Summary
[edit]English: An orienteering control point flag, paper punch and electronic punch device (SportIdent) on an ARDF orienteering course. The grey box is a immediate results transmitter which reads the data about punches directly from the punch device and send them to the finish where can be used by reporter to announce preliminary results. The control transmitter (transmitting MOI --/---/..) and its antenna is located in an adjacent tree, about two meters above ground. The orienteers find the control point using their receiver (in fact the transmitted signal leads them to the antenna of the control transmitter), they find the control (the color of control flag is orange/white because this combination is not present in the forest), punch the card and the result transmitter sends information about the presence of each orienteer to the finish.
Español: Transmisor oculto en el bosque (encima, en un arbol), con otro transmisor para reportar cuando los competidores encontran cada transmisor. Utilizado en el deporte de orientación por radio.
