i think you missed reading post#12 above.half the stuff they are advertising sounds like a Discovery dive. This is also called a resort course. They give you the bare minimum of training (usually not enough if anything goes wrong but enough if everything goes as planned). They do some pool exercises then they take you out for an open water dive. After that you are certified to go for open water dives with a dive instructor present. This is not real certification. If you go to a new resort, I believe, you have to take the training over again.
anyway, not trying to promote one thing over the other, i'm quite sure whichever way he goes, it will be added advantage; besides, nobody can assume that resort certified divers "die" any time once they're away from their instructors! for the rental gear there, i can assure you, even with the modest dive operators, it is in a well-maintained condition, even regularly inspected by authorities, which is expected as everywhere when you have people are making their living from that; not sure though about less frequent diving places.
Oh, BTW, OH surgery is way more advanced in Egypt than you think it is, in fact, the leading UK heart surgeon is Egyptian.
