The decompression procedures course is an exciting step further into your dive career.
You can train in your properly configured recreational gear with just an extra stage for the deco gas. You will only need and extra regulator and stage rig and you can still join regular dive operation which is a great advantage.
If you already are an Intro to tech or Sidemount diver you can use this configuration with an extra deco tank.
You will get the best out of this training if you already are an Advanced Nitrox diver or if you combine Decompression Procedures and Advanced Nitrox.
These courses will be the foundation of all other technical courses.
