Recycled air apparatus

[Home.Brew]

I watched a show the other week on a husband/wife team (can't remember their names) that are pretty famous, by their count, in the area of underwater video and film. Their scuba equipment consisted of a large unit they would wear on their back that contained two ball-shaped canisters of air/nitrox, with a rather large circular filter, and the unit would recycle their expended air, enabling them to enjoy deeper bottom time. Sorry - but that's the best description I can give.

Any idea what this equipment is or where to look for it?

I believe you are referring to a re-breather. http://www.scuba.com/shop/product.asp?category=157&fromsearch=1&hashvalue=235001

Check out the rebreather section of scubaboard. Scroll down through the forums. You will run into it.

That would be it. Thanks much.
