OXYGEN HACKER'S COMPANION

NOW AVAILABLE - THE BRAND NEW, EXPANDED, HEAVILY REVISED FOURTH EDITION!!!

What's new? A complete cosmetic redo w/numerous photos - $25 continuous nitrox mixer plans - $6 BC hose nitrox sampler plans and, if that's too expensive for you, a 75¢ no-regulator direct-from-the-tank sampler that makes everything else obsolete - Argon - Updated sensor info and analyzer plans - and hundreds of other minor updates and additions throughout the book.

 

Since its publication five years ago, the OXY HACKER has become a tech diving classic - the most quoted and relied-upon guide to gas mixing and handling in the real world, for diving, aviation and emergency use. Treading boldly where the tech agency manuals fear to follow, this is the only single book that covers it all, and gives you the information you crave.

"I really been meaning to write to tell you what a fantastic book the "Oxygen Hacker's Companion" is. Of all my diving reference books on the shelf, it's the most dog-eared and beat-up due to my constant reference to it. I've loaned the "Companion" to many friends, and as a testimonial to its value they have all purchased copies themselves. Keep up the good work, your book is irreplaceable."
- R.O.

"Any news on when the Regulator Repair/Maintenance manual will be available? I want one! I love my O2 Hackers Companion! The best How-to manual I've ever read! Been mixing my own NO2 and haven't breathed air on a dive since!." - S.G.

 

Some of the subjects treated:

- Where to buy, or how to make a nitrox or trimix mixing whip.
- How to mix your own nitrox and trimix without a lot of expensive gear.
