D.I.R III audio files.

The DIR III video was made in '99 by George Irvine, Bill Mee and Dan Volker but never officially released.

It talks about about basic diving with a single tank setup and how it relates to technical diving. A great deal of this information is also really important to be able to understand some of the more intricate details of DIR diving and equipment.
