The Rangefinder binoculars usually have a scale to find ranges that allow an estimation of a particular distance from the object, especially if the height of the object is unknown or can be estimated.
For example, a common mariner at 7×50 scale of rangefinder binocular angled between a 5 mil mark, where 1 mil angle is marked between the 1m height of the object and at a 1000m distance. The distance is estimated by determining the distance from the object measured in meters, known height of the object and the object’s angular height in mil. It follows a certain formula and that is the distance from the object measured in meters divided by the object’s angular height in mil, and then multiply by 1000.
