1. Theory
Decompression Theory: Understand the principles of decompression, including dive physics, gas absorption and the mechanics of decompression sickness.
Decompression Planning: Learn to plan dives with mandatory decompression stops using dive tables, dive computers and specialized software.
Gas Management: Techniques for managing gas supplies during decompression dives, including planning for contingencies and calculating gas consumption rates.
Dive Physiology: The effects of deeper dives on the body, including nitrogen narcosis and oxygen toxicity, and how to manage these risks.
Equipment Configuration: Understanding the necessary equipment for decompression diving, including redundant systems, decompression gases and specialized dive gear.
2. Practical Skills
Equipment Setup and Configuration: Familiarize yourself with the proper setup and use of equipment specific to decompression diving, such as stage cylinders in recreational or sidemount configuration.
Decompression Procedures: Practice the execution of decompression stops, including the use of different gas mixtures to optimize off-gassing and reduce decompression time.
Emergency Procedures: Learn and practice handling potential emergencies, including gas management failures, lost decompression stops and diver rescue scenarios.
3. Dives
Pool/confined water session: Conduct a shallow dive, applying the theoretical knowledge and practical skills learned in the course.
Open water dive 1: This dive will be planned within the no-decompression limits of the student’s dive computer or dive planning software.
Open water dives 2 and 3: Perform decompression dives with a focus on gas management and safety protocols. The total time for all required decompression stops on the back gas profile will not exceed 15 minutes per dive.
With the Decompression Diver certificate you will be able to dive with an equally- or more-qualified buddy. This course prepares you for further technical diving courses, such as Extended Range and further technical diving certifications.
If you have your own car, you can come to our dive center Ola Diving in Costa Adeje. In case you need to be picked up, please choose one of the options:
