SSI's new recreational specialty.

The SSI Decompression Diving Specialty will teach you how to dive beyond the no-decompression limits. You will learn to plan and conduct dives to a maximum depth of 130 feet with limited decompression using your 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 dive sites or larger wrecks without being restricted by the traditional no-decompression limits. The opportunities to expand your diving adventures have just got bigger! Decompression Diving enables you to dive beyond the no-decompression limits (NDL), utilizing a recreational total diving system and a single decompression cylinder (AL40). Upon certification, divers can plan and execute dives up to 130 feet in depth, with up to 15 minutes of planned decompression. The course covers gas planning, computer use to include switching gases, time-to-reserve, and time-to-surface functions, as well as skills needed to perform a decompression dive.
