Seems to me that either option of the dedicated Di (using the Di transducer or the rotated si) both produce a better image than the Di from si..the 360 seems to complement the Di.what Im saying is if your one of thoughs Di freaks than i believe the 360 would be beneficial by giving you the option to see and fish structure before running over it using the Di with its limited front to back coverage.i still prefer the 2d over the Di but i can see were the 360/Di could be used. Rickie, i wondering what would happen if i used the rotated si transducer on my 597?
