available on your preloaded maps, including buoys, lights, cables,

your boat; for a visual navigation aid.

•  Fishing Chart—removes navigational data from the preloaded 

map, while leaving the bottom contours and depth soundings. 

(This is not available on the 430/430s/430x/430sx - all contour 

lines and depth soundings appear on the navigation chart.)

•  Fish Eye 3D—an underwater view that visually represents the 

sea floor or lake bottom according to the chart’s information.

(This is available for select lakes on 430/430s/430x/430sx 

units without an additional card.)

Use the navigation chart to plan your course, view map information, 

and as a navigational aid.

optional BlueChart g2 Vision preprogrammed SD card for your
