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
