The Data Key is very useful for storing the data measured by the MyChron4 and downloading it to a PC for analysis using the powerful RaceStudio2 analysis software.
Thanks to its 32MB of memory, it can record a large number of test sessions.

Thanks to the Data Key you no longer need to wait to recover your data: simply disconnect it from the MyChron4 and insert it into the USB port of your PC like any memory card.

There is no need to stop the session (race or tests) if another Data Key is immediately connected to the MyChron4 .
