Fish finder question
This, I'm sure, will sound like a dumb question to some of you but I have to ask. I have a Hummingbird Helix 5 fish finder. My question is this...when a fish symbol comes up on the screen is that really a fish? The reason I ask is that when I'm watching videos or reading fishing articles about fish finders it appears that fish detected on a finder screen is just a solid color, not the little fish symbol. Why is that?
