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?

I would be reluctant to put 2d in an image quality lineup with any of the imaging Sonar technologies ... 2d is a cartoon image representation of echo data and should be best versed against maybe 2d CHIRP for quality standings ...

In the imaging Sonar technologies, and only using the 1 criteria of image detail quality - I would rank as SI / then DI / then 360 ...
