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. 

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!!!

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!!!

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 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.

Tech Diving Thailand is a great place to learn Technical Diving. I went from Tec 40 to Tech Instructor.. They offer many other courses like cave diving, equipment repair, gas blending, sidemount, rebreather and many more. Instructor trainer David Polley is very experienced and has a lot of diving knowledge that he happily shares. If your on Koh Tao don't bother Tech diving anywhere else, do it all at Tech Diving Thailand.

Getting into Cave Diving

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

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!
