is that all the scuba operators in Hawaii operate as a big cartel, fixing prices across the board so they make huge margins off unsuspecting tourists. Most scuba schools take 3 to 4 days to get you certified - you need to plough through a 250 page PADI textbook and do a bunch of drills in the swimming pool. This is all a waste of time because a) most of the stuff in the textbook is fluff and b) swimming pool conditions are hardly an accurate simulation for open water conditions. Ken (from Rainbow Scuba) doesn't waste your time. My first day of class he puts me in a wetsuit with all the gear and throws me into the sea. At first I think I am going to drown, but quickly realise that this is the best way to learn. He was patient, extremely knowledgeable (as can be seen from other reviews) and entertaining with his French jokes. We learnt the basics very quickly as scuba is the sort of thing you need to do practically as opposed to read about theoretically.
The other thing you need to consider is price. Most places will list their prices for the PADI open diver course as $350 to $450, and this may or may not include the price for books, equipment rental, "admin fees" or whatever other charges they can slap on you. Ken's prices are way below that and the number he quotes you includes everything, No hidden charges.
Basically, if you want to do business with a honest guy and get PADI certified in one and a half days (which is all you need, really), then Ken is your man. Knowledgeable, weird sense of humour and no [--]
