Exte​nded Range

SSI Extended Range

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 a limited decompression schedule


All Courses have a minimum age of 18

XR Foundations

The SSI XR Foundations program provides divers with a workshop environment to improve their skills to a high level using the Extended range total diving system and procedures.

This program qualifies you to dive to 40 meters with 15 minutes of staged decompression using nitrox mixes up to 50%. The program can be completed wearing a single cylinder with either a pony bottle or a H/Y valve or a technical total diving system.



XR Diver

This program qualifies you to dive to 45 meters using nitrox and up to 25 minutes of accelerated decompression using one staged decompression gas (oxygen). The program can only be completed wearing a technical total diving system.

This course allows you to dive to 45 meters and 25 minutes of accelerated decompression time using one stage decompression gas (oxygen). The program must be completed wearing a full technical total diving system. In addition to using nitrox, you will be qualified to use Trimix with a minimum oxygen content of 21%. The Limited Trimix program is specifically designed to reduce nitrogen narcosis in the extended range diver.
