What's in a Zero Lines Card? 

Probably the best description of what Zero Lines and Auto Chart Live are all about. Thank you for posting! 👍 To be honest, Hummingbird making you buy their SD card is pretty cheesy. Any generic SD card should be simply formatted by the Auto Chart software.

Great break down of the directory structure on the Zero Lines Card, Thanks for this video.

Excellent video. Thanks for taking the time.

I am mapping a very big lake how can I get it all in one view, Autochart Standard is set at 7000X7000. Id like to be able to se the whole lake with all the files or at least add and build them.
