I don't know who the owners of the shop are, but Jeanetta Southard is the supervisor and was very helpful via email when I was planning my trip from Japan. On Saturday I dived with Cathy to The Crevice and Finger Reef. On Sunday morning I dived with Tommy to the Blue Hole and Seabee Junkyard. We took our requisite photo at the Blue Hole, then Tommy guided me to a reef nearby which was really nice and relaxing with lots of fun stuff to see. The Junkyard was indeed a junkyard and quite murky (well, at least compared to the 100ft+ viz on the previous dive), but I still enjoyed it.
