I am getting ready to buy all the graphs for my next boat. I am going to run a 12 touch gen 3 and an HDS 8 on the dash and a 9 touch gen 3 on the bow. I have and like my Navionics card for Sakakawea, but is there anything new out there. I would like a second card but if there isn't anything else that is better then I will just keep running this one. This will be the first time I have everything networked together so maybe a second card isn't needed. New adventure for me with the networking thing.
