I have been becoming more proficient at diving as I was just certified with Amigos Del Mar in February. I have since returned to San Pedro six times and ALWAYS dive with Amigos del Mar. They are the most knowledgeable, professional, and just greatest people to dive with...there is a reason that other shops refer divers to ADM for longer trips, and even for smaller ones. If you need more information, and recommendations, just do a search for ADM on this board. Good luck and have fun!!!
