Sprint Heat Timing Devices

What you select for timing devices will depend on the level of race you’re doing and whether the heats are timed or untimed. The timing device setup for heats happens on the Courses tab of your heats race.

Untimed Heats 

For untimed heats there is no need to assign timing devices however assigning an android phone to the start might still be helpful so that you know when groups are on course. This is especially true when you do not have a good view of the race start.

Getting the finish order correct in untimed heats is the most important. What you choose to use to ensure the correct finish order is given will depend on what is available however here are a few options.

  • Spotters: These are volunteers who are assigned to looking at the finish order as racers cross the line and relaying that info to the timing hut. Generally at least two spotters should be used.
  • Video Camera set up at the finish: When a photofinish camera is unavailable setting up a camera at the finish can be a good alternative. This should be used in conjunction with spotters to determine close finishes since playing back video id time consuming.
  • Photofinish Camera: When available a photofinish camera hooked up to a computer in the timing hut is the ideal solution.  

Timed Heats 

All tier 1 (FIS sanctioned) races must have times heats. Timing devices for tier 1 events are regulated by FIS. For these events you would use:


  • Start Horn hooked up to a summit.
  • Android Phone or second Summit as backup. These could be used as primary for non FIS races.


  • Photofinish camera as primary timing devices. 
  • Timing chips, photocell or spotters as backup. A combination of several can also be used.
  • A mix of timing chips and spotters could be used for non FIS events.
