Actually kosmo you have used the 360 Imaging much more than I have. I have not been out on the water with a production version 360 Imaging yet and I’m overdue!
I do know about the theory of operation though and suspect that the Di sonar works the same as if you were using the standard HDSi transducer.

As for screen snapshots: you can take these anytime just like always and the blue icon in the lower left indicates that the 360 Imaging transducer is being used as the sonar source for the Si/Di sonar.
