*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.
All compasses we sell are MS models balanced for use in the southern hemisphere.
