My 14 year old son is a certified diver, but he has not had a chance to dive for a few years. I want to find a refresher course for him as well as a dive master we can trust to be his "buddy" throughout his dives. I have a quote from Banana Beach and I know they are excellent. I want to get a few other ideas and quotes, as well. Of course, we need a really reputable company that comes highly recommended. We will be in San Pedro on Nov. 23.
