scubadee . I had sort of a similar experience at Blue Heron Bridge on a sponsored night dive. I have no idea what experience level the group was. The dive / dive master leading was awesome, but the group instantly went into a " Let me see frenzy". Not paying attention where the other divers were located, divers running into each other, silting up the bottom and such. After about 20 minutes of this I decided to hoover above the frenzy a few feet. Turned out with a light mounted on my OTS FFM as a secondary, while using a primary light, I was seeing things that the mass was missing. A lot of things. After about 40 minutes, I watched a diver shoot to the surface about the same time I got my first experience with fishing line. I untangle myself and noticed the DM leader had surfaced due to the dive flag being entangled . No one else surfaced, they all stayed fixated on the "Let me see" . I surfaced, asked the diver that shot to the top if he was OK . He ran out of air, asked if he can inflate his BCD orally , he had already. Check that the DM was OK, and escorted the OOA dive back to shore. Personally I don’t think a cert has anything to do with how people act, if they are an elitist/entitled/me me me attitude above water, really don’t think that is going to change underwater. I’ve had my AOW since 87, but just have got back into it ( basically starting over) with 15 dives since Jan 2015 ( Springs, Quarries, Ocean), so what do I know. Enjoy ..
