The Hybrid transponder is the one to purchase as it will work with both RC3 and RC4 Decoders. The RC4 only will not work at all with earlier RC3 systems and many clubs still use RC3

There's also the MRT PTX, works with all systems.

These seem crazily expensive for such a small piece of kit surely there isn't much to them

This is the way to go
