Sonar is the generic name of the technology that is used to locate objects underwater. Sonar systems are of two basic types - active and passive. In active sonar the system let's out a pulse of sound and then the operator listens for echoes. The passive sonar the operator listens to sounds emitted by the object one is trying to locate.
In the mountains i detect a rock with my SONAR.
The distance that sonar can detect objects underwater varies depending on factors like the power of the sonar system, water conditions, and the size of the object being detected. In general, sonar can detect objects up to several miles away when using higher power systems in optimal conditions.
Sonar can generally detect most things, and is commonly used in aviation An example of something that it cannot detect is the Stealth Fighter and the Stealth Bomber. They both have paint that helps deflect sonar rays, and the Fighter has very rigid edges that makes it almost undetectable.

A sub spotter is typically called a Submarine Sonar Technician or Sonar Operator. Their role is to detect and locate enemy submarines using sonar technology.
Sonar was used to detect and hunt submarines in WW2
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.

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.

Airplanes do not use sonar waves. Sonar is a technology primarily used underwater to detect objects or measure distances by emitting sound waves. Airplanes generally use radar technology to detect and track objects in the sky.
