Hi Chris. Thanks for your response. Konus is actually an Italian company with a subsidiary in USA also. It is a lensatic type compass but has the azimuth markings of 0-360 degrees, as opposed to military markings. I believe it is a mountaineering, surveying, engineering type compass. The web site is
www.konus.com. I have asked for the instructions and see what they say. I have a good idea on how to use a compass generally but would like more detail on this model. Thanks for the input.
