The Course

To access and fully explore many advanced dive sites, especially shipwrecks, divers must make stage decompression stops. Even for “recreational” sites in the 30 – 40m range, additional time beyond the NDL may be required to achieve dive objectives. For deeper dives, stage stops will be required for anything more than the most brief “bounce” to depth.
As with most things in life, we learn to balance risk and rewards. When you decide to exceed the no decompression limit, risk increases. This course is designed to provide information, familiarity with equipment, skills, and experience that will help you to manage that risk and reduce it to an acceptable level.

Course Content

Untitled-2This course will teach you the procedures required to plan and execute stage decompression dives utilizing 2 or more hyperoxic gases (ean50 and either ean80 or oxygen recommended) for decompression. Technical diving students will be introduced to advanced decompression theory and how divers can benefit from maximizing the “o2 window” during decompression.
The dives must have been made to depths between 30 msw and 50 msw, multiple decompression stops must be made in each dive, and the dives must be logged in the SSI techxr logbook.
