Any track I have dealt with where you have to buy a transponder, the transponder is yours. It is up to you to make sure it is in working order, just like a raceceiver would be. They did say they will have a few to rent for each night. Even if you do rent one, if you damage it or lose it, you are still responsible to replace it.

The part I do not understand, they say to mount it on the right rear axle tube. Might be OK on a late model, not so much on a sprint, lol.
