Possible Reason for Dive Watch Bezel by: Anonymous
I too have searched the internet, and too, in vain for a suitable answer.
I'm a recreational diver, myself. To share with you further, I have noticed in resorts that intro dives (for non-certified divers) last about 15 to 20 mins; aside from the safety issue of leaving enough air in the bottle for beginners, perhaps it may have something to do with the saturation of nitrogen into blood over the 15min period of time?
Perhaps less than 15mins then nitrogen saturation is negligible? Then again, I know that is reaching hard for an answer because the nitrogen saturation is a function of both time elapsed AND pressure. Sigh.
Will appreciate any insight you come across. I, too, will let you know if I find the answer.
