BSAC Accelerated Decompression Procedures (ADP)

BSAC’s Accelerated Decompression Procedures (ADP) course is a great way to extend your nitrox diving skills, by learning to use

oxygen-rich mixes to improve the efficiency of decompression. It encourages you to make informed choices about your diving.

It is a stand-alone course that also complements the Twin-set Diver course.

Using oxygen-rich decompression gases has changed the way I dive and has enhanced my overall diving experience.
I can now extend my dive times knowing that I can do accelerated decompression stops more safely.

- Simon Fitt-Stirling, Mid Herts Divers

Accelerated Decompression Procedures (ADP) introduces a qualified nitrox diver to the use of oxygen-rich decompression mixes

to achieve optimum off-gassing at deco stops, and promotes self-reliance within buddy diving.

You should also have 20 or more logged dives as a Sports Diver, including depth experience to 30m.
