I’m not proud of this dive, or of how close I came to a less auspicious outcome. But I’m willing to air my appalling performance in public in the hopes that each of you will reconsider just how well you will perform in an emergency, and how well you’ve planned for that emergency. Keep thinking, slow down, and allow yourself huge reserves of gas. This is particularly important on bigger dives, but equally important on even the shortest one. I hope that sharing this experience will change someone’s behavior enough to allow them to survive a dive that would otherwise have killed them.
