Every year, we have a group that goes to an Outpost in Canada. I use a Humminbird Helix5, which is great for mapping the lake with AutoChart. I have been trying to use AutoChart Pro to create 3D maps and such, but it is SO OLD that it is only usable for the basics. I tried to find this from the support pages, but I cannot find the definitive answer.

What minimum data types must I capture for ReefMaster? The Helix5 only has one microSD slot, and Humminbird limits it to a 32G SD card. So, space is limited, and capturing AutoChart and Sonar data may make things tight.

Thanks in advance
