Okay kiddo, have you ever seen a dolphin or a whale swimming in the ocean? They are really good at using a special sense called echolocation. That means they make sounds, and then listen for those sounds to bounce back to them, so they can figure out where things are in the water.
Scientists made a special machine called SONAR 2087 that works kind of like echolocation, but for big boats that need to find things underwater. The boat sends out sound waves that bounce off objects in the water, like rocks or other boats, and then the sound waves come back to the boat.
The SONAR 2087 machine listens really carefully to those sound waves when they come back, and it can tell how far away the objects are, and what they might look like. That way, the boat captain can avoid hitting things in the water, like rocks or other boats, and stay safe.
The SONAR 2087 machine is really important for submarines, which are boats that go underwater. They need to be able to see where they are going so they don't crash into things or get lost. SONAR 2087 helps submarines see underwater, just like echolocation helps dolphins and whales see underwater.
