A3 features heavily in Issue 69 of Elevation magazine, and there are articles written by Dr. David Cameron (designer of the VG safety gears) and Russell Walker (Atwell M.D.).
The new edition is out now, and is sure to be a comprehensive guide to the A3 amendment. You can find out more about Elevation magazine at their web site.
If you don’t subscribe to Elevation magazine, don’t worry! We will put the articles on our web site in January.
