Using BlueChart g2 Vision

Optional BlueChart g2 Vision preprogrammed SD cards allow
you to get the most out of your unit. In addition to detailed marine
charting, BlueChart g2 Vision has the following features:
• Mariner's Eye 3D—a bird's eye view from above and behind the
boat, for a more visual navigation aid. The BlueChart g2 Vision
Mariner's Eye 3D is more detailed than the preloaded data.
• Fish Eye 3D—an underwater view that visually represents the
sea floor according to the chart's information.
• Fishing Charts—view the chart without navigational data,
leaving only the bottom contours and depth soundings. This
chart works best for offshore deep-sea fishing.
• High Resolution Satellite Imagery—high resolution satellite
images are provided for a realistic view of the land and water
on the navigation chart.
• Aerial Photos—view marinas and other navigationally
significant aerial photos to help you visualize your surroundings.
• Detailed Roads and POI data—view roads, restaurants, and
other points of interest (POIs) along the shore.
• Current Data—view current station information.
• Auto Guidance—automatic passage planning software that
helps you determine the best course to your destination.
