What is a common type of electronic distance measurement instrument?

The common type of electronic distance measurement instrument identified here is a laser light. Laser distance measuring tools utilize a laser beam to accurately measure distances by calculating the time it takes for the light to travel to a target and back. This method is not only precise but also allows for quick measurements over long distances, making it a versatile and widely used tool in construction and surveying.

In contrast, while GPS devices can determine positions and distances based on satellite signals, they are typically used for geographical positioning rather than precise distance measurement on-site. Optical theodolites are essential for measuring angles in horizontal and vertical planes, but they do not specifically measure linear distances electronically. Ultrasonic range finders use sound waves to measure distance, but their accuracy can be less compared to laser technology and they are not as commonly utilized in professional settings for distance measurement. Thus, laser light is recognized as a common and reliable choice among electronic distance measurement instruments.
