rangefinder
Optical distance measurer
A rangefinder is a device that measures distance to a target.
Photographers use rangefinders to focus cameras; golfers use them to gauge distance to the pin; military personnel use them to aim weapons accurately.
The technology varies—optical, laser, or ultrasonic—but the purpose is always determining how far away something is: She checked her rangefinder before taking the shot.
