Personal transponder advice
 

Just thinking about getting a pt I race in the uk and now and again the usa which pt will give me the best coverage in both countries Thanks in advance

mylaps harry or MRT's new one I recommend MRT over mylaps

Either the Harry or the new MRT - both will work fine. I prefer the MRT as its both smaller and cheaper, but I guess the Harry is the safer option.
The Mylaps/AMB system is used all around the world so as long as its compatible with RC3 and RC4 you can use it pretty much everywhere. The only exceptions are clubs that use IR systems or older AMB's and you'd need something different for those anyway.

Thanks lads mrt sounds good if smaller and cheaper who stocks them in the uk or are they a direct from manufacturer

I saw some MRT's on eBay but no confirmation they were the new ones so order direct from MRT. The ordering 'system' is a little slow, you need to email them and they'll send you a link to pay but stick with it.

Thanks for all your helpfull advice lads good stuff
