Sorry, I should clarify.
I understand 360 will have the longest range (distance from the boat), 2D is next, and then DI. If I understand 360 correctly, it's SI that spins in a constant circle, like a radar image.
As for quality of the returns/image. DI is superior to 2D for image clarity, detail of information. Will the 360 give better detail than DI, does 360 fall between DI and 2D, or does its level of detail fall below that of 2D?
