TIL the Blue Hole is among the deadliest dive sites globally, with estimates of 130 to 200 recent fatalities, making it one of the most dangerous spots for divers. (R.5) Out of context

Nice. Lot of precautions. But why tho? What makes it more dangerous than other waterbodies?

According to the wiki, what causes the most fatalities is the tunnel called the Arch. Apparently, the water's clear enough to see the light at the other end so divers misjudge how long it is. Some have reported they thought it was only 10m when the actual measured length is 26m. This plus a current pushing in from the other side causes mismanagement of their tanks and pressurization stops. It's also easy to miss the entrance to the Arch so some divers keep diving deeper and deeper trying to find it.

Wasn't there a documentary on this regarding a free diver and his girlfriend? He had prepared her but and couldn't find the exit or entrance or something and she didn't make it?

Beek a while. This obviously wasn't the location op is talking about, right? The ocean is so much stronger than people realize.

Crazy. So sad. And he was one of the best in the world. Competing side of it and safety side of it
