Contacted Humminbird customer service and explain that my helix depth had jumped around and never read the right depth since it was new and when I downloaded the software to fix it it locked up in shut down. I was told since it was 2 years old and that downloading soft ware couldn't lock up a sonar that it had to be some other issue and it would cost me $257 for a service charge. Hope others don't have these issues with there software.
This might be a good time to go to livescope lol
