You don't need the brain of a bat to do sonar. All you need is the right training. navy subs don't see where they are going under water. that job is left to the sonar operator. So the knowledge is there, but the device to do such with is not up to a good quality yet. Just like GPS it can put you on a pin point, but that kind of accuracy is reserved for military usage only. The devices for public are anywhere from 3 to 6 meters off.
