Downloaded Sonar Viewer Trial for now.

Opening Sonar files works fine, imaging is fantastic!

However when I try to open a .USR file it crashes the software.


Running windows 10, the .usr has about 1500 waypoints. I tried different versions of .usr v4, v5 etc.
No notification of a crash or error, the software just acts like I closed the software.
Is this a limit of using the trial version, maybe number of waypoints limited??

Which version USR is the file, do you know?
If this is a repeatable bug it would be very useful for us to take a look at the file. If you are willing to, please send the file to This email address is being protected from spambots. You need JavaScript enabled to view it. so that we can take a look. There is no limitation in the trial version of this sort. Do note that we will not share any of your data under any circumstances!

I will send you over the .usr to test, when I get to my other computer.

Thank you!!
