Using Mariner's Eye 3D When using a BlueChart g2 Vision SD card, you can view the Mariner's Eye 3D screen. The Mariner's Eye 3D screen is similar to the Mariner's Eye screen (page 10), but is much more detailed. This view is helpful when navigating tricky shoals, reefs, bridges, or channels, and is beneficial when trying to identify entry and exit routes in unfamiliar harbors or anchorages.
