TDI · Combined package
Adv Nitrox + Deco.
The two courses taught as one continuous programme. Bundle price, same depth of training.
What this
course is.
Two TDI courses, one programme, one team. Advanced Nitrox and Decompression Procedures taught back-to-back with a single instructor and the same dive buddy. Pace stays continuous, configuration stays consistent, and you finish certified to use gases up to 100% oxygen with unlimited decompression (gas-permitting).
Who this
course is for.
- Divers committing to the full step into tech in one stretch.
- Travelling divers wanting both certifications in one trip.
- Pairs and buddies who want to train as a fixed team.
