A b s t r a c t An orienteering compass comprises a compass hous- ing with a moveable north indicator and a base plate having a fixed course line. To enable directions to be extracted and checked in a simple fashion, and to enable a map to be read more positively when orienteering, the compass housing is non-rotatably connected to the base plate and the base plate together with the compass hous- ing is arranged so that it can be pressed against and readily held on a map with the course line in the desired direction. Preferably, the course line extends in front of the compass housing and coincides with a longitudinally extending edge of the base plate.
