I record with AutoChart Live on my Helix 10 G2. I remove the card when finished with each session and copy the ACU files to a separate dated folder with the pool depth noted. I then import the ACU file into AutoChart Pro to correct any errors, after which I create a map and then update the LakeMaster card. Following which I get the message: "Your LakeMaster SD card was successfully updated with the new chart data. Would you like to change background map display to the custom LakeMaster map?"
This procedure has been working for me until lately when I have been loosing all data points from the previous session when I place the card back in the Helix. All data points still show in AutoChart Pro. I do notice that the ACU file on the Zero Lines card has not been changed. I do see that many of the ACNAMI/AC/LkMaster bin files have been changed. I thought the ACU files would also be changed.
Am I doing something wrong, should I be doing sonar recording and converting to ACD files in AC Pro instead of AC Live?
I read on another fishing site, "Turns out AutoChart Pro editing only applies to the creation of Lake Master maps which gets copied to the Zero Line SD card and will not apply the edits to the AutoChart maps that get created as you map on the water." "If you want to do edits to Autochart ACU files you created as you fish you will need to sit in your driveway, with the control head powered on and use the functions in the software to delete small bits of data piece by piece."
You Can see the Data Difference in the photos.
