Gday mate, yeah its a Tech 2 scantool. Just a cheap chinese clone one, but it works excellent. It works on all aussie holden cars up to 2011. Ive used it a fair few times now with no problems at all. Its got way more stuff to muck about with than the tech 1 had, takes a bit of getting your head aound some of the stuff on it, The aussie software card is the thing thats hard to get hold of , and expensive too , it costs nearly as much as the machine. The software cards I can get are genuine bosch cards though, not counterfeit chinese ones. The seller I bought the machine from in china was supposed to supply me with the aussie sioftware card, but when I recieved it, it was just the holden export software card, it only has chevy luminas etc listed on it, V6 and V8, no other holden cars are on it. I think it still works on our commys though,Ive been told it will,but I havnt tried it out yet.Cheers mate.
