Glad to see you had a lot of fun and no problem with the French system :cool2:
We just came back from french polynesia and one of my friends, a PADI Dive master + Advanced Nitrox IANTD was refused access to diving because he had a pacemaker. He had a letter from his cardiologist, saying he was able and from a pneumologist, saying he was able but not one from a "Sport doctor", which is the french "rule"..
Luckily enoug he ended up diving because one of the dive professionals, that personally knew the guy that granted him is IANTD, accepted to "break the rules" for him.
If he would not have been there and flexible, I am not sure that my friend could have dived.
FYI, my wife and I, we have the same credentials and we were not offered to dive independantly. We had to dive with a french dive leader. That's OK with us, we prefer to dive with a local DM, we enjoy our dives much more.
Everything went finally fine, but one has to know that some people can stick to the letter of the rules and be pretty stuborn
. So a good piece of advice is to take contact with the dive operator before hand.
