Use the Hammer Sonar to Reveal Rare Minerals for Shinsekai: Into the Depths

Use the Hammer Sonar to Reveal Rare Minerals

Early in Shinsekai: Into the Depths you will learn the hammer sonar technique which is invaluable when exploring the underwater world. When you trigger the hammer sonar technique by slamming down on the sea floor you will emit a sonar scan which will reveal nearby rare minerals and also mark noteworthy things on your map. Later in the game when you gain access to a submarine you will be able to use the hammer sonar technique to scout your surroundings a lot quicker.
