about DIR several years ago shortly after I got OW certified. As I recall I was a bit turned off by it due to the somewhat arrogant and bellicose way it was presented. This was through magazine articles and some discussions with folks who had been exposed to DIR.
I have learned the most about it from the many posts made on scubaboard. While some of the discussions here have been a little heated most of them have been interesting and informative.
