Hi @odedezra -

I expect you’d run into issues just plugging them in and using without custom software, due to acoustic interference, and no coordination of the pulses…

You can see a discussion of this topic in this [thread](https://discuss.bluerobotics.com/t/suitability-of-ping-sonar-in-caves/11655/8), and this [one](https://discuss.bluerobotics.com/t/2-ping-sonars-on-one-rov/11958/2), and a previous answer to this question [here](https://discuss.bluerobotics.com/t/two-ping-sonars-integration-with-qgc/16382). The forum search tool can be quite powerful!
