hey anybody know much about commercial divers doin pipe inspection?? i use to do sewer and storm inspection. drove this little robot through the pipe that had a video camera, that looks pretty much exactly like the ones on divers helmets i noticed, and sat in front of a computer in the back of a truck and used a little joystick to control it. it was pretty much just like an rov with something similar to tank tracks on it and a thousand foot cable connected. anyways im startin dive school soon and i read somewhere about divers doin pipe inspections like a dollar a foot or somethin.
