Re: Sonar Viewer
Sonar does not give an "image". It merely tells you the distance (technically, the time it takes a signal to bounce back).
It won't help you "find" anything. It will merely tell you if anything is in front of the sonar. If you want to help determine distance to object the camera sees, that would work. In order to detect a boulder, the sonar will have to be mounted pretty low.
