I copied this over from the Homebuilders section because I figured more people might see it here:

Hey folks. I've just come across something really interesting. Now a few of us have been buying modifying and diving surplus Russian gear. Not just rebreathers but including rebreathers. Here is a website that came to my attention through work (I work for the Census of Marine Life) regarding Russian Diving expeditions to Antarctica. Please note that the diver in the pics is using what appears to be surplus military gear: drysuit, full-face mask, double hose regulator, and some rusty old double tanks.

Ha!! Who says that stuff is old and outdated. The Russians are still using it on scientific expeditions just last year.

Just a little something I thought some of you might be interested in.
