Certain SSI Specialty courses require a higher level of training to acquire the certification. These courses require a well-rounded understanding of the theoretical knowledge and a higher number of dives to reach the desired goals. The completion of these specialty programs requires a longer period of time than usual. This specialty course can only be combined with other specialties to a limited extent. Nonetheless, these types of certifications can be beneficial, as they provide additional advantages like extended depths, longer dive times, and even authorization to use specialized diving gear. We have classified the diving courses in question as Specialties II and provided an overview with detailed descriptions on this page.
