People go into the Rescue course thnking it’s a "diving" course. It’s not. You already know how to dive when you take that course. It’s a course designed to make you a better buddy to anyone you are diving with and how to help you deal with emergencies without becoming one yourself. When any of my folks go into the Rescue class, that’s the first thing I tell them. You learn a lot in the class if you know you aren’t there to learn to dive.
