I'm about to spring for the Humminbird Helix 7 si. I'm curious how often you all are using the SI to find fish as opposed to finding structure. I see a lot of examples of images of fantastic structure shown on SI, but I often don't see any fish and I feel I know what I'm looking for in terms of the light colored slivers though they are pretty hard to spot sometimes.

I figure if I see good structure I'm gonna fish it for a bit regardless of whether I see fish.
