I recently found on line and personaly spoke witha representative about portable dives..Im not sure of the degree of benifit ,although I was told they do carry a 1.5 pressure rate, and a mini dive starts at 5,000 and they have payment plans,,I am considering this option after I do more research on [soft dives] verses solid dives,,But in my opinion, I believe alittle compressed oxygeon is better than none. They do make different sizes..But I was interested in the mini[enough to lay down in],to get the benifit,,,anyone on the board who has knowledge or expeinece with these ,please chime in,,,thank you
