Bryan, right now I am taking my SDI AOW course (deep, night/limited vis., navigation, basic nitrox) and also Dry suit with PADI. It's a good question, to where to head from there? I was considering SDI solo diver - partially for the reasons I mentioned above and partially because it looks a serious course where one can learn a lot. I also made thoughts about a GUE Fundamentals. The more I read the AOW speciality manuals, the more I realize that there is nothing new in them. It is all about the same OW skills, esp dive planning and buoyancy control, only in somewhat different conditions. GUE F seems to be a serious re-visiting of these basic skills. (I use BP&W anyway). If you say so, may be I should have a closer look at the Divemaster course.
Saxatilis, good for you. I really hope to find good instructors, too. Did you encounter situations, when your solo cert was not honored by the dive centers?
Jim, what do you think - GUE F or SDI Solo?
Thanks!
J.
