Did my tech 40 & tech 45 with Tech Diving Thailand Tech and I was very happy with the experience. Doing tech is an interesting experience. Even though I'm an open water scuba instructor, everything is so totally different with tech that I felt like I was doing my open water course again. Schmike (Mike W.) was fantastic as an instructor. He was super knowledgeable and made me feel comfortable all the way.

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!!!

Getting into Cave Diving

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.

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 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.

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 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

Thank you Dave for completing my Sports Diver training qualification in record time! I had barely finished my Ocean diver course when Dave suggested that I pursue diving to the next level. In less than 2 months, we covered the entire diving theoretical content in 6 lectures, went for shore dives, sea dives, etc... And finally, passed the exam with no trouble at all!
Many thanks again!
