Great tec course with great instructors Dave and Tom. I also did the course with a friend I've been diving with for a few years and so felt very comfortable getting used to all the new skills and techniques with a very fun and motivated group! i eventually planned and completed my own dive, dived a brand new wreck and even got to spend a decompression stop with a Whale Shark! cannot wait to go onto my Tec 45!!!

Cave Diving with Tech Diving Thailand was awesome! I took the TDI Cavern and Intro to Cave courses in Khao Sok National Park. The food was great - a variety of Thai cuisine - the accommodation was simple and beautiful - floating bungalows - and the people were professional, safety oriented, standard conforming and super fun. Highly recommended!

I did Tech 40, 45, 50 cavern and intro cave with Dave Polley last year. Dave is a fantastic teacher, very professional and knowledgeable and trains with a relaxed and enthusiastic approach. It was a great experience pushing my diving into new areas, tech training also improved my recreational diving (trim, air consumption and planning) The cave and cavern trip too Khal Sok and Song Hong lakes was a definite highlight of my time in Thailand. Will be returning tooTech Diving Thailand and Dave for Sidemount in the near future.

I did my TDI Trimix course with David Polley on Koh Tao in 2012. Being a PADI instructor and a TDI Full Cave Diver before, I can really say that this course put me and my diving skills on a new level. Not only the knowledge about and usage of different breathing gases, but also all the other technical diving techniques that are part of this course. Since we went on a wreck diving expedition after the course, Dave conducted the course very thoughtfully, providing lots of tipps and tricks based on his year long experience and made sure that me and my equipment would be perfectly prepared for the expedition. Great job, Dave, thanks a lot!

So I recently did my PADI Tec 40 & Tec 45 with Dave from Tech Diving Thailand, I have to be honest I was a little apprehensive going simply because I really didn't know what to expect. However, when I met Dave for the first I realised that it was going to be a good course. Daves knowledge is extensive but what struck me most was his passion & enthusiasm for this particular area of diving, throughout the theory sessions we would often digress into the background behind the theory and to watching videos of his many exploits diving on historical wrecks. The practical part of the course was not easy but this was a plus point, there was no coasting along through the skills, Dave made the emergency drills as realistic as possible but also ensured that my understanding of the skills was up to scratch. There was no real section of the course that I preferred as I found it all challenging and therefore enjoyable.

Great tec course with great instructors Dave and Tom.

I did my Tec deep Instructor course, intro to cave and dive shop operation course with Dave at Tech Diving Thailand. Had an awesome time, very professional outfit and knowledgeable instructors who could answer my questions in detail and made everything easy to understand!! Would highly recommend!!!

I have done several technical diving courses with Tech Diving Thailand and I have to say the level of expertise of their instructors is unmatched in any other Tech School I have been with. I completed PADI RecTech to Tech 50 and TDI extended range, cavern, intro and full cave diver. I particularly enjoyed the cave courses, conducted at Khao Sok national park and Song Hong, a crystal clear sinkhole, with near limitless depth potential! If you are learning to tech dive do not trust your life to any other school Tech Diving Thailand are the best.

I did my TDI Sidemount, PADI tec40, TDI Advanced Trimix to Full cave diver with Dave. they were great fun. We went on a great cave trip up to Khao sok national park - which was beautiful we stayed on floating huts and had interesting food most nights. We also went to Song Hong sink hole which was incredible. The cave was huge and dark it was like diving through space. Learning technical diving is very demanding, but hugely rewarding experience

I did my Open Water with Dave when I was 54. I’m not a brilliant swimmer and I didn’t like having my face in the water let alone underwater so it was very challenging for me. However, Dave proved to be a brilliant teacher and taught me the skills I needed. I’m his Mum so of course, you’d expect me to be biased but actually I had no idea of his teaching ability. I also thought he might be a bit impatient with me but not at all. He was so professional. Being underwater was a fabulous experience.
