The number shown on the chronometer are joy and sorrow for each kartist, the difference in between a good performance or frustration of could have done things better. Chronometers listed on our store are for all budgets and not for this less reliable.
Basically the difference consists on the instrument functions, from the one that provides the lap times up to 4 pilots at the same
time, such as UNIPRO and ALFANO, to the cheapest onesconcerning the single pilot, to the ones that give you the chance to download data on you own PC. Anyhow Superkart gives to all the possibility to get those essentials instruments for the track.
