I have my Nitrox already and I am glad I took that when i did, it exposed me to another agency. TDI which i believe will be my agency of choice for my future classes i would have liked to take GUE fundamentals class but since i don't use a BP\W i was told i cant take it. I willdo some diving then start more classes begining of next year.
I'm not sure if it took hold but last year GUE announced DIR Essentials. This was a GUE course that is tolerant of mainstream gear.
