No, Liz. Compasses can shoot azimuth as well. Polar coordinates are a sighting to a known physical line, like a road or river. Or intersection. The back azimuth can then be used as a known line on a map, and a second sighting to another landmark will provide an intersection thing your position and thus giving you distance to any known map position.
Or you can set an azimuth on the compass dial and while keeping your north under the aImuth line allows you to navigate along the determined azimuth.
