@wolfmountain97 The 2021 Deep Vision price list that I have says that the BlueROV2 complete package is €3,677 (google says that it converts to $4,166.96), but I don’t know if you could get the raw data or if it’s just for imaging. I suspect that it’s just for imaging. I agree that a product specifically designed for a AUV might be a better option as long as it can handle your depth requirements, since it’s more likely to be designed to support autonomous control software. A plus for that Deep Vision BlueROV2 unit (if it supports what you want) is that it’s designed for the BlueROV2 so the installation should be very easy.
I think it uses the same transducers of their towfish that I bought a few months ago: DeepVision DE680D sidescan "review"/experiences
I haven’t seen a way to get access to the raw data on mine, but I also haven’t looked for a way since it’s not something that I’m interested in.
They made some official video showing off the BlueROV2 sonar:
