Dead reckoning which is usually hit or miss on the surface but better than nothing. Probably worse under the water. It's why all these subs that dive to Titanic have to drop down until they hit the floor and then swim around until they find a landmark that points to the ship. They only have a rough idea of where they are when they get to the bottom.
