Sonar is used to gain information about objects underwater which you can't see because of the darkness and/or opacity of the water.
A submarine uses sonar, like a bat uses echolocation to see.
A sonar uses one device and a sea beam uses a dozen sonar devices.

Sonar uses sound waves to detect objects underwater, while radar uses radio waves to detect objects in the air or on the ground. Sonar is typically used in marine environments, while radar is commonly used in aviation and meteorology.
Sonar uses electricity, so the source of energy is either a generator or a battery.

Sonar
A bat uses "sonar" because of it's lack of sight. A bat's "sonar" is the closest thing it has to sight, as it can identify individual objects with it.
Sonar (Sound Navigation and Ranging) is the system that uses the reflection of underwater sound waves to detect objects. This technology is commonly used in naval navigation, fishing, and underwater mapping.
