Hi. I'm David Woods from Orlando FL. I have developed a more efficient swim fin which makes it easier to get around under water. That, of course, saves air allowing you to stay down longer. There is a thread in the classifieds http://www.scubaboard.com/forums/cl...r-swim-fins-stay-down-longer-less-effort.html where you can learn about how they work and how we hope to get them to the masses. If you want longer dives check it out.
