Lowrance HDS 5x Gen2 | Fishfinder - LOWRANCE | Marine Electronics

Besides $150

I see one is a Chartplotter, and after reading this:

What is a Chartplotter and why do I need one?

I'd just assumed if a FF had GPS and a map card, it was a "chartplotter". So I guess that's incorrect?

Or the other (less expensive one) shown, doesn't have GPS? So I'm comparing apples to oranges?

Is the transducer not included? I'm corn-fused (in case it's not obvious, lol), and how would I know which transducer to choose?
