I am looking at humminbird pc and putting waypoints. How do I make a folder for different lakes and keep them separate? Like wayponts for Grenada and then in another folder waypoints for Enid? And also Am I able to put the waypoints on a sd card and put that in my graph and not officially upload them to my graphs memory? Like Have a card that is grenada waypoints only and a card the is enid waypoints only and I just keep em all in my boat for which ever lake I am on? Im working with the helix 9.
