The primary focus in scuba diving, over and above having a good time and seeing amazing things, is always diver safety, everybody wants to make it back safely and often the best way to do that is to call an end to the dive.
Anybody can call an end to a dive at any point for any reason, full stop. It’s as easy as that, but some divers do end up in trouble on a dive, either through peer pressure or that they just didn’t know any better, and hopefully this video might help prevent at least one incident and give some new divers the confidence to call off a dive, that might otherwise have a bad ending.
