range finding
Gauging target distance
Range finding is determining the distance to a target or object.
The term applies to various methods and devices—optical rangefinders, laser systems, radar, or sonar—used in photography, surveying, golf, hunting, and military targeting.
The sniper's scope included range finding capabilities.
Also appears as a noun: a range finder is the device itself.
