miketsp:As you say it's not the subject of the thread and trust me dives have been well discussed elsewhere. However just for the record, I would have had no qualms about doing the dive on my own with my wife if we were the only pair on the boat, without the guide. My navigation and night diving skills are good.
However, I believe the issue here is a basic safety one that there was a plan and the group was diving as a group and the splitting up of the group would have caused additional unnecessary complications under the circumstances.
Remember that it was also necessary to resurface with lights out at the end of the dive.
Sorry if you took it personal. It wasnt meant that way, and if I offended you, then I apologize. I wasnt questioning your dive skills, I was questioning the dive plan.
I wasnt going to reply as I dont want to turn this into a discussion about group diving being nothing more then diving in the same ocean at the same time. But....This whole dive plan sounds convoluted, as it makes you way too dependent on the guide. I can think of a number of reasons why a diver, or buddy team, would need to surface, or does surface, before or without the others. What happens then?
If someone has a problem, does the whole group goes to the surface together? And how is it conveyed to the whole group (that may be spread out) that there is a problem? Does the guide surface with the diver(s) with the problem and leaves the group below? And what happens if they cant get the guides attention in time. Or do the divers with the problem surface alone. What if a diver does surface with out the group as planned? What then?
