Decompression Diving Course (SSI)


Decompression Diving

Are you interested in learning how to extend your dive beyond the traditional no-decompression limits? Do you want to understand and use more of your dive computers features? Then the SSI Decompression Diving Specialty is for you!


This specialty course will teach you how to dive beyond the no-decompression limits. You will learn to plan and conduct dives to a maximum depth of 40 meters with limited decompression using your own recreational total diving system and a single decompression cylinder. You will learn and practice how to effectively use your dive computer features, including switching gases, gas integration, time-to-reserve and time-to-surface. Using these computer functions will become second nature, enabling you to safely conduct dives with limited decompression without hours of dive planning.


Upon completion, you will earn the SSI Decompression Diving Specialty certification and be able to explore stunning deep dives sites without being restricted by the traditional no-decompression limits. The opportunities to expand your diving adventures have just got bigger.
