For those interested, probably the best written instruction on the subject is Bjorn Kjellstrom's Be Expert with Map and Compass . Still in print. Available in several languages. Kjellsrom was the recognized expert on the subject and largely responsible for bringing orienteering as a sport to North America.
As an aside, it has been a long time since I've actually shot and followed an azimuth. Rather, I simply use a compass to orient a map. Terrain association is the most important skill which is why I rarely use a compass and always use a map. That's why I'll use button compasses most often. I wear a Sun button on my watch strap and have another as a zipper pull on my raincoat. I'll refer to one of these to orient the map, then just use the map without referring to a compass.
