it has a magnetized dial instead of a plain needle. The dial is the one marked with the directions while the face is marked with numbers used for determining more precise directions. It has a lensatic card attached to it. This allows users to read the compass without needing to glance down and look at the compass’ face directly. A protractor is necessary for it to be used with a map.

The circumference of the compass face is divided into 6400 units. One unit is actually 1 meter of separation at a distance of 1,000 meters. One mil is also 1 yard at 1000 yards. This is the military (or mil) system.

 

They are more complex, and require special training above and beyond the normal compass.

Subject: [MSAR] compass question

I was reading the New Mexico MSAR study guide and it states that military or lensatic compasses are not acceptable for their gear list.  May I ask why?  Does it have to do with how the compasses react with the terrain there?
