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.
