Tell you what though, as an experienced deep diver, I would not ever carry one - my redundant tank has between 5 and 40 times the capacity - and is usually strapped to my dive buddy's back. I have no delusion that there's enough air in one of those tiny tanks to get safely to the surface from 40 meters depth.Or just do what Lara Croft did in that Tomb Raider movie-- cut your hand, wait for a shark to swim up to you, punch it in the face, then grab its dorsal fin (because punching a shark in the face will make it swim to the surface). Presto! You're saved.
Heh, if you're breathing on SCUBA, more like "Presto! You're bent. Hope you enjoy a trip to the hyperbaric chamber, or emboli."
