Nearly, but not quite right Emma. Players can sometimes take their own markers along to DF sites (usually tippmans/mechanical spiders/inferno t3's which don't give them the advantage of say an Angel) but they MUST use a DF site bottle (co2) They can't bring their own co2 OR air bottle onsite.
This came about partly due to events in the US earlier this year where a player was taking down his marker at the end of the day and unscrewed the valve from the co2 cylinder, killing a woman standing nearby. Also due to a player turning up at one of our centres this year with his own marker, co2 bottle and valve 'straight out of the box' and not having a clue how it works, he screwed the co2 valve onto the bottle by hand expecting to be able to use it! The marshals informed him that he must get the valve fitted by a trained person and the correct threadlock/torque must be used and he used a site bottle for the day. Scary **** really that wholesales actually sell co2 bottles and valves to the general public, though most have stopped this practice now thankfully. E-Bay however is a different story...
