BlueChart g3 coastal charts provide industry-leading coverage, clarity and detail with integrated Garmin and Navionics data. Also included is Auto Guidance¹ technology, which uses your desired depth and overhead clearance to calculate routes and provide a suggested path to follow — overlaid onto your chart. NOAA raster cartography is also available as a free downloadable feature via the ActiveCaptain app. It gives your chartplotter paper chartlike views of NOAA-surveyed areas in which individual points of interest are labeled with corresponding longitude and latitude information. Worldwide coverage is available by regions as accessory cards or via download; each region is sold separately.

Depth Range Shading
This feature displays high-resolution Depth Range Shading for up to 10 depth ranges so you can view your designated target depth.
BlueChart g3 features up to 1’ contours, which provide a more accurate depiction of the bottom structure for improved fishing charts and navigation in swamps, canals and marinas.
Shallow Water Shading
To aid in navigation, Shallow Water Shading allows map shading at a user-defined depth to give a clear picture of shallow waters to avoid.
