Setting the Safe-zone Collision Alarm
The safe-zone collision alarm is used only with AIS. The safe zone is used for collision avoidance, and can be
customized. All safe-zone collision alarm settings are applied to all charts, to all 3D chart views, to all radar
modes, and to the Radar Overlay.

A message banner appears and an alarm sounds when an AIS-activated vessel enters the safe-zone ring

Perspective 3D
Perspective 3D provides a view from above and behind the boat (according to your course) and provides a
visual navigation aid. This view is helpful when navigating tricky shoals, reefs, bridges, or channels, and is
benecial when trying to identify entry and exit routes in unfamiliar harbors or anchorages.
