Orca Charts can be adjusted to behave the way you want them to do – from visual representation to how they behave when you move around in the charts.
To edit your chart settings, go open the Main Menu > Settings > Chart.
These are the elements available to you for tailoring the map:
Allow Map rotation - Allow map rotation or lock to north-up only.
Follow mode - Change how the Follow Me button behaves
Show navigation aim line - extends a navigation aim line along your current course or heading
Navigation aim line distance - If the aim line is enabled, you may select between showing a Fixed aim line or a Dynamic aim line. If you choose Dynamic, you may choose between 10 mins or 30 mins
Orientation and aim line direction - This option lets you choose how the orientation and the aim line direction are calculated, either your course derived from the GPS or the heading derived from your magnetic compass
Show breadcrumbs - Your location during the last 24 hours of activity is shown in the map as breadcrumbs.
Delete breadcrumbs - Press there to delete your breadcrumbs.
Show AIS targets - Enable to show AIS targets from your NMEA2000 AIS receiver and from the Orca online AIS network
Ignore own AIS - Enable to automatically identify and hide your AIS broadcast.
