Sonar is an acronym.
Sonars were used to detect any objects that got into the detection field of the sonar. By this, the military could detect enemy submarines etc., which they couldn't see normally because of the opacity and/or darkness of the water.
Sonar works by emitting sound waves from a transducer into the water. These sound waves travel through the water until they encounter an object, at which point they bounce back to the sonar device. By measuring the time it takes for the sound waves to return, the sonar device can calculate the distance to the object.
They used to travel by trains,bicycles and on foot on land and by ships.
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 is a way of finding things underwater, using the echo of sounds you emit. We have used it to find the shape of the lake/sea/ocean bottoms, to determine the depth of waters, to find fish, to locate ship wrecks, and to detect the presence of ships and especially submarines.

Because some sounds travel very well through water.
To map ocean depth using sonar, two key pieces of information needed are the time it takes for the sound waves to travel from the sonar device to the seafloor and back (ping time), and the speed of sound in water at different depths. By calculating the distance based on ping time and speed of sound, the ocean depth can be accurately mapped.
