Do you have any recommendations for importing large Humminbird sonar logs? I have files that exceed an hour in duration, amounting to over 2gb in file size. I'm able to import the file, but not able to see anything. Hovering the mouse over the map will reveal the track point my cursor is over, but I cannot see any other track points. I'm also not able to view the sonar in the Sonar Viewer. My computer specs should not be an issue (Intel Xeon E-2136 @ 3.3 GHz, 64 gb RAM, NVIDIA Quadro P2000). Any guidance would be greatly appreciated!

This sounds like a rendering issue more than an import issue, although I would not recommend using files as large as 2GB for a few reasons. Smaller files are generally easier and faster to handle, and you reduce the risk of losing data if a single file becomes corrupt when you are recording (it does happen occasionally).
Could you try disabling hardware graphics acceleration (global settings window), restarting ReefMaster and reloading the workspace to see if this makes any difference?
Have you had any issues viewing smaller files within RM?

Hi Matt, thanks for the quick reply.

I disabled hardware graphics acceleration, restarted, and now my data is viewable. Thanks for the recommendation.

Do you have a max sonar file size recommendation for working with data in RM?
Thanks!
