The 300 bar tanks we use are mainly AGA/Interspiro steel tanks, Swedish manufacture. They used to come in double 7's, but nowadays they only have double six and double four litre tanks. Then there is the Poseidon, also a Swedish manufacturer. They have 6, 10, and new 8-litre tanks in 300 bar range, all of them steel. They can be rigged up in any configuration. They presented a set of double 8's, which is very interesting for wreck divers like me, but probably too big for Your use (I don't know too much about cave diving). In addition, we can get German Heiser 300 bar tanks (6 litres). In general, the Navies of Finland and Sweden use AGA/Interspiro gear, as well as Firefighters and rescue people. Therefore we have always had lots of that stuff around. I've gotten the impression, that 300 bar gear is much more common in nordic countries than the rest of the world !? I know that it's getting more familiar within tech-diving community across the water. There was a Tech-diving seminar at the Polytech in Stockholm, Sweden this November. There Imre Botos from Interspiro introduced their new composite tanks (cross-woven carbofibre), which were REALLY light - You could lift up double fours with a straight arm! And what's best, the tanks are for water diving, not only smoke diving! And the idea I got from Imre's presentation was that there really is no pressure limit. Only problem is probably the price, which I didn't even ask for... For prices and such information, I think You'd do best to contact dealers for Poseidon and Aga/Interspiro in Switzerland. If You need addresses in nordic countries, I'll try to supply them, just let me know. Don't get lost in them caves, I hear some of those You got are kind of big. Nice dives, Juha
