About this course
Tec 45 Trimix Instructor
The Tec 45 Trimix Instructor course is a professional-level program for experienced technical instructors ready to extend their teaching into helium-based trimix diving. Run over an intensive week, it qualifies you to teach the full early TecRec pathway, including Tec Basics, Tec 40, Tec 40 Trimix, Tec 45 and Tec 45 Trimix Diver courses.
Because candidates arrive already holding significant technical qualifications and experience, the course focuses squarely on teaching ability rather than personal diving skill. You will work through detailed knowledge development on trimix theory and PADI TecRec standards, then move into supervised teaching practice, presenting knowledge sections and running confined and open water training dives for your fellow candidates.
Assessment covers your ability to plan lessons accurately, brief and debrief technical dives clearly, manage gas and decompression planning discussions with students, and maintain the rigorous safety culture that technical diving depends on. Instructor trainers and evaluators give direct feedback throughout, refining your teaching until it meets PADI's exacting standards.
The course concludes with the Tec Diver Trimix Instructor Exam. Pass, and you join a small, specialised group of instructors qualified to guide the next generation of technical divers safely into deeper, more demanding diving.

“🌊 IDC No. 8 – April-May 2026: AMAZING! 🌊 An incredibly intensive course that truly prepares you to become the kind of instructor you wish you had when you first decided to breathe underwater 🤿 It lasted nearly a month online and 10 days in person.💪💪💪 You need to trust the process, because the program is designed not only to teach diving skills, but also to help you grow into a more professional, confident, and responsible person 💪 During these 10 days, you’ll be so focused on learning and improving that you probably won’t even have time to take photos 📚🔥 The entire IDC Sardinia staff is always there for you — guiding, supporting, motivating, and helping you through every challenge. They seem to have a sixth sense for knowing exactly when you need encouragement, and they won’t let you give up, even when the summit feels far away 🌟 And don’t worry… there will also be moments of…”Greta ValotiSardinia · Google review★★★★★
“I just did my IDC with IDC Sardegna and it was the most amazing experience in my life. I love all of the staff with all my heart. The support, the training, the organisation and in generall every day was structured perfect. It was a challengig time, but I fully enjoyed it and was able to do a big step in my diving live. Special thanks to the Course Director Luca, who is one of the most inspiring persons I met in my whole life. Lets see what time does, but if I ever gonna do a contiuing education I will do it with him. Grazie”Simon SablotnySardinia · Google review★★★★★
“I did the IDC with them and everything was truly fantastic. They're professional, helpful, and ready to help you both with the course and if you have any issues with the equipment. They truly take care of every detail. Luckily, I don't have to do it again 😄 ✌🏼, but if I did, I'd definitely choose them again.”Christian FalcettelliSardinia · Google review★★★★★
“Becoming a diving instructor has recently become my biggest dream in life :) And this dream has finally come true, largely thanks to the wonderful team at IDC Sardegna, who shared all their love and knowledge of diving with me in the best possible way! I can only recommend that you take an instructor course with them so that you too can join this wonderful world in the most beautiful way possible 🙂”Enzo MenichiniSardinia · Google review★★★★★
