SSI XR Programs

SSI’s Advanced level XR Programs are technical diving, challenging the diver with multi-stage decompression, advanced failure management, plus supreme trim and buoyancy.
When participating in Technical Wreck Diving and Full Cave Diving, you will learn the ultimate in overhead environment techniques. Because of the nature of these programs, your training will be incredibly thorough and exciting. Nothing is left to chance and all bases are covered. The high level of knowledge and skills are taken a step further allowing you to push not only traditional diving limits but also your own.
This is the zenith in diving!

Once you have completed your training you will be ready for all of the challenges of technical diving.

Extended Range

This program qualifies you to dive to 45 meters using nitrox mixtures, and 25 Minutes of accelerated decompression using oxygen as a one stage decompression gas. The program can be completed only by using a wing and a full twinset.


Extended Range Trimix

As with Extended Range this course allows you to dive to 45 meters and 25 minutes of accelerated decompression time using one stage decompression gas (oxygen). In addition to using nitrox, you will be qualified to use limited trimix with a minimum oxygen content of 21%.
Extended Range with Trimix is specifically designed to reduce the risk of nitrogen narcosis for deeper diving.


Technical Extended Range

This program qualifies you to dive to 50m when using Air or 60m when using Normoxic Trimix (min 18% Oxygen content) two stage decompression gases will be utilized for this program. The program can only be completed wearing a full Extended Range total diving system.


Hypoxic Trimix

This is the pinnacle of technical diving. Here you will use all the knowledge, skills, equipment and experience from all of your previous training and push your limits to the extreme. There are two pathways; one takes you to 80 meters and the other to 100 meters using the same full Extended Range total diving system you mastered in previous programs. However, you will now use a minimum of three stages for decompression and travel gases.


Technical Wreck

This program allows unlimited decompression wreck penetration to a maximum depth of 60 meters (during training). Like the other overhead programs, the training required for this type of diving is overhead, high level buoyancy control, finning techniques, laying line and the proper use of a light. You will also learn about a lost line, lost light and lost diver procedure.

If wrecks are your passion then this program is for you. The program can only be completed wearing a full Extended Range or Technical CCR total diving system.


Cave and Full Cave Diving

Your entrance to the subterranean world of cave diving will come from the SSI Cave Diving program. Cave will allow penetrations on a single line with basic navigation. You will learn techniques to deal with problems in this most unforgiving of environments. Safety is the number one concern and you will increase confidence by spending hours in the environment with your Cave Instructor. Once you are comfortable, SSI Full Cave Diving allows complex navigation and you learn how to traverse, jump, tee and gap within the cave system. You will learn even more about a lost line, lost light, gas sharing and lost diver procedure. The Full Cave Diving Program is the highest level overhead environment program, providing all the tools needed to be a true explorer!
