A rangefinder is a device that measures distance from the observer to a target. ==Techniques== Some devices use active methods to measure (such as ultrasonic ranging module, laser rangefinder, radar distance measurement); others measure distance using trigonometry (stadiametric rangefinders and parallax, or coincidence, rangefinders). Older method...
