60' on O2 would scare the crap out of me. Especially if your OTU's are high from a long dive already. I have never had or been involved in an incident where most or all of the deco was blown off. I have had and been around people who have had some sholder pain etc. after a dive. I can tell you from my experience that going back in the water and going to a depth where the pain subsides and then slowly reascending doing stops at every 10' for a few minutes at a time then staying at 10-20' on 02 for an extended time definitely makes you feel better. I am of the opinion that the sooner you can get recompressed the better. I think TDI is teaching an in water recompression class now. What depth are they recommending O2?
I am not aware of a course by TDI, but UTD has one. That developed somewhat out of necessity, since they had several divers need to use it on several occasions at a remote location.
This article by Pyle and Youngblood includes a history of the different protocols, most of which limit the depth to 30 feet using oxygen. I have not seen any protocols anywhere at any time advocating 60 feet. Some of them suggest a PPO2 ranging from 1.4 to 1.6, which is even more restrictive of depth.
It seems to me that if you think you are going to use this procedure in your future, you should study the various protocols, select one, and have both the necessary knowledge and equipment on hand when you dive.
