Went diving with a few friends at well known "easy" shore dive. A group of about 10 divers from one of the LDS was there for an organized dive (they all signed waivers etc..at the dive site so that's how I know that this was an "organized" outing). Their DM, after collecting their waivers, decided to give the pre-dive brief...while smoking a couple of cigarettes (nice example to give). The group consisted of mostly OW divers with VERY little experience (I overheard half of them say that that they got certified a few years ago and hadn't gon diving). Only a couple within the group had dive this wreck...granted, conditions were pretty nice, vis 30 feet, water temp 75, depth 40 feet. We decide to hurry in before this group ruined the vis. After about a 40 minutes dive, we started to see some of the group following the guideline to the wreck and starting their dive (it took them a crap load of time before getting into the water). Luckily, we were finishing our dive cause this group was all over the bottom! :upset: After ascending, we noticed that the DM hadn't gone in the water. He was just lounging on the shore having another cigarette; I don't even think that he had gear with him. I approached the DM and told him that I was a bit worried about the group that was down there. His response: "They all have there c-card and they all signed the waiver"! My buddies and I decided to hang around on shore until the group was out...just to make sure everything was OK. Everything ended up being OK but two of the ladies ended up coming out of the water with their tanks hanging by the hoses (and not the tank band!) What a mess!!!
