*Graduations in Mils (Milliradians):
Mils compasses are divided into 6400 divisions rather than the standard 360 degrees. Mils compasses are largely used by the military for calculation of range and scale – for example two objects that appear to be 100mils apart and are 1000m away from the observer are around 100m apart on the ground.
