TEC 45, Advanced Deep or Decompresion Procedures Course

This is the main course to get started with Decompression Procedures.

We also cover Physics (Henry's Law, Decompression), Physiology (Decompression Sickness), and learn about the different decompression theories, as well as dive planning with decompression and the use of software for its calculations but also will get into the the ability to manage time, depths, and safety during complex dives.

It’s an incredible course where we expand our comfort zone to 45 meters, a perfect depth for exploring a large number of wrecks and stunning walls.

The course can be done with Air or Trimix 25/25. If Trimix is chosen, an additional theory session is required.

AFTER THE COURSE

Upon successful completion, you’ll be certified to dive without direct or indirect supervision, to a maximum depth of 45 meters, using Nitrox as decompression gas (up to 100%).

You can then continue your progression with the next level:

→ OVERHEAD PROTOCOLS

→ POSEIDON CCR DIVER 30
