Classic ARDF is typically held in forests and natural terrain. Competitors search for a set number of hidden transmitters (foxes) spread over a large area. Courses emphasize route choice, endurance, and navigation accuracy. Each fox transmits in sequence, allowing athletes to take bearings and plan an efficient order to visit them before returning to the finish.
Sprint ARDF uses a compact arena with short legs between transmitters to test agility and quick decision making. With shorter transmit cycles, rapid signal identification and precise navigation are crucial. Sprint events are spectator-friendly and ideal for introducing new participants to ARDF.
FoxOring combines orienteering precision with radio direction-finding. Competitors navigate to small circles on the map, where a very low-power transmitter can be heard only when very close. Success depends on accurate map reading, fine navigation, and careful listening to pinpoint the fox location.
