AMB transponders being used for road course event

[Bad94]

So how will the scoring work for the road course portion. Is everyone that wants to compete expected to shell out another $400 so we can be timed now? I'm just wondering because when we all signed up it just said to click the appropriate box if we needed a transponder. I love racing with everyone but with the cost of events rising and with the groups starting to ask for cages/harnesses, I wont last long. Most of us have families to support and this is just for fun. Were not professionals.
Don't take this as a rant. I'm just trying to figure out whats going on.
Thanks

As for my understanding there will be a few transponder that will go from car to car in the car.



Im with you as far as cost, but the way i look at it, buy it now and then its MINE.
