The Cuda 240 has three major Sonar display options. They are the Full Sonar Chart, Split Zoom Sonar Chart and Digital Data.
You access the various display modes by pressing the PAGES key. Press → to SONAR↑ or ↓ to desired pageENT.
The Full Sonar Chart is the main Sonar display option. This is a "cross- section" view of the water column beneath the boat. The chart moves across the screen, displaying sonar signal echoes that represent fish, structure and the bottom.
