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

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.

SCL History
Select to display previously recorded data on the chart overlay.
Ú Note:
SonarChart live does not record while SCL history files are
being viewed.
SC Density

contours.

Navionics Dynamic tides and current icons
Shows tides and currents with a gauge and an arrow instead of the
diamond icons used for static tides and current information.
The tide and current data available in Navionics charts are related to
a specific date and time. The system animates the arrows and/or
gauges to show the tides and currents evolution over time.
