Why would inner-tube rubber degrade more quickly in fresh water as comapred to salt water?
I am not a materials expert, but the water in the cenotes sometimes has sulphur layers and bacterial layers in it. I don't know if thats it or not.
Couple that with the fact that the tanks are often stored in the sun, and when us "tourists" go cave diving, we are mostly using rentals which take a lot of abuse and having an extra way to secure the second stage when you are 2 stages back in the cave makes a lot of sense.
