Azimuth is the name of one of my favourite fetish pornstars.

to give you an exact heading. you could survey with it. but it would be a real shitty survey.

The scale is in degrees
And in Mils, military lensatic compass. Units used mostly by artillery.

The ring is illuminated for night use. And each click corresponds to 3 degrees.

The line on the lid and "sight" are for getting more accurate Azimuths, or aiming to walk long stretches.

military compass is made to be used with military maps. it's very awkward to use it with any other map. the angles are not in degrees but mils which is useful to call in an artillery strike not so useful to determine your heading.

it's not degrees scale it's a rough 5 degrees and 50 mils.
