Customize the RTS Window
The RTS Window plots the depth and intensity of a sonar return. It updates at the fastest rate possible for depth conditions and
shows only the returns from the bottom, structure, and fish that are within the transducer beam. When you use the cursor to review
sonar history, the sonar history will freeze, but the RTS Window will continue to display sonar returns in real time. See Review Sonar
History and Zoom In/Zoom Out.
