Transponders

[whites75]

Sorry the class clown here again (ahem)....until a few days ago I wondered how the hell do you tell the finishing order in races, then, if I am thinking right I find that cars have a transponder in them to relay the lap count and timings tp the computer controller/

Does everyone generally buy their own, does one transponder work on all tracks or do you need a few different types to work on various tracks?

What sort of price are they please

Generally one transponder will work at pretty much every single track.

There are two brands to choose from, either 'amb/my laps' or the 'mrt'

For ease of mind personally I'd buy a amb/mylaps transponder. You have a few different models but buying a 'Harry' model will work everywhere.

Buying new is £80+ buying second hand is £45+

You can buy the 2 wire Amb on eBay for £65 plus post from the US here:

This is the hybrid or "Harry" that should work in almost all tracks
