Since you're asking... you should probably find out what type of timing system your track has... there are a handful of systems out now... and none are compatible.

Out of the AMB's... if the track has
AMB20 or older - will NOT accept personals
AMBrc - will accept personals
AMBrc3 - will accept personals
MyLaps rc3 - will accept personals

Personals that will work with the above systems
AMB DP (Direct Power)
MyLaps rc2
MyLaps rc4
