I’d argue much safer as your upper bound is not an air reservoir strapped to your body, it’s food/water …or in the event that shit really hits the fan, how fast you can secure a wound.

Generally speaking, these are rare events in both sports but one allows much more time for rescues.

"Some of the best diving I've ever done is snorkeling in Cancun..."

You're on the surface, generally with a life vest, don't have to worry about running out of air, generally the guides inter-communicate and take you to hot spots of fishes or turtles or whatever... tropical warm water. Biggest difference is access to air rather than having to be "self-sufficient".

What about the weird gases that can be in caves? Or just gravity dropping you down a hole? Sounds pretty dangerous.

I recently took a cave rope climbing technique course, after being comfortable with rope climbing in other disciplines, such as climbing, rope rescue and glacier rescue.

The bolting techniques used in caves are fucking terrifying. They work, but they are terrifying.

The strapped air reservoir could come in handy for when it rains...
