The Selftimer is a self service timing system for recreational race courses, speed climbing, carving courses and/or speed measurement. It can be operated with a coin collector or for free with just a start light. Further components of the system are a startgarte at the start, a photocell with reflector at the finish and a selftimer display board. The selftimer system can be extended by a second display showing the speed while at the same time the selftimer display shows the running and finish time.
