How does pinger works?

Answer 1

A pinger is a device or tool used to send out audio signals, typically in the form of ultrasonic waves, to locate or communicate with objects underwater or in other environments. It emits sound waves that bounce off objects, and the time it takes for the echoes to return is measured to determine the object's distance or location. Pingers are commonly used in marine applications, such as locating underwater equipment or animals, and can also be utilized in various industrial and scientific fields. The technology relies on principles of sonar and acoustic signal processing.
