I learned more getting my Rescue than any other certification short of a professional designation (Divemaster and Instructor were even more enlightening).
The most important thing about getting an advanced certification like this is not just that you can be a better buddy and dive party participant, but you learn to be a better diver, and are better able to respond to situations you, yourself, may face! If there was one thing that I took away from my Rescue course it was
STOP! Think. Act.
Do it. Tough training, but well worth it.
