Does anyone know how to take Lowrance Waypoints that I have on a spreadsheet and convert them to work with a Humminbird? I do not have any of the card reader type stuff at home and have no clue how that stuff works.

I have always just plugged them in manual. As big of a pain in the butt that it is thats what I have always done. But I can not fina anything on the net to help me out here?

Thanks Lee
