In the field of measurement, both rangefinders and laser rangefinders are commonly used tools, but there are some significant differences in their principles, accuracy and applications.

Distance meters mainly rely on principles such as sound waves, ultrasonic waves, and electromagnetic waves to measure distance. It uses the speed and time these waves travel through a medium to calculate distance. The laser rangefinder uses a laser beam as the measurement medium, and calculates the distance between the target object and the rangefinder by measuring the time difference from emission to reception of the laser beam, combined with the speed of light.

Laser rangefinders far exceed traditional rangefinders in accuracy. The measurement accuracy of traditional rangefinders is usually between 5 and 10 millimeters, while the measurement accuracy of laser rangefinders can reach within 1 millimeter. This high-precision measurement capability makes the laser rangefinder an irreplaceable advantage in the field of high-precision measurement.

Due to the limitations of its measurement principle, distance meters are usually suitable for distance measurement in fields such as electricity, water conservancy, communications, and the environment. Laser rangefinders are widely used in construction, aerospace, automobiles, military and other fields due to their high precision, high speed and non-contact measurement characteristics. Especially in situations where high-precision measurement is required, such as driverless car navigation, terrain surveying, etc., laser rangefinders play an indispensable role.

There are obvious differences between rangefinders and laser rangefinders in principle, accuracy and application fields. Therefore, in practical applications, we can choose appropriate measurement tools according to specific needs.
