A laser rangefinder is a precision measuring device that uses laser technology to determine the distance between the device and a target object. By emitting a laser beam and measuring the time it takes for the light to return after reflecting off the target, it provides highly accurate distance readings in various environments. Many laser rangefinders come equipped with additional features such as angle measurement, built-in compasses, and display screens for ease of use. They are commonly used in applications such as surveying, hunting, construction, and outdoor activities, making them essential tools for accurate distance measurement.
