They're using Hawkeye though. I reckon that's dodgier than snicko.
how so?
I'd say it is way dodgier and I'm surprised they'd use it ahead of Snicko.
One records audible sounds which are fairly conclusive in determining whether there was contact with the ball and when and what kind of contact it was (sharper for bat, duller for pad, etc). Hawkeye uses technology to estimate the trajectory of a ball that's course has stopped. I'm not so sure it can really be done with 100 percent certainty, while the other can. There are a lot of variables to take into account (bounce of the pitch, for example) that could alter the trajectory. On a few occasions the trajectory projected by Hawkeye have looked a bit off to me.
