Decompression Diving

During your Deep Diver training course, you learnt about the equipment, gained skills and knowledge required to safely plan and conduct recreational, no-decompression, deep dives. 

Your deep diver training gave you access to a diverse new range of dive sites, that were previously out of your reach, including deeper underwater canyons, archways and towers plus artificial features like wrecks.

The limiting factor was no decompression, you simply followed the non deco tables and enjoyed your deep dives. Over time your air consumption decreased and you decided to take the nitrox course to extend your bottom time, quite often there were areas you could have stayed longer, but were still held back with the non deco element.

Using a Nitrox gas blend can increase your allowable bottom time, so long as you don’t exceed the maximum operating depth for the gas- But even the best nitrox mix, has relatively short bottom times for deeper dives.
This is hardly enough time to gain experience at depth, nor enough time to fully experience- the new underwater environment.

If you want to safely increase your bottom time, you must expand your training!

As global travel becomes more affordable and accessible, access to once-remote dive sites that push the limits of recreational diving, is now easier than ever. The expanded limits of decompression diving greatly benefits visitors of many historical or archaeological dive sites, which are located at depths between 30 and 45 meters.

Micronesias' Truk Lagoon, is a perfect example of one of these sites. Many of the wrecks in Truk are found between 20 and 40 metres. Even though these sites are accessible to qualified recreational divers, they are often very large— many wrecks are more than 120 metres in length.

Safely exploring the entirety of these wrecks, both inside and out- is nearly impossible without exceeding the non-deco limits.

One of the tenets of SSI training is to never exceed the limits of your training or experience. The diving industry recognises that there is a desire for decompression programs, that meet the needs of recreational divers, without requiring the rigours or training of extended range or technical diving.

The SSI Decompression Diving program gives you the additional knowledge, skills and experience to dive beyond the decompression limit, using the features of your personal dive computer, your recreational Total Diving System plus a single stage cylinder!

After earning your certification, you will be trained to plan dives using; 

  • A single decompression gas—  
  • Maximum of EAN 40 during training— 
  • Up to 15 minutes of decompression  
  • To a depth of 40 metres 
  • With an equally or more qualified dive buddy.

This training uses the same fundamental concepts as the SSI XR programs, which means that everything you learn in the Decompression Diving program is applicable if you choose to continue extending your range.


  • Minimum age: 16 years old.
  • 24 total dives

Have the following SSI certifications or an equivalent from a recognised training agency:
