That's not the way it works. No sonar, 2d, si, di is going to show a pic of discernable structure while sitting still. It's not like it's a camera image. It's a composite of sonar returns over time. So if you're sitting still it's just going to display the same return time after time and what you'll see is a streak of lines across the screen. You have to be moving to build the composite of returns over time which reveals structure.
