BlueChart g2 Vision
An optional, preprogrammed BlueChart g2 Vision data card allows you to get the most out of your chartplotter. 
In addition to detailed marine charting, BlueChart g2 Vision has the following features:
•  Mariner’s eye 3D (
)—provides a view from above and behind the boat for a three-dimensional 
navigation aid. The BlueChart g2 Vision Mariner’s Eye 3D is more detailed than the pre-loaded data.
•  Fish eye 3D (
)—provides an underwater, three-dimensional view that visually represents the 
sea floor according to the information on the chart.
•  Fishing Charts (
)—shows the chart with enhanced bottom contours and without navigational data. 
This chart works well for offshore deep-sea fishing.
•  High Resolution Satellite Imagery (
)—provides high-resolution satellite images for a realistic 
view of the land and water on the Navigation chart.
•  Aerial Photos (
)—shows marinas and other navigationally significant aerial photos to help you 
visualize your surroundings.
•  Detailed Roads and PoI data (
)—shows roads, restaurants, and other points of interest (POIs) 
along the shore.
•  Auto Guidance (
)—uses specified safe depth, safe height, and chart data to determine the best 
course to your destination.
