I've never used structurescan, but I do occasionally use the side imaging feature on my humminbird. I've been using it for a couple years now and I have found a few reefs in big lake and sabine lake while using it. I will admit though, I don't aimlessly drive around with my side scan on and hope I find something. While in shallow water, I usually see something on the surface that draws my attention to check it out with side imaging. For instance, a slick. I'll see a slick in the middle of big lake, catch fish on it, then check out my side imaging and see if the fish are holding on a reef there or if they are just feeding on moving bait. If there is indeed a reef, I'm able to mark it in detail because of the accuracy that my side imaging affords me. Mostly, I've been able to dial in the reefs I already like to fish and now I understand them better by being able to see them in photo quality. Same goes for some of the deeper water spots I fish. I don't know how structure scan will work in shallow water, but I do like my side imaging. Do I absolutely need it? No. Am I glad I have it? Definitely. Do I use it? Occasionally...I find myself fishing in more new water now that I have it and I've learned a lot since I bought it. I know you're talking structurescan and my experience is only with sidescan, but they both do similar things. Just thought I would chip in my 2 cents
