There is a woman called Maggie who does courses - has been in Jeddah for years. I do not have her contact details but if you call Bob Wilson (the sports officer at the Al Bilad Hotel) I am sure he will have her contact details. My wife, my son and I did courses with her during our first stay in Jeddah. Or e-mail Andreas Wolf at
jeddahdiving@hotmail.com - he used to courses in Jeddah but has moved to Riyadh - however, he says he has contact details of reputable dive trainers in Jeddah. His mobile number is 050 955 10 59.
