and 50mm objective lens diameter and more than 300 feet of field of view at 1000 yards.
