SonarChart is an HD bathymetry map featuring extraordinary bottom contour detail for marine and lakes, excellent for increasing awareness of shallow waters and for locating fishing areas at any depth level.
Want better charts? Go boating!
SonarChart is constantly enhanced by sonar logs contributed by boaters such as you. Navionics accepts sonar logs recorded with the vast majority of sonar/plotter brands and mobile devices. These are integrated with existing data, updating SonarChart to reflect the ever-changing conditions of sea, lake and river bottoms.

Contribute sonar logs to enhance SonarChart. Use any of the options below.
Use the Boating app to make the most of the SonarChart Live. Just connect the device to your sonar/plotter, in either of the following ways. - Connect directly, if it has built-in Wi-Fi® connectivity. - Or, connect through a router with Wi-Fi. Sonar logs are automatically shared.
Wi-Fi is a registered trademark of the Wi-Fi Alliance.
Use a plotter with built-in Wi-Fi connectivity, and you can: - Create SonarChart Live right on the screen. - Record sonar logs on the plotter, then upload via Plotter Sync or click here. Logs recorded with older units (since 2003) that do not have Wi-Fi technology can be exported to a card (if required) and uploaded using a computer.
Lowrance, Simrad and B&G
SonarChart Live on the Boating app is the best way to automatically contribute sonar data from Lowrance, Simrad and B&G plotters. Models with built-in Wi-Fi, can connect directly to the mobile device. Other models that do not have Wi-Fi may connect to the Boating app using a router with compatible Wi-Fi, such as the Navico branded GoFree WIFI-1 Module.
Humminbird and Other plotters
Record your sonar logs to a blank memory card or on a Navionics card if space is available (1 hour of recording corresponds to about 1 GB). Then, upload them here through a computer. Alternatively, use SonarChart Live.
