as a new dm , i got to do my first official class for pay this weekend, and was given my first expirience at a panicked diver, new diver on last cert dive lost his reg and as i was bolting to assist he recoverd but didnt clear , got a breath of water spit out reg and began to flale, i was able to grab his hand restore his reg and while holding this diver calm him enough to get him to sit and breath a moment, and then talking (signals of course) get him to relax, still seeing panick in his eyes and face, and the death grip he had on my hand, i continued to stay with him and he then asked me to take him to the surface, on the surface he calmed down thanked me for the help and comfort of knowing i was there imidietly to help, minutes latter had me take him back down and he finished his cert dive and then i took the group on a pleaser dive, he did well and i got a real new expirience, thought id share this with all to comment on.
