What is the primary focus of the SSI Deep Diver specialty course?

The primary focus of the SSI Deep Diver specialty course is to provide divers with the skills and knowledge necessary for safe practices when diving beyond the 18-meter mark. This depth introduces divers to challenges such as increased pressure, reduced visibility, and different gas consumption rates.

The course emphasizes planning deep dives, understanding the physiological effects of deeper diving, managing potential risks, and utilizing appropriate dive tables or computers. By being trained specifically for these conditions and learning to address them effectively, divers can enhance their safety and enjoyment while exploring deeper underwater environments.

The other options, while related to diving in some way, do not encapsulate the essence of what the Deep Diver course aims to achieve. The focus on deep diving specifically distinguishes it from basic swimming techniques, equipment introduction, or instructor certification, which are different areas within diving education.
