Hi guys. I just bought a used Polar Craft 17 bass boat and I want to upgrade the electronics. I am leaning towards a Lowrance HDS-7 unit on the console and a X510c unit on the bow. This is my first actual bass boat so I have alot of questions. How do I link these? Will the 510 allow me to mark waypoints if it is linked? Are there better options for around the same money? Will the 510 work with to universal sonar on my Minn Kota? HELP PLEASE. Thank you.
