But scuba spelunking gives you the worst of both. Easy to get lost, easy to get stuck especially because you have a big tank on your back, if you let silt kick up its easy to get turned around and lost in the cave, and of course you also have a limited air supply.

At least you die faster. If I was in the position of the guy in the picture underwater I would just spit out my regulator.
Also if you have the tanks on your side and you never take them off to go through a hole you can be pretty sure that you can go through anything back if your remove them. Siphons tho, that’s a different story
