EnviroDive Services, the company that developed the Nitrox Stik, originally provided the Gas Blender training for PADI, and wrote the PADI/DSAT Gas Blending Manual, just published an online Gas Blending Manual, "Blending Oxygen Enriched Air". Lots of great information in it at a great price, only $7.99. Downloads to you as a PDF file. I thought folks who read this forum might be interested.
