Range Rings
You can turn on/off range rings from the chart settings menu.
The range rings can be used to show the distance from your vessel to other chart objects. The range scale is set automatically by the system to suit the chart scale.
Heading and Course extension
The length of the extension lines are either set as a fixed distance, or to indicate the distance the vessel will move in the selected time period.
Vessel heading extension is aligned with direction the vessel’s bow is pointing. COG extension points the direction the vessel is moving. If there is no heading sensor, heading will default to the COG value.
