Do I have to use GoChips at my race

Zone4 Timing is designed to work with a variety of inputs including tablet entry, Summits SRT timers, RapidCam, GoChip, and manual entry. Depending on the size and complexity of your race, different devices can be used. A small club time trial can easily be timed using the Zone4 android app, and ski races will definitely benefit from using Summit SRT timers. GoChip will make any race easier and it is a key component in most races, but it isn’t required to use Zone4 Timing.
