Has anyone ever tried out those O2 safety systems that actually create oxygen through a chemical process? I saw one on Ebay and thought that it would be a great idea for our dive club. To clarify what this is, I am speaking of the emergency O2 for OUT OF THE WATER. Just thought it would be great so first I can have it in case an emergency did occur and second that I would not have to get it filled after I fly. What are your takes on it?
