Decompression Diving

 

There are many reasons why a diver might decide to learn decompression diving. Maybe there is something to explore a little deeper than the recreational dive limits allow. Perhaps the challenge of learning something that requires a good level of skill is appealing. One thing that will certainly happen is that you will become a more competent and safer diver.

 

The theory for decompression diving is comprehensive, yet interesting and constantly developing. Moreover, as decompression theory tries to understand and explain what’s happening to your body during a dive, it’s useful information for all divers.

 

Please note that I am not actively teaching at the moment. However with each course description on this website, courses are outlined as I would teach them. This will give you a better idea of what you should expect when training with any instructor.

 

When teaching any course, the first thing I would do is assess the student’s current level and go through the skills and procedures that they learned on previous courses. Then we start getting into the dive planning, risk management and diving procedures. We cover physiology, risk management, team protocols, skills, emergency skills, and equipment.

 

We spend a lot of time on dive planning and gas management, and practising following a dive plan and decompression ascent procedures. As we progress through the course students are task loaded and given problems to deal with during the dives. This is to make them really think about what they are doing, another step on the road to competence.

 

We do more dives than a standard course at this level- 6 dives minimum and 8-10 dives preferred. This is to allow greater progression, and also to help students to better retain what they learn.

 

Training options

 

You can do deco training with TDI, Raid, SSI XR, PADI, or IANTD. The Raid Deco 50 incorporates trimix, whilst TDI’s decompression procedures uses air or nitrox for backgas. TDI decompression procedures certifies you to dive to 45m (150ft). Raid certifies you to 50m (165ft).

 

With Raid, if you haven’t already done a foundation course in sidemount or a twinset, the learning curve is just too steep in the time allowed. Do an entry level course and then get some experience before undertaking any of these courses.

 

 

During my training courses, students learn decompression diving, regardless of which agency they choose. The laws of physics do not change depending on what a dive agency says. I teach the same procedures for all courses. The only exception to this is the use of trimix on the Raid course.

 

Once the decompression course has been completed, my advice is to go out there and enjoy diving at that level. Build your experience before thinking of advancing further with trimix or CCR.
