Experience unparalleled coverage and brilliant detail when you’re on the water with charts that feature integrated Navionics® data, Auto Guidance technology¹ and more.

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.
