Charts and 3D Chart Views
Showing AIS Vessels on a Chart or on a 3D Chart View
AIS requires the use of an external AIS device and active transponder signals from other vessels.
You can congure how other vessels appear on a chart or on a 3D chart view. The display range congured
for one chart or one 3D chart view is applied only to that chart or to that 3D chart view. The details, projected
heading, and trails settings congured for one chart or one 3D chart view are applied to all charts and to all 3D
chart views.
: The Mariner’s Eye 3D chart is available if you use a BlueChart g2 Vision SD card. The Fishing chart
is available if you use a BlueChart g2 Vision SD card or a BlueChart g2 SD card, or if your built-in map
supports Fishing charts.
