Sonar or echolocation explained

Echolocation is a remarkable ability to use reflections of a signal to understand your environment. Dolphins, for example, can scan their environment using echolocation to catch food. And ships use sonar, a form of echolocation, to survey the depth of water around them.

I wish I could echolocate. Then I wouldn’t need the one eye trick.
