{% hint style="info" %}
We're going to talk about all the things that can go wrong with sonar systems, and at the end of this, you're going to wonder if there's a snowflake's chance in hell of getting your ROVL system working. Despite all the possible challenges, most ROVL systems work as expected right out of the box. The information in this section is included to help troubleshoot systems in the minority of cases where there are issues, and help you design more robust systems if you are trying something unique or an application we haven't foreseen.
