That LCX19 looks sweet and the 18 seems nice for money...
I'm reinvestigating all of this too but even though I'm trying to conserve realestate, I don't want all eggs in one basket.
I have a Furuno 6100 mono finder and a 1622 Radar that came with the boat and those will stay on for the foreseable future. But I'm tossed between getting the 1850D Chartplotter which I know is a great deal
or a different unit like the LCX18 sounder / plotter. Still haven't decided. Pros and Cons to all...
The Lowrance is nice because you throw a 2nd MMC chip in it and you can Xref your plotter tracks with your sounder info and replay them on ther PC. A big win-win if you want to research your findings that deeply
