Taking this unit out for its maiden voyage in the morning. I've read through the manual 4 times hoping some of this stuff would sink in. If anybody has had one on the water did the 455 or 800 KHZ DI work better for you and how about the 455 or 200 KHZ traditional sonar? I would think the narrower and sharper 800 on the DI would be better for the relatively shallow waters of the middle Hooch and maybe the wider 2D?
