oGo is a punching start interval timer for orienteering. It works like a set of traffic lights.
Green: A runner may start when their course is showing a green “runner”.
Red: As a competitor starts the starter presses the course’s start button and the “runner” figure changes to a red “standing” figure. The next competitor must wait as oGo counts down to the next start.
Amber: Four seconds before the countdown ends the “standing” figure changes to an amber “get-ready” figure and a “beep-beep…” alert starts.
Green: When the countdown reaches zero the green “runner” returns and the next competitor may start immediately or any time after that.
Each course may be configured with its own name, start interval and start button colour. oGo can time starts for up to eight courses per event and store configurations for four events. oGo also keeps a count of the number of starts.
