Using Mariner’s Eye 3D
A BlueChart g2 Vision SD card offers Mariner’s Eye 3D, which provides a detailed,
three-dimensional 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 when trying to identify entry and exit routes in unfamiliar harbors or anchorages.
