Hi Kenny. Sorry for the delayed reply, I haven't been on here for a while. I've been running a divemaster course with 15 students and 2 other instructors for the past 2 weeks. Anyway, shame my previous message got lost in the hack. I hate the fact that you can't reply directly to comments or see what you've sent. I think you asked about cave diving and work possiblities?
We don't offer cave diving speciality as a standard course here, primarily because there aren't any caves However, there are some freshwater ones north of Bangkok so it can be arranged. If you are interested or want more information you can contact the dive centre by email.
With regards to work, it can be difficult because you need a work permit to work legally and they are not easy to get, but you should be able to find freelance stuff once the high season starts around October, although not with Mermaids. I'll have to check your message again to see if there's anything I haven't covered. S'later
