I just signed up for classes for ANDI certification and have researched their offerings on the internet. What I found on their site isn't exactly compelling, it seems to only answer instructors questions, nothing for the end user.

I have wanted to dive for quite some time but want to be sure that my certification will allow me to dive 'anywhere' I travel. I'm going to Hawaii in a couple of months, but want to be able to rent gear and dive 'round the world.
