AV Assistant is an 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. For reference use, Nearest Light, also in the App Store, is the better choice. AV Assistant is capable of making reports to the U.S. Coast Guard regarding discrepancies in aids to navigation and is primarily intended for USCG and USCG Auxiliary use. Refer to the website (url in Settings|Reference) for additional information. Warning: AV Assistant, which provides Light List data, is not intended to be used in place of charts or Coast Pilots. Charts should be consulted for the location of all aids to navigation. It may be dangerous to use aids to navigation without reference to charts.
