Open Water divers can then add Specialist Level 1 specialties (Buoyancy, Navigation, Night, Photography, Video, Marine Life and more), which can be added to or even included with the Open Water Scuba Diver course, or taken later to gain more actual diving experience.

Equipment Specialist
Develop the knowledge to maintain, troubleshoot and care for your own scuba equipment. This non-diving specialist course covers regulators, BCDs, cylinders, valves, exposure suits and accessory gear — how each component works, routine post-dive care, common field repairs and when professional servicing is needed. An invaluable foundation for any diver who wants to understand their kit, reduce equipment-related problems and dive with confidence.
