We have made the app as simple and clear to use as possible with large timing buttons and contrasting colours. You can keep your eyes at the finish line when using the RaceGorilla push button. You can be sure to have a 100% secure finish signal while timing your participants. The push button is a handheld baton, connected to the USB-C port of your smartphone.
The simple version of this tool is just the button with the USB-C connector to connect to your smartphone. In the special version, an external horn can be added as well. See and hear this video
The external horn, the same as used with the photocells, comes with a 5m cable.
The button uses the battery power of your smartphone, so you have to be aware of extra battery consumption. There are many different types of Y-splitter cables (available at regular computer shops) to connect a battery pack as well.
