I want to link my two Garmin units together. Both are EchoMap Plus 9", one is a 93sv other is a 94sv. I want to run one transducer only if possible. Do I only need a network cable? https://www.basspro.com/shop/en/garmin-marine-network-cable?rrec=true 

 

or do I need a hub or something?

Just a network cable should be all you need

He is correct, you won't need the hub until you add panoptix ?

not sure if I love or hate the sound of that, I already have 4x 9" gamins in a 14' boat

The Ultra units have two ethernet connections, so you can do panoptix and network with one other Plus or Ultra unit, and not have to have the network hub, once you go to a third unit, you need the hub.  Plus to plus will work but no panoptix.  Plus to panoptix will work.

 

Two ultra units would give you panoptix, network between the ultra units, and a spare ethernet jack to hook to another unit.  Dont quote me on that though.

 

My older CV transducer on the transom, from the 73plus on the console will not work when plugged into the Ultra, due to the software needed to stitch together the side image from the CV transducers.  My 73 and ultra are networked, but I forget if I can view the CV (transom) from the ultra.  I think I can though.

 

Very confusing, I know.

 

 

Don't mean to get off topic but how do you like the 93sv?? Thinking about buying one but don't know much about them quite honestly. I was planning on the striker 9sv but it's discontinued plus the 93sv is the same price + touch screen and loaded maps?

I have a 93plus unit running the CV transducer and it is awesome.  The menus are intuitive and the maps are great for not having to buy a chip.  The contour mapping is great for the areas that don't have maps or you want more detail.  I can't speak for image quality between brands as my previous FF was an Lowrance x-4 and it was a budget model for its previous owner when I got it 6 years ago, but the images I've gotten on screen definitely help me distinguish bottom types and locate the things I thought I was feeling with my baits.

You also get the cables made to your length for much less with the same quality.  Shielded, grounded, cat7, network cable.
