Ben Reymenants is one of the most experienced technical dive instructors in SE Asia. I did my CCR Trimix and CCR Advanced Trimix courses with him recently. I chose to do the courses in the caves of Song Hong and Sra Keow, as this provided an assurance that the courses were going ahead regardless of the weather. The ambience of caves was an added bonus. The alternative of basing the course in Phuket and going out to sea in day boats was offered.
Ben's approach was incremental, ensuring that skills were learned properly, before moving on to the next stage of training. My comfort level was challenged at times, as it should be by a course at this level, but I always felt safe. As a trained dive medic, and an experienced hyperbaric chamber operator, Ben has a deeper appreciation of diving physiology and decompression theory than most instructors.
Transport, food and accomodation while away at the caves was included in the price of the course, though food and accomodation while in Phuket was not. The local Thai food at the resort near Song Hong was excellent. The rooms were clean, tidy, and well kept, but don't expect 5 star accomodation; this is a rural district in a third world country. The logistics of tanks, gases, and other supplies required for the course were well organised.
I really enjoyed doing these courses, and I am a better diver for having done them.
