Price: 39,500 THB

The PADI Tec Trimix 90 course is the follow-up for the Tec 50 or Tec 65 course and can be run concurrently to the Tec 65 course at Kiwidiver in Phuket Thailand. The certification is the final stage in the PADI Technical Diver open circuit path. It is designed with deep exploration in mind and this class extends on the Tec 65 course extending your range to a depth of 90m using hypoxic gases.

The PADI Tec Trimix course prepares the extreme diver to further explore the world of technical deep diving and introduces divers to the use of travel gases and team protocol for deep Trimix dives beyond 65m. During the course, you’ll make dives as deep as 90 meters however the methodology applies to dives well beyond that. As you gain experience with the skills and procedures learned you will find there are few limits.
