SonarChart™ Live

Create your own maps

Watch new 0,5 m personal HD bathymetry maps develop in real time as your boat moves along the water! It appears as an additional layer over your map, while it also gets stored on your device for future use.

Map the uncharted!

SonarChart Live also makes it possible to create new maps of uncharted areas. If your favorite water body is missing from our maps, get on the water and benefit immediately from the results!

Want better charts? Go boating!

Depth data gathered during SonarChart Live can also be shared with Navionics to enhance SonarChart for all boaters. Navionics accepts sonar logs recorded with the vast majority of sonar/plotter brands and mobile devices.

See evidence of your survey

SonarChart Live is an excellent way to anticipate the improvements your survey will bring to SonarChart, because you can see new contours as they develop. The data you gather is checked along with other new sonar logs and Navionics data before being integrated, normally within about a week but may sometimes take longer based on data process variables.
