Some Great advice here thanks!!!
Regs will probably be XTX50's.......... I'll get the cyinder O2 cleaned as I don't think I'll be that long before I do my Nitrox course........
I think I'll end up going for a shoulder dump and have a play in a puddle to get the settings right ..........
Thanks again and watch out for a post asking for volunteers to help me get the shoulder dump set up
