NavLink Charting
NavLink utilises the latest S57 based NOAA digital mapping and features automatic free updates for 1 year. With vector mapping, you can manage your layers of data to de-clutter the screen or maximise information. NavLink supports all key charting feature such as buoys, lights, bridges, depth contours, spot depths, depth contours, anchorage and military areas, weather buoys

NavLink is compatible with all Digital Yacht's wireless NMEA devices such as the iAIS, WLN10, WLN10HS, NavLink, iNavHub and PilotLink that stream wireless AIS data to your Apple device

Please note: Continued use of GPS running in the background can dramatically decrease battery life
