I have over 6000 dives and teach technical and technical/advanced wreck penetration diving (
a skill-set and training near identical to full cave). Nonetheless, I
wouldn't enter a cave without completing the training specific to that environment and having received approval following appraisal by an environment-specific expert.
The more experience I've gained in diving, the more respectful of dangers I have become. I recognize that specific training; targeted to individual environments and activities, increases surviveability through the mitigation of hazards or the provision of options when hazards aren't avoided. I recognize that external validation by someone with specific expertise is vital in ensuring competency; as self-appraisal is prone to over-estimation for many reasons.
I've had friends who have perished diving, doing the same dives, the same activities that I participate in daily. I'm also ex-military and a veteran of Iraq and Afghanistan. I harbor no false illusions about the nature of death whilst trapped in an overhead environment, from drowning or from DCS. It's a ghastly way to expire.

Besides a few C-cards, what is the big difference between this incident and Marcie's? I mean besides the reaction of SB members.
One incident didn't include the death of a minor (
not an idiot, as one has suggested - but a child not deemed sufficiently mature to make the necessary decisions).
In other respects, there are similarities:
1) Over-estimation of competence.
2) Under-appreciation of hazards.
3) No training for given activity/equipment/environment.
4) No appropriate experience progression for the given activity/equipment/environment.
There are also differences:
1) I am not aware what warnings, if any, Marcia received. She certainly received 'enabling' support via the forums and friends. I wonder if the cave fatality received the same?
2) The diving industry / community is much more categorical about the need for overhead environment training, compared to drysuit training (
although the need for appropriate equipment training is nonetheless espoused by agencies).
