You can add one or more available sonar views to a custom combination screen (Customizing with Combination Pages). If more than one source of sonar data is available, you can show sonar screens using different sonar sources in separate windows of a custom combo screen.

If you have more than one source of sonar data available, you are prompted to select the source to use when creating a custom combo. After you create the combo, you can change the source used in a window of the combo screen later (Selecting a Sonar Source).
