I see from today's Yorkshire Evening Post that Bradford are trialling a GPS system in the game next Sunday.

There are many obvious jokes here, some of which I am sure you would love to shjare. But what is this all about? Apparently it will help us close the gap on the Australians

bet they'll be just as applicable when you consider leeds have been using the same system for training purposes for a few years.

Not quite the same system - the one the Bulls are using is a little more sophisticated than the ones that we've been using but fundamentally the same and nothing new.

So the rumours are true that Australians can’t really play rugby league and get satellite navigation to help them?

Should be banned IMO because its cheating.

Maybe they should fit one to Ryan Bailey – help him find his way to the line?

yes but what does it do and how does it help rugby

Saints should put one on Leon Pryce to find out where he goes once the team bus arrives at Old Trafford

I reckon there's a greater chance of them losing their sat nav than there is of them finding Pryce.

Its' used to track player movement during training/games and calculate the distances covered, AFAIK

it can also monitor, fatigue, heart rate, pulse etc so could be used to time when a substitute is needed

Is it monitored live or is it simply recorded to look at after the game?

Its a live system, and can be used to know when to sub certain players. England used it in the 4Nations FWIR

Was it the Sat nav that told the coaching staff that McGuire and Smith couldn't handle Inglis or did the coaches look up from the screen at the pitch?
