Down Imaging:
Humminbird has taken the side imaging in a new direction...straight down.  Now you can see what is happening directly below your boat. 

• Down Imaging "snapshots" are created with high-frequency sound waves emitted in razor thin slices.
• Sonar returns from these waves create an instant "snapshot" below the boat.
• Narrow Mode analyzes the returns to verify the position of the echoes to ensure Down Imaging only shows you structure and activity beneath you, and not off to one side or another.
• DOWN IMAGING / 2D SONAR - This view provides complete understanding of what, exactly, is going on below your boat. Quickly identify structure with Down Imaging™, while using 2D to locate and target fish. Together, they take the guesswork out of sonar fishfinding.
• DOWN IMAGING / SIDE IMAGING SONAR - Get a complete 180° view. Down Imaging provides picture-like views directly below the boat, while Side Imaging shows structure out to 240 feet on either side of your boat. It's two detailed images unlike anything you've ever seen.
• DOWN IMAGING / SIDE IMAGING SONAR / 2D SONAR - Don't miss a thing with these three Humminbird technologies working together. Use traditional 2D and Down Imaging together for a straight down view, while Side Imaging reaches out to both sides.
