Using Charts

Using Charts

Your unit has a basic worldwide imagery map. By purchasing an optional Blue Chart® g2 Vision™ preprogrammed SD card, you can view detailed information for your region, including:

•Navigation Chart—displays navigation data, including buoys, lights, cables, depth soundings, marinas, and tide stations in an overhead view.

•Mariner’s Eye and Mariner’s Eye 3D—displays a view from above and behind your boat for a visual navigation aid.

•Fishing Chart—removes navigational data from the chart and enhances bottom contours for depth recognition.

•Fish Eye 3D—an underwater view that visually represents the sea floor according to the information on the chart.

The unit automatically shows relevant navigational data when you select a navigation option.

Using the Navigation Chart

Use the Navigation Chart to plan your course, to view map information, and as a navigational aid.

To access the Navigation Chart, from the Home screen, select Charts > Navigation Chart.
