15.5 Multiple sonar module support
Your multifunction display supports multiple active
sonar modules on the same network.
You can select which sonar channel you want to be
displayed. Only 1 channel can be displayed at a
time in a single Fishfinder application pane. Multiple
channels can be displayed at the same time using
custom splitscreen pages. Alternatively multiple
custom pages could be set up to suit individual
requirements.
