Fish Finder help (hummingbird 160)

[jumpinjoemoreno]

So i got my FF set up over the weekend and went out to Glorietta bay yesterday, FF was tracking Depth and temp and drop offs pretty good, just wasnt picking up any fish. I realize this question can be contorted in many ways(duh dumbass there were no fish!) but as much as paddled around i had to have come across atleast one fish! What are come things i can try? I just need it to pick up fish then i will be set. Can anyone help me on this one? thanks. Joe
