Minute Markers
In order to maintain a visual presentation of your vessel’s previous movements, you
can draw these with a line. This line is drawn after the vessel symbol in the sonar
views, and visualizes your past movements. We refer to this line as the
History Line .
The
Minute Markers
function adds markers to the track line. These markers indicate
how far you have sailed in the last few minutes. The minute markers are shown as
small circles on the vessel’s track line.
Tip

Open the button to select a time period. The
Course Line

navigation sensors that are connected to the ST90 system.
