To: techdiver@aquanaut.com Dear Peter, I am well aware of what you are calling a rebreather accident. But if the only rebreather accidents that are counted are those where the rebreather has to break before it become a rebreather accident then there are almost no rebreather accidents, which we both know to be BS. As George has repeatedly said, a rebreather is a tool to use when the mission objectives cannot be attained with any other means. All rebreathers are deadly, all rebreathers are dangerous to greater or lesser degrees, some are better than others, but they are all more dangerous than standard Open Circuit equipment. As far as the number of accidents per rebreather sold goes, I doubt that Halcyon has sold 20 RB80s, that's a 10% accident rate A far as the Halycon PVR-BASC (refridgerator) goes, I also doubt that more than 20 were sold, that's a 5% accident rate. Then comes the CisLunar Mk 5, 3 deaths total. Next is the CisLunar Mk3, 1 death. Buddy Inspirations have been hanging in there for years with accident rates around or less than 1% for years And yes there are rebreathers with a lot less than 1% accident rates per unit sold.

When discussing rebreather accidents, one must distinguish between two types: - The accident occurs as a direct/indirect consequence of the rebreather in question - The accident _might_ just as well have been on OC. From what I gather from the RB80 accident (and Michael, neither you nor me know about how many _accidents_ there have been on the Inspiration, so your claim of Halcyon having the largest number of accidents is just plain ludicrous) it could just as well occurred on OC (the broken neck seal). Furthermore it was an _accident_ as opposed to the numerous Inspiration _deaths_. The same of the Dennis Harding PVR-BASC death. That had nothing to do with the rebreather itself. Of course, we don't _know_ whether a lot of the Inspiration deaths were due to the machine or not (directly/indirectly) - as most of the dead divers were diving - solo, the mother of all fuck-ups. -- <greeting> Best regards </greeting> <author> Peter Fjelsten </author> <location> �rhus C, Denmark </location> -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
