Cpt. Paul - I'm sorry as I'm sure this question has probably been asked before but I couldn't find a direct response. Several years ago I purchased your Fishing Edge Waypoints for Calcasieu Lake for a Lowrance GPS unit that I had in a previous boat. I now have a Hummingbird Helix unit. Is there a way for me to use the same card or convert the format to use in my Humminbird unit or do I need to re-purchase the waypoints for use in a Hummingbird? Thanks.
