available on your preloaded maps, including buoys, lights,
cables, depth soundings, marinas, and tide stations, in an
overhead view.

boat (according to your course), and provides a visual navigation
aid.
• —displays two different zoom levels of
the Navigation chart at the same time.
Mariner’s Eye 3D charts and Fish Eye 3D charts are available
only if you use a BlueChart g2 Vision SD card. Fishing charts
are available if you use a BlueChart g2 Vision SD card or if your
built-in map supports Fishing charts.

bottom contours and without navigational data. This chart works
well for offshore deep-sea shing.

represents the sea oor according to the information on the chart.

the boat as a three-dimensional navigation aid. The BlueChart
g2 Vision Mariner’s Eye 3D is more detailed than the preloaded
data.
