My reading of this is that hand-outs won't work either. Really can't see how MRT's won't but they will. Add to that the fact some clubs actually use MRT's as handouts and there is a clear problem.

Mylaps don't actually like handouts (they stopped making them a long time back and don't support them) but any club that has them will tell you how useful they are, especially for new members.

That means I can't see many clubs clamoring for RC4's right now - unless this new Percy PT is really cheap and can be bought in bulk it is not in their interests. Mylaps are sort of admitting this themselves between the lines with the whole 'free upgrade' bit - you never offer that sort of thing unless you need to coax people into changing.

For nationals I can see the advantage, so them going RC4 does make sense. If you are paying for nats anyway the cost of a new transponder is a drop in the ocean. But then your shiny new PT won't work at a club meet because they haven't upgraded......
