cave are different and you can ajusted yourself.

I dive mexican cave, never dive florida. the average deep is around 17 feets for most of my cave dive. I dont have a backup computer and I still feel safe.

depending of the cave configuration and the snorkel people around I sometime leave my primary reel in my car.

But there is no flow in our cave so I always take rule of 1/3 or rule of 1/4.

you can ajuste yourself in a way that it still safe for you.

I think no one seek to die
