Free divers tend to break a lot of cave diving rules.
One of the rules isn't about accident analysis, but I believe full cave divers are required to have a minimum of 71.2 cubic feet of gas to start a cave dive. Lungs cannot hold that much.
Cave divers are required to turn after using 1/3 of their gas source. If you have no gas source, you cannot use 1/3 of it, so you don't enter the cave.
Cave divers carry one primary and two backup lights. Most swimmer's don't have two backup lights in their pockets.
Cave divers run a guideline from a safe exit point. Did this free diver run a guideline?
A member of the media contacted me via Facebook, likely because he found connections between myself, UCF, the scuba club at UCF, and cave diving, via a search. I let him know some of the rules of cave diving, and what rules this man likely broke.
Never met the student. My thoughts and prayers go out to those involved, but my sentiments remain unchanged: only trained, equipped divers belong in a cave. If you don't have training or you don't have gear, or you don't have either, stay out! If you violate the most basic of rules and you die, you have only yourself to blame, and this death is most tragic because it was completely, utterly and perfectly avoidable. Those are the worst kinds. Preparedness is no accident! I hope people will learn from this death so we don't have a repeat. Stuff like this is what keeps me up at night, I've seen too many people die in caves for absolutely no reason, and I hate it!
