Nearest Light is a informational aid for U.S. waters that shows your location and details on all surrounding aids to navigation (buoys, lights, etc) within your Area of Interest. The app downloads the weekly U.S. Coast Guard Light List for your district, and then shows the aids within your Area of Interest and their details. Any applicable Local Notice for Mariners information is also shown with the light data. Refer to the User Manual (url in Settings) for additional information.
Districts: D1, D5, D7, D8, D8WR, D9, D11, D13, D14, D17
