Thank you all for the info. Sorry for splitting threads, but I was not getting any info by posting to a thread fromm 2007. I'm new to scuba board and aplogize for the mistake. Won't happen again. I have spoken to our dive shop here and they were not super helpful with information, but suggested that we just look for a 5 star padi IDC, what is the difference between 5 star and just a PADI dive center?? Obviously they have to meet certian criteria, just wondering what the 5 stars actually mean?
