Chris,
Happy New Year and a belated Merry Xmas.
Just an advice – get a timing system which uses magnetic strip timing as most kart tracks would have this strip already in place. Shah Alam, Elite and Sepang all have this.
Unless u want to use the IR/beacon setup for some other things – the magnetic strip is best….nothing to leave on track, nothing to forget and hence you wun lose anything. Zero Maintenance too.
Btw, rpm is the other very important feature to have ( for tuning ) plus a water temp sensor too ( to monitor health of engine )….all features which the Alfano Pro has.
Happy Shopping.
