I have an Eagle 320c on my jonboat. I really don't think you need anything more in the bow, unless you want GPS capability. As I understand it, that can be a critical thing to have in Fl. I've never fished there, but the way I understand Florida water is that the critical part is finding that sweet spot or the right weedbed where they are stacked up. If that is the case, I would rather have worse graphics and GPS capability than the other way around. I could be wrong. It has happened before.
