Currently, I am running (2) Lowrance HDS 12's at the console and (1) HDS 12 at the bow. I am purchasing (2) Humminbird Helix 9 part #409920-1 to run the LakeMaster+ card because the mapping is far superior than the Navionics Platinum that I have on my Lowrance units. Since I have always ran Lowrance, I have a few questions:
1. Can I run a network cable and connect the two Helix 9's together and share waypoints?
2. Can I share the same LakeMaster card between the two units or will I need a card in each unit?
Thanks for the help!!
