I did the Rescue class a few weeks ago and it was interesting for several reasons. I took it through a shop I had never dealt with before since my usual charity was done doing them for the year. As with most of my hobbies I do a fair amount of research when I am heavily involved. As a result I had read the material thoroughly and found that some of the information presented in the class to be incorrect. I understand, it happens to the best of teachers.
While doing the dives I found that the instructor and especially the divemaster were less than appreciative of my gear selection. I wear a bp/wing, use a long primary hose, etc. It was felt that it just be a matter of time before I became a statistic,and not a good one. I kept quiet and went through the class. On a side note, I had dived before with one of the guys in the class and he normally wears a bp. For the first day he copped out and wore a back inflate BC. On the second day he wore his plate so we could do the equipment removals in what we normally wear. So, instead of one future statistic the instructor now had to deal with two.
It was a good class but I could have wished for an instructor and divemaster who were a bit more up to date on "emerging" trends. I truly believe that this was the first time they had seen a bp/harness setup.
On another side note, two weeks later a friend who had not been diving since January and had only dived in Cozumel called me up to go diving here. I picked what I felt would be an easy lake to dive in since conditions here are a bit different. My pick was bad. The water temp was getting into the lower 60s at this point and the viz was down to about 5'. He wanted to go ahead anyway. As we started to descend he ran into problems. It was rental gear, he was not used to a thick suit or hood, as well as some other issues. I was at about 3' and notice him head back up. I came up to a very large set of eyes, the mask is off and the arms are starting to work. We spent about 10 minutes while he calmed down and rearranged gear so that he would be more comfortable. The dive proceeded after that. It is amazing how quickly someone can get worked up. Even on the surface floating nicely it took a bit for him to calm down. The rescue class was worth it due to this event alone.
