I would start basic as most of us did, but having GPS with the FF is highly recommended. That being said, I would recommend starting off with either of these systems.

Humminbird:

I have had both of the units and they are very nice. I currently have the step up from the 386 and love it. I personally like Humminbird but there are some features that I liked that Lowrance had as well. Start small and work your way up.
