Took the July 2007 San Carlos trip with Oasis, for my open water checkout dives. Completed my dives. Shore Dives off the Hotel and Boat dives at Martini Cove. Still had time for 2 (Boat) sport dives off Little Waterfall and 1 (Boat) night dive off Deer Island. I can confirm the disposable Fuji water cameras (rated for 35 feet) are good down to 50 feet. Another guy on the trip can confirm... They do not howeverwork to 100 feet. There are a number of other sites and attractions around the little area there too. Though they don`t appear to be developed or marketed very much. From the hiking trail to the top of one of the mountains. To the ruin and airfeild from the set of a movie named "Catch 22". There appears to be pleanty of reasons to make return trips here.
