Cavern Course Skills: Zero Visibilty Air Share Practice in Confined Water

TDI Instructor Natalie L Gibb and her assistant Fredrix demonstrate a skill on a confined water line circuit: a zero visibility, air sharing exit.  During training, it’s important to prepare for the worst case scenarios, and this would definitely be one of them. Once you have a protocol to follow, even managing a situation like this one is simple, it just takes practice and a little muscle memory. Students taking the TDI Cavern Course will practice this skill first in the confined water, and then in the cavern zone.
