*Mils (Milliradians)

Mils compasses are divided into 6400 graduations rather than the standard 360 degrees.

Mils compasses are largely used by the military and army cadets for calculation of range and scale. For example, two objects that appear to be 100 mils apart and are 1000 metres away from the observer are around 100 metres apart on the ground.

All compasses we stock are MS (magnetic south) models balanced for use in the southern hemisphere.
