I have 2 Humminbird Helix 12's and they have been running slow. When I tried to upload a card it said I did not have enough storage space so I had to figure out how to delete stuff that I really did not want to delete. I did a little research and found Humminbird PC. This allowed me to take the waypoints from both units and combine them to make cards for each lake. It was a little hard to figure out at first as there are no YouTube videos out there on this, so I made one. The use of Humminbird PC and Google Earth made this a easy project and also fun. Here is a video showing how to use it and how I did it. Something that I would recommend to all that have a Humminbird.

Nice post/Video!

Thank you Sir. I hope it helps people, which is why I put it out. I know it helped me. I am working on another with will be part 2 where you can plot the points on google earth pro, export them and pull them into Humminbird PC to put on your graph. You can look at years where the water is low and scout a new lake from your computer seeing everything that is showing out of the water. Thanks for the view and for the post!

Chris - thanks for sharing. This is something I've been thinking about figuring out for a while.

Thank you. I hope this helps. Has made a big difference for me for sure.
