Auto Chart, Auto Chart Pro & Auto Chart Live Information Resource

skigill, Yes Onix has autochart built in and you don't need the zerolines sd card. However, that is only good for 8 hrs of data. Beyond that, you start losing data. So, for most people, they're going to want a zerolines sd card to store more map data onto.

Bob B, ONIX can store up to 8 hours of AutoChart Live data on-board. You will need a ZeroLines SD card to store and display more data than that. You can return to a lake over and over again to add data, and the map will reprocess to accommodate old and new data together without any problems.

Thanks CamoHunter ...... I was wondering if you could move that onboard data to an SD card .....or does it only exist on the unit. I understand if you recorded to a zero line card initially, but didn't know if you could move it later.

You can move that onboard data to an SD card.

From what I gather on page 24 here: http://www.humminbird.com/WorkArea/D...t.aspx?id=6487
It sounds like you can save the actual map that you create from live data. But I'm not sure what happens to the data that was used to create that map image, if you don't save it (the track files/sonar recordings).
Here's what I believe ONIX is actually doing, based on my experience with the AutoChart PC program. Onix is taking your lat,long,depth points and processing them into a map on-the-fly. Inside the AC folder, it is storing and updating a map 'image' from your collected data. But, I don't know what it is doing with the actual data (the tracks/sonar recordings). I don't know if it stores those temporarily for a while, and deletes them eventually, or what happens with that.

Personally, I'd be saving ALL of my Humminbird Tracks and Sonar Recordings, and keeping them well organized on my computer.
I don't own an ONIX, and do all my AutoChart processing through the PC software program. However, even if I did have an ONIX unit, I would still want to save all those track files and sonar recordings. That way, if things go haywire down the road with the map you've created on the fly with your ONIX, you could still process all those data files with the PC program.
