Distance measuring device

A distance measuring device is a tool used to determine how far something is from the observer or the device itself. It works by sending a signal—such as a laser beam or radio wave—to the target and measuring the time it takes for the signal to bounce back. Using this time, the device calculates the distance based on the speed of the signal. These devices are commonly used in surveying, construction, and navigation to obtain accurate measurements quickly and efficiently without needing physical contact or long manual calculations.
