There’s a good reason why checklists are used: they save lives. It takes little time to go step-by-step through a checklist, but it ensures that nothing critical is overlooked. A checklist is probably the cheapest piece of life support equipment a technical diver will own, but it will look after you, dive after dive.

See why some incredibly experienced individuals still rely on simple checklists to ensure their safety. It’s because of that mindset that they have been able to do the amazing things that they have time after time and still be able to tell their stories.
