How can you put sonar on an ROV?

How can a commercial sonar system be interfaced with a computer controlling an ROV? Also, how could one build their own homemade sonar system?

I was wondering the same thing, I have been looking at fish finders to figure out if it would work. Right now I'm looking at the Hummingbird 596c HD DI. I'm Interested if we could modify the cable to get it to work.

 You could use a fish finder and extend the cable... Maybe program a phidgets board to run a digital line up to the surface...
