Robert, the right had 2000, but that was in the sun. It fell back to 1900 or so when cooled. It problably only had 2400 or so to start with. The other had 3300 when we checked it, but could have freeflowed in transport. Maybe the guage was wrong and it really only had 1100. Either way, it was not empty as was originally claimed. The reg was working, you and I tested it at 260 when we went over our checkout when we found the body on the bottom. This is the same reg I use in my rebreather for an oc switchover on the mouthpiece assembly - I know that reg ( you do , too). The girl was a triathelete, and had a very low breathing rate, according to her boyfriend. You and I both know from our extensive rebreather work that CO2 will build in dead space immediately, cause the mind to falter, and precipitate a blackout. However, it makes no difference: there were reports of many problems ( possible head injury prior to the dive, bc and buoyancy problems, problem with getting gas from reg which had a com link on it, all noted by the "instructor" and others in the dive. What happened next is the issue: instructor failed to stay on her, and failed to rescue her when she blacked out, and then failed to go after her and get her, which , as I proved Sunday with my two dives, would have been no problem from a gas management point of view, from a decompresion point of view, from a time point of view, or from any point of view. I will also point out that I am 47 yeras old, and if I can do it without injury, a young "instructor", who is supposed to be an expert, should be able to do the same. He should also know enough about decompression to realize that getting her and bringing her to the surface for the boat and then going back to deco, which is what I did on my second dive Sunday, is sop in an emergency like this. Everyone wants to make excuses - there are none. You go in with buddy or student, you come out with buddy or student, and you do whatever it takes to save a life, and worry abvout the consequences later. You provide safety crews on the boat you teach from, and you provide addequate coverage and rescue for your students. Period. This is an open and shut case. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'. Send subscribe/unsubscribe requests to `techdiver-request@aquanaut.com'.
