When the wheel rolls between two points on the map, the ranging pointer will move with it. Then record the data according to the corresponding scale and multiple by proportionality coefficient. On this way, you can get the actual distance between two points which is more accurate than the straight distance measured by ruler. The map range finder is convenient and fast to measure mileage and distance, so it is specifically used to measure the actual distance of the bending routes on the map.
