This is a shot of both. Regular sonar on the right, DSI or the 455/800 picture on the left.
For saltwater you are better off not getting the DSI because its depth penetration isnt great. HDI units can do both DSI and regular. HDI units are good for saltwater, but I upgraded to HDS recently and it's much better.

From what I have read and from playing with some fish finders in the store.....normal 2D sonar is good at finding fish and DSI is good at showing you structure
