Currently it's happening more and more that people are getting in situations which if something would happen could easily spiral out of control. Luckily not often something happens, which in itself is a bit of a problem because it enforces the believe that they are doing fine, and are safe (normalisation of deviance).
In this situation it was a very new diver (14 dives in 5 years in my eyes is really a beginner diver because most of these dives from his certification have already been long forgotten), who maybe overestimated his experience, overestimated his tools to compensate and manage issues (police officer?) or may have realised but wanted to do the dive (pinnacle dive) and relied on someone else to keep him safe (trust me dive).
People are pointing towards the diveshop, DM, his certification or the level and content of current courses. But that's not the issue I think. I see the same happening with technical divers as well, who have good skills, but find themselves also over their head in situations which can easily become unmanageable. Good tools (good divelights, good regulators, computers, scooters, rebreathers), and a rapid progression in certification (from OW to full technical cave and trimix diver in 3 years), can put you in spots where you really shouldn't already be.
Reason for this is simple... we know what we want and we want it now. We searched the internet and are visiting BC and this race rock thing sound incredible looking at the youtube clips and the pictures. I WANT THIS (to also show off on social media). Same goes for technical divers who see pinnacle divers do pinnacle dives and WANT THE SAME... and NOW. Pushed on by social media and the fact that we want to show off. Not realising the effort and steady improvement and baby steps needed to get there.
I myself wonder about this as well... Am I falling in the same trap. I'm getting to a point where I'm doing big dives (for me)... is being 2 km in a cave a good place to be in with 130 cave dives? Is doing a 30' bottom time 90m dive a good thing to do with 120 trimix dives? I'm not sure... been diving since 1990 but only tech diving since 2010. but I see other technical divers doing the same with much less... Anyhow this is going far off topic.
In any case I do think that there needs to be some space in diving courses to communicate the above and make aspiring divers aware and give them tools to self evaluate their experience vs the dive they want to make. This and personal responsibility will hopefully reduce incidents and accidents in the safe sport that diving already is.
