Here is video of Kasey and Tilley's successful bail-in skill in Tallahassee SCUBA instructor Gabrielle's open water class. People often wonder why we would make students jump in the water without any gear on then assemble it under water. The bail-in drill encourages problem solving under stressful circumstances in SCUBA. When people are able to stay calm, it helps them better manage any problems in the diving environment. This is a required skill with SCUBA Educators International (SEI), formerly YMCA.
