For curious minds:
On the subject of the computer, the DM or more accurately DM/Captain was attempting to hook up the computer to the SPG hose. I do not know why the regulator suddenly started to free flow. The equipment was mine, not the dive shops. This never happened before and has never happened since with this equipment.
I dive very conservatively within the tables, always make a longer than necessary safety stop, and follow the divemaster's plan with respect to bottom time and depth. I also generally prefer not to go below 80 feet and I always ascend with a dive buddy. I consider a computer more of a safety check device than an infailable(sp?) instrument that tells me the limits what I can do. Up until my Hawaiian dives, this has not been an issue. If I was diving individually, which I don't, I might consider a computer more of an essential piece of dive equipment. Individual ascents/dives seem to be more accepted in Hawaii than other places that I have dove. Sorry if I seem old fashioned to anyone.
The incident with the DM/DI had to do with equipment, safety stops, uncontrolled ascents, embolism, diving history, diving skills, diving knowledge, DM/DI responsibilities and attitudes. I refused to dive under those conditions with that DM/DI and would do so again. Apparently, the DM/DI had a history of conducting themself in this manner whenever anyone questioned their decisions. It was not just this incident, but also the history that I believe led the manager and owners to indefinitely suspend the DM/DI for their professional conduct.
I hope that answers everyone's questions.
