Thank you for the response, but I wasn't confusing the RaceCeiver communication systems our kids use with transponders. The same company, RaceCeiver, also makes transponder systems (http://www.raceceiver.com/p~28.php?c=11
). Here in FL, one track uses them and the other uses the AMB system. My question is whether or not there is a transponder that would work on both systems. It wouldn't be worth buying a personal transponder if I still had to rent one at half of the events we planned to go to.
Any information would be appreciated.
Oh yeah...I did check with both companies, but neither have responded to my question yet.
