SonarChart
The system supports the Navionics SonarChart feature.
SonarChart displays a bathymetry map showing high resolution contour detail and standard
navigational data.
SonarChart Live
SonarChart Live is a real-time feature where the device creates an overlay of depth contours
based on your own live sonar soundings.
When you select SonarChart Live overlay the menu expands to display SonarChart Live
options.
Transparency
The SonarChart Live overlay is drawn on top of other chart data. The chart data is completely
covered at minimum transparency. Adjust the transparency to allow the chart details to be
seen.
Minimum depth
Adjusts what SonarChart Live rendering treats as the safety depth. This affects the coloring of
the SonarChart Live area. As the vessel approaches the safety depth, the SonarChart Live area
will gradually change from a simple grey/white to red.
