Just because one doesn't take the Rescue course, doesn't mean you will never run into a situation where you'll need the skills. I had just signed up for the course, viewed the video, and left for a week to dive in Bonaire. While there, a diver ran into a panic situation (low on air) and bolted to the surface. She passed out on the surface and I had to tow her in to shore, remove her gear in the water, and another buddy helped me get her to the truck to transport her to the hospital. You can bet that as soon as I got home I contacted my instructor and said I was ready to take the class!
