Zero Line card will allow you to store a bunch of "contouring" ... which raises my questions

1) I will have 3 units hooked together through a 5 port box .. will they share mapping??

2) If they don't share then can I pull the card and save it to both machines? or just look at it on the other machine??

3) Does Humminbird PC have a way to store the contouring .... got to have a way to back it up in case I lose it accidentally!!!!

4) If Humminbird PC doesn't have a way to backup then what would be the best way to "save" the "contouring"??


Any random thoughts youll have on managing the collected contouring will be appreciated!!!
