So long as your track is using a current or older AMB system any of those transponders should work fine. The nice thing about the MRTs is they are less expensive and you can get them all cloned to the same number so you only have to remember one. I bought a used AMB to get my current MRTs cloned...I just haven't had a chance to send them in yet.
Our track has already made the conversion to the new decoder software on the offroad side, onroad side is coming soon.
The AMBrc DP, MyLaps RC4 Hybrid, and MyLaps PureRC will all work with version 4 of the AMB decoders.
If your track is running older AMB decoders, the PureRC will not work, but the MRT WILL work.
To be on the safe side, and get one that will work in any case - get the AMBrc DP or MyLaps RC4 Hybrid.
