I just got back from diving in the Gulf Of Thailand off the Island of Koh Tao. They used metric on weights and BAR instead of PSI so I brought my own 1rst and 2cnd stage and my dive computer. Everything else was the same. S,M,L,XL BCDs and they had nice equipment otherwise. Any other questions feel free to email me I also have a bunch of pics with my SCUBA camera I can share.
