Planet Tech is a technical scuba diving school based on Koh Lanta, Thailand.

You have the opportunity to do technical scuba diving with some of Thailands most spectacular marine life - mantas and whale sharks. We dont believe that technical scuba diving should always be done on the sand! On a technical scuba diving course with Planet Tech we guarantee technical scuba diving at some of Thailands best diving spots - Hin Muang / Hin Daeng and Koh Haa, for no additional cost. you could also become certified at Thailands top diving destination - the Similan Islands. As well as reasonably priced DSAT and TDI technical scuba diving courses at Planet Tech you can take advantage of Thailands cheap food and accomodation on one of Thailands most beautiful and unspoilt islands. during your technical scuba diving course you can survive in basic accomodation for as little as 200 baht per day, right on some of Thailands most stunning beaches. Thailand is the perfect place to learn technical scuba diving, particularly the island of Koh Lanta, located in South West Thailand, home to the best scuba diving Thailand has to offer. If you choose a technical scuba diving course with Planet Tech, you can currently choose from DSAT and TDI technical scuba diving courses. Whats the difference? Basically not much - both certification agencies certify you as in technical scuba diving, the only difference is that the courses vary very slightly in skills performed and knowledge given. TDI have been around for many years (its the oldest technical diving agency there is), providing quality courses in technical scuba diving. TDIs diving courses are very flexible, and allow the instructor to throw in as many diving skills as he wishes (as well as the core diving skills required), to ensure that the diving skills of the student are of a high enough standard. The theory portion of the TDI technical scuba diving courses are also very flexible, with classroom presentations required to be given by the instructor. The TDI course book gives vital information, but most will come from the instructor. TDI technical scuba diving courses are very well tried and tested over the years and have proved to be some of the best technical scuba diving courses around. If you choose a DSAT technical scuba diving course you will have a manual that follows PADIs excellent past record in quality training materials. the DSAT tech deep diver manual is extremely comprehensive - so much so that if you choose, you can self study the entire theory portion of the course. If your knowledge reviews are suitable then the only part of the course you need to spend in the classroom is the exams - leaving you more time for diving! Both DSAT tec deep exams are very intensive, and leave you with a wealth of knowledge about technical scuba diving. The diving part of the course again follows PADIs track record, providing a rigid and well structured diving course. TDI technical scuba diving courses: TDI ADVANCED NITROX TDI DECOMPRESSION PROCEDURES TDI EXTENDED RANGE TDI TRIMIX DSAT TECHNICAL SCUBA DIVING COURSES: DSAT TEC DEEP LEVEL1 DSAT TEC DEEP LEVEL2 We also provide guided technical scuba diving for deep air and trimix divers at Thailands premier divespots - Hin Daeng / hin Muang / Koh Haa and the Similans - private charters available on request.
