Alright, I'm going to buy a Lowrance HDS. Compact in size is good and probably won't be interested in anything above an HDS 7. I would like 2d, Down and Side scan. I don't need maps or Sirius radio. I do need the transducers. I have a LMS-520c and am also wondering if I can network the two. I'll most likely mount the units side by side so I might consider a unit without the 2d. Is there a "Plain Jane" package to be had while not purchasing things I'll never use?

I just need someone in the know to enlighten me as to what exactly it will take to create the unit I would like.
