2. Set the Contour Offset
You can set Contour Offset to maintain a set distance from a contour line. Contour Offset is a distance setting only, and does not
measure water depth. Input the Contour Offset based on your knowledge of the water depth in your current area.
If you have an AutoChart ZeroLine Map Card, and want to navigate along a bank or shoreline, use Contour Offset to maintain a safe
distance from the shoreline.
Contour Offset can be adjusted while Follow the Contour navigation is in progress by selecting Contour Offset from the Go To menu.
