OK, I searched & didn't see anything that really fit this mold. I was hoping to start taking this course back in Jan. or Feb., but my instructor had lots of trouble getting those interested in the course to come to an organizational meeting. Of those that eventually did show, a couple are high school seniors & asked that the course be postponed until they get out of school (May). Now it looks like it may be postponed again because they don't turn 18 until late summer or early fall. There is another diving instructor nearby that is SSI & IANTD. I want to continue my diving education, but find myself torn between my ambitions & my loyalty to my instructor. I like her style of teaching & have had her for most of my courses. The other instructor is also good, as I've had him for a couple of courses. I'm not quite as familiar with him as I am with my first instructor, but do plan on going with him for technical as I also have an interest in technical diving. I'm not looking to get flamed, but would just like to know what some of you might do in this situation. Should I just wait it out & continue to gain more experience? Or try to go with the other instructor? What are the major differences between PADI, SSI & IANTD for Dive Master/ Dive Con? I am also not looking for a war of the agencies, just trying to get an idea of what the differences are. Just looking for some different insights, to decide on a path. Thanks.
