Many thanks for all your reply.
In fact, my original intention is just to improve my diving techniques. I can be comfortable underwater. But still, there're times that I think I should be able to do this better. That's why I'm looking for some further education in diving. And my friend has told me about BSAC. It sounds that BSAC is a good institute. That's why I'm thinking of taking the course.
If you have any suggestions, I'm very happy to hear
As someone from inside BSAC. The training provided by
BSAC Thailand is conducted on a commercial bases, not club based. However, the certifications awarded are the same as those gained in the UK (commercial BSAC Centre or BSAC Branch).
Your current certification level, see
here, will dictate which level you may start your BSAC training. However, there is nothing preventing you from starting at the beginning, if you so desire.
In addition to being able to dive to 35m (following qualifying dives), a
BSAC Sports Diver will be trained to use Compass, Surface Marker Buoy, Delayed Surface Marker Buoy, Nitrox (up to 36%) and be certified to undertake dives requiring Deco stops, plus a BSAC Sports Diver has been trained to rescue there buddy and assist in dive site management.
As a BSAC member there are a range of
Skill Development Courses you can take.
You don’t have a location in your profile, maybe another BSAC franchise location would suit you better.
And as for having to learn in the UK, that's rubbish. I trained in 1979, in the Caribbean as a BSAC 3rd Class Diver (as it was then called).
