This site was created to provide a good, free information source on the "black art" of mixed-gas diving. Amidst great controversy I put this site together to serve as a informational resource for diving with helium and related topics.

All suggestions and contributions will be appreciated and, if usable, added. If you see anything amiss or have some information to you would like me to add, email me at jimcobber@gmail.com.

I wanted this site to be low-overhead and friendly to all browsers, so I kept things simple.
