I have been to that site twice , first time about 20 years ago as part of the diving course. I remember one of the exercises was to go to higher depth and do math exercises to prove that our thinking was not impaired due to the depth.

For sure that site was not branded as deadliest in the world, but already back then dive masters told us about people who lost their lives there.

Diving seems like one of the recreational activities where it is easy to end up doing something much riskier than you intended (another I'd say is alpine hiking): 1. Being able to easily sign up for a dive at an all-inclusive resort makes it seem more 'fine', you get a false sense of security that you will be taken care of. 2. Dive shops tend to be fairly relaxed with checking if someone is properly qualified to go o…

I'm an avid diver and I completely agree. My Open Water took place in a hot spring with extremely low visibility. The goal was the cert it wasn't skill mastery. My next dive was the Great Barrier reef where boats just drop you off and you can get a guide or dive yourself. We irresponsibly dove by ourselves, exhausted all our air, and came up (skipping a safety stop) realizing we were a considerable distance from the boat. It's obviously our fault for not being safe but we definitely didn't have the necessary fear in us for our skill level.

I think PADI should be emphasizing that your first 20 dives or so should be with a guide never exceeding 60ft. IIRC, a lot of the course material for Open Water is about shore diving with a buddy by yourselves.

I had a similar experience at a tourist destination island in Australia. We went on a dive with just a couple of meters of visibility, with a big group holding on to a anchor chain. I couldn't see the dive instructor and I couldn't equalise my ears. Everyone kept going and I basically just stopped at about 10 meters down. It just wasn't worth it, especially given the ear pain I had for weeks afterwards.

As a counterpoint, I did another "introductory" dive at another Australian island a few years later, and it was beyond amazing. Prettier than any wildlife documentary I had ever seen. Incredibly attentive, patient, and professional staff, etc...

Earlier quoted context omitted.

The two biggest things with alpine hiking are probably weather and not turning around when you should. (I could probably add just being grossly ill-prepared like lacking map and compass and perhaps depending too much on electronic gizmos.) Over the holidays I was reading a book about a winter fatality on Mount Washington a few years back. The person was actually very well-prepared and fit. And even had some big mount…

Trails in the Alps in Germany or Austria can be tricky precisely because they are fairly well marked and signposted. A red route can be a 'walk in the park', nicely trodden path with a steep gradient in places, or include bits that are quite exposed with a danger of falling. As a complete amateur, it is easy to end up on a riskier route than you expected, as it would not even look remotely risky until you are half-wa…

Yep, this literally just happened to me here in Switzerland. An "easy" route at around 2300m which was great - a nice wide, cleaned road around snowy areas. And then suddenly a steep descent with 30+ cm of frozen iced snow. Without proper equipment, that would be extremely dangerous and even with equipment is was far outside the comfort zone.

Not a diver myself but my best friend is (he is also an instructor as well as cave/shipwreck diver and he has also worked for a dive center with a lot of tourists). I remember him telling me that diving in shipwrecks(or caves) requires additional certification, so I assume that those who have only the first/second star were not allowed to join (especially in a trip by an all-inclusive resort). What you describe sound…

Both caves and shipwrecks are allowed with Open Water as long as you are within a certain distance from an opening and natural light.

Idle speculation, perhaps a diver could answer - could it be that the reef forms a kind of natural solar pond, leading to an unusual osmotic (and therefore density) gradient? Thus resulting in divers suddenly dropping like a stone when they hit a certain depth? The Red Sea is one of the saltiest bodies of water in the world.

As a diver descends, they have to add air to their BCD (Buoyancy Control Device) to maintain neutral buoyancy (and release air when they ascend).

Without that compensation step, as a diver descends their buoyancy becomes increasingly negative.

Add a level of narcosis for descending below 40m, mix in some excitement/stress, and some equipment configuration issues (e.g. too much weight), and the task-loading can cause some people to forget/skip routine techniques such as adding air to maintain neutral buoyancy.
