- I did my first emergency free ascent from 80' with no problem because
- every time I ascended from the wreck we were diving on (three times a
- day for 4 weeks before the incident) I did a free ascent "just for
- practice." I was damn glad I did when my reg finally self-destructed.
- I remembered the only thing I had to and that was to EXHALE. Luckily, I
- didn't miss any decompression stops.
-
- The second time was from 200' where I had run out of air and believe me,
- it was scary. Again, though, successful, because I had continued my
- practice to come up without the regulator in my mouth "just for
- practice" from depths as deep as 150' to my first stop.
-
- I would be interested in reading comments (not flames) pro and con on
- recreational divers practicing "just in case."
