in-car Timing System question
Hi BB'ers...
In October I came out to the track and saw some in-car timing systems...
what were they? I need some details so I can make sure Santa knows
exactly what to get. From what I gather, there is some transmitter box
that is set trackside on some frequency and then the in-car device is set
to match that frequency and receive the blip to do a timestamp???
Details? websites? recommendations? caveats?
Thanks!
