SonarChart Live allows you to create an HD bathymetry map that displays on your device in real-time while navigating. The new chart appears as an additional layer over either Nautical Chart or SonarChart. You can use your plotter/sounder or mobile device to create your personal HD bathymetry map in real-time with SonarChart Live. SonarChart Live is an excellent way to monitor the improvements your survey will bring to the SonarChart because contours are instantly seen while you're collecting sonar logs. See webinar.
