The technical diving curriculum from SSI. Maybe you are already an SSI diver or an SSI Dive professional. Do you want to stay down a little longer, go a little deeper or explore a little further? If so, the SSI XR and TXR Range of Programs is exactly what you are looking for.


SSI Extended Range programs are designed to take your diving to the next level. Whether you are looking for the excitement of deep diving, going beyond recreational diving limits, significantly extending your bottom time or enjoying the thrill of exploring deep reefs, wrecks and caves, Extended Range provides the training and experience necessary to complete your new adventure with confidence and skill.

Extended Range diving will open up a diverse variety of aquatic environments, increase your dive depths limits, extend your bottom times and train you on new procedures. Academically you will advance your knowledge and understanding of principles, procedures and theories specific to diving safely with a decompression ceiling. You will adapt your existing equipment or be introduced to new equipment concepts and the technically oriented dive rig. You will also learn and master new skills designed to enhance your safety and enjoyment using this new equipment design. During your program your instructor will cover everything from supreme buoyancy, propulsion, equipment management and effective decompression.

Throughout the program you will increase the knowledge, skills, equipment and experience to “extend your range of diving” in every sense of the word.
Whatever your current level of training, Extended Range Diving will challenge and thrill you mentally and physically.


SSI´s Extended Range programs form a bridge between Recreational Diving and Technical Diving. They are designed to allow you, the recreational diver, the chance to enter the exciting world of Extended Range diving without necessarily having to dramatically change your existing diving philosophy. These programs simply enhance and build upon your existing knowledge. They provide the components that will allow you to use the different gases, new equipment and skills necessary to complete limited decompression schedules.


SSI has developed specific training materials: exciting, cutting edge manuals with review sessions, specific DiveLog inserts and underwater slates. All courses and training materials have been developed by industry professionals with decades of extended range and technical diving experience.





As with all SSI programs Extended Range is designed to fit your schedule. You can take each program individually or take them all in one program. Training is flexible to match your goals and objectives. It’s menu-based just like our recreational programs.
