I met Gary back in 92 or 93 when I first started researching wrecks for my "Histories & Mysteries" book. At the time I was a novice researcher and was basically trying to pick my way through the process using bits and pieces I had picked up along the way.
Gary was one of several established wreck writers (another was Ellsworth Boyd who was also extremely helpful) who I contacted and asked for advice. He helped me tremendously, not only with advice and encouragement but even a bit of actual research. We corresponded quite a few times and when he was in town he stopped by the house and we shot the **** for awhile. Extremely knowledgable and very unassuming (i.e. not arrogant). All in all a damn nice guy.
These guys taught me, among other things, the primary lesson in wreck writing, never believe anything without documentation. Many, even most, wreck writers accept what they're told as fact and end up writing fiction instead of history.
Anyway, as to the diving practices....
When reading Gary's wreck diving guides one should keep in mind the standard practices of the time when they were written. "Advanced Wreck Diving Guide" was published in 1988. Guess what we were ALL diving then? Air. "Ultimate Wreck Diving Guide" was published in 1992. Guess what? Very very few were diving mix then. IANTD was still IAND. Billy Deans in Key West was experimenting with trimix but it certainly wasn't commonly available, nor was the training. Mostly we were all still doing deep air although alternative deco gasses had come into fairly common usage. We were using them in the Keys, Gary and his bunch were using them in Jersey.
In 1998 "Technical Diving Handbook" was published. It was essentially a rewrite of "Ultimate Wreck Diving Guide" with the addition of...... MIX. The way I read the book, the virtues of mix were highly touted over deep air. Also discussed in a positive manner were the best technigues of penetration available at the time, DPVs, liftbag deco techniques and other things that we still use today. The buzz word then, as it is now, was redundancy.
Sorry but I don't see the terrible things that some of you seem to see. Sure, air diving is discussed, lots of folks still did it then. Matter of fact, lots of folks do it now. It's not touted as the be-all-end-all, just as a fact of diving life, which it still is for many people.
I think of Gary as one of the pioneers of deep wreck diving. I also think of him as a friend. I think he's still one of the best and most experienced wreck divers in the game. There are some guys building excellent reputations and doing extremely exciting dives like J.T. Barker in Virgina and the AUE guys in Florida but I think Gary still sits in one of the top spots.
Do I advocate deep air? No. Do I do it? Maybe.
