Auto Guidance Technology

Whether you are fishing or cruising, select a spot, and get a route showing you the general path and nearby obstructions at a safe depth¹.

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.

Detailed Contours

BlueChart g3 charts feature 1’ contours that provide a more accurate depiction of bottom structure for improved fishing charts and enhanced detail in swamps, canals and port plans.

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.

NOAA Raster Cartography

For those who appreciate the familiar look of paper charts, raster cartography² of NOAA-surveyed areas can be downloaded for free via the ActiveCaptain® app to display on your chartplotter, including individual points of interest labeled with corresponding longitude and latitude information.

¹Auto Guidance is for planning purposes only and does not replace safe navigation practices. Auto Guidance is not included in preloaded BlueChart g3 for ECHOMAP™ Plus series chartplotters
²Raster cartography cannot be viewed on echoMAP CHIRP and ECHOMAP Plus combos but can be viewed on mobile devices via the ActiveCaptain mobile app
