I was on the Aggressor II for the trip 11-18 Feb 10 and would like to add some additional information that may fill in some gaps regarding the initial report and the replies and questions. My understanding was that Eloise was a qualified Master SCUBA Diver with 50+ dives experience and not a Dive Master. Her last dive, according to her declaration, was during April 2009.
Before the second dive of the trip I was interacting with Eloise regarding measuring her nitrox mix and setting her computer to reflect the reading. The mix was 32% nitrox. She was not familiar with how to use the sensor so I showed her and advised her that her computer needed setting to this reading. She had a 'Gecko' dive computer so, using her abbreviated instruction card, we set it and checked her PPO2 setting. It appeared to me that she was not very practised in using nitrox.
During the initial phase of the dive I did notice her descent from the 'panga'. I noticed she was descending and was holding her demand valve in her mouth with her hand. Although I was concerned by her relative inexperience and the fact she had not dived for a year, I was reassured by the fact that her buddy was a Dive Instructor.
Thank you, Keith, for your post.
Do you know how the two divers became separated?
Was the victim undergoing some kind of instruction?
