Ali Lawrie wrote;. ****** Most importantly when asked if they had breathed from the reg BEFORE submerging the first and second stage they looked blank and said "YES". From experience, buddy's of mine, and I have learned that this is crucial. If you submerge the entire reg in the cold water prior to testing it then the chances of freezing are greatly reduced. Does anyone else have any comments on this procedure. It seems to be little known amongst the diver's I have met at these revolting quarries. ***** I would have thought this would be common knowledge with cold water divers, only to breath of the req when submerged, and definately not on the surface before the dive. Also once pressureised not to purge the valve whilst on the surface.
