Add one?  I am not sure.  I am running two 93sv units, networked with the UHD package.  I originally created my own network hub for a bout $30 which worked very well.  If you buy the new echo map ultra units, you can use the $500 livescope transducer without the black box.  That unit will also network with other echomap units and share the livescope.

 

I run run my unit on the trolling motor.  It works well.  I find fish, then anchor.  That way I can use my livescope and not worry about drifting.  I can position my livescope in a way that a person fishing on the back can see my console unit and get on the action as well.
