**SSI Technical Extended Range** is the next step in technical diver development following the Extended Range course. The program prepares divers to conduct more complex decompression dives to a maximum depth of 50 meters using air as the bottom gas and two decompression gases.
Training can be completed in either a Twinset or Extended Range Sidemount configuration. Special emphasis is placed on dive planning, multi-gas management, gas switch procedures, and the efficient execution of longer decompression schedules.
Who is this course for
- Graduates of the SSI Extended Range course or an equivalent decompression diving program
- Divers with experience in decompression diving and gas switch procedures
- Divers looking to further develop their technical diving skills
- Twinset divers
- Extended Range Sidemount divers seeking to expand their decompression diving capabilities
- Divers planning to continue their development toward Trimix diving
- Divers interested in advanced dive planning and multi-gas management
- * The program is intended for experienced technical divers with prior decompression diving experience. When completing the course in a sidemount configuration, a Sidemount certification is required, while prior completion of the Extended Range Sidemount course is strongly recommended.
What you will learn
- Planning and conducting decompression dives to a maximum depth of 50 meters
- Using air as the bottom gas and two decompression gases
- Planning more complex decompression profiles
- Advanced multi-gas management techniques
- Proper gas switch procedures
- Organization and management of multi-cylinder configurations
- Improved buoyancy control, trim, and propulsion techniques during technical dives
- Team diving procedures and communication
- Problem-solving and emergency procedures during decompression dives
- Planning and organizing advanced dives in either a Twinset or Extended Range Sidemount configuration
How we work
Training is conducted according to the **Sidemount Precision Protocol** methodology, built on precision, procedures, and the conscious development of diving skills. Whether the course is completed in a Twinset or Extended Range Sidemount configuration, special attention is given to proper equipment setup, multi-gas management, and procedural accuracy.
New skills are first practiced on land before being transferred into the water. Throughout the course, we use video analysis to evaluate diver positioning, technique, and procedural execution. This allows participants to receive detailed feedback and continuously improve their skills throughout increasingly demanding decompression dives.
Course schedule
The course begins with online academic sessions covering advanced decompression planning, multi-gas management, gas switch procedures, and safety protocols. The academic portion provides a solid foundation for the practical training phase.
Practical training starts with skill development and procedural practice in confined water or shallow training environments. Depending on logistics and scheduling, part of the course may be conducted in Poland, for example at Koparki Jaworzno, where the focus is placed on refining techniques, procedures, and preparing for deeper dives.
The final part of the course is typically conducted during a diving trip to locations that allow the full depth range of the program to be completed, such as Croatia, Egypt, or other suitable destinations. It is also possible to complete the entire practical portion of the course during a dedicated training trip.
