Interpretation of echo returns takes a bit of experience, and you really need to read the manual. The "cone" tells you that something (fish or object) is below. but exactly where and what takes a lot of experience. In the case of a Hummingbird 950c series is has a dual frequency DF/fish finder. The orange returns (fish) are from the 200kHz "narrow beam cone' and the Blue fish are from the 83kHz beam. In general the more dense a return the redder the icon. But you really need to read this whole section of your manual..... You can go to the link below, to download Hummingbird manuals. Once I remember looking at a piling laying on the bottom for some time before I figured out what it was. I've also spotted a school of small fish, that looked like a really bad return of scattered noise. You just have to work at it. Good luck!
