These sleek chartplotters offer big capability in a small package. Feature an ultra-bright 4" QVGA display and a built-in, satellite-enhanced worldwide basemap. Add even more mapping capabilities with the optional BlueChart g2 Vision card.
The worldwide basemap on all units can be enhanced with the optional BlueChart g2 Vision card, which provides high-resolution aerial reference photos for help navigating tricky harbors and channels — or locating spots like area marinas, fuel stops or restaurants.
The g2 Vision plug-in data card graphically depicts a true 3D "mariner's eye" topside view or "fish eye" underwater navigation perspective.
With fewer buttons to push and fewer operational steps to navigate, the simplified menu format makes it easy for you to see and select the data you want to access on-screen.
