How many triggers do I need?

Understanding how many external triggers you need it's easy!

Open lap

If you're riding downhill or any kind of sport that occurs on an "open" track, you'll need TWO triggers. One to be placed on top (to start the timing) and one to be placed at the bottom (to stop the timing). In this case, please buy the bundle "Double".

Closed lap

If you're riding cross-country, moto or any kind of sport that occurs on an "closed" track, you'll need just  ONE trigger. One to be placed closed to the start/finish line. In this case, please buy the bundle "Single".
