Exceptions
Notable exceptions to the above control point features occur in several orienteering sports.
- In amateur radio direction finding, the competitor uses a hand-held receiver to locate radio beacons at up to five control points that are not marked on the map. The Start, Finish, and optional drinking water stations are marked.
- In trail orienteering, the control point is marked on the map and up to five control kites are placed in that vicinity. The kites do not have a control code. From an observation point the competitor records which is the correct kite. In elite competitions, "none" is a valid answer.
- In NACMO (North American) style mounted orienteering and fox Oring only the general vicinity of the control point is marked on the map. In both sports the first objective is to navigate to the vicinity of the control point. Once there, the subsequent objectives are to find clues and take bearings, triangulate the location of the control point, then go directly to the control point. In mounted orienteering, once in the vicinity the competitor searches for clues (called landmarks) on a description sheet. The description sheet gives bearings from each clue to the control point. In fox Oring, once in the vicinity the competitor searches for a low power beacon at the control point.
- In TREC (European) style mounted orienteering, which permits no route choice, there are no control points for competitors but officials observe the competitors at specific points on the prescribed course.

Famous quotes containing the word exceptions:
“For true poetry, complete poetry, consists in the harmony of contraries. Hence, it is time to say aloud—and it is here above all that exceptions prove the rule—that everything that exists in nature exists in art.”
—Victor Hugo (1802–1885)
