Subject: Re: Solo Diving Article, NACD
I think some of you are missing the point of the "most important person"
concept.  Mr. Rennaker is just being honest about basic human nature.
When things are the worst we all revert to our survival instincts
despite the best intentions.  Recent case, the Jackson Blue incident
also detailed in the Journal (and let me emphasize that I am not sitting
in judgment of these divers),
three divers entered the system.  At maximum penetration they had a silt
out and lost communication with each other...they became solo divers.
Two of them were able to regroup attempt a search and then exit...the
third was left behind.  As the two exited their stress levels were
obviously elevated with self preservation being the priority.  When they
reached their safety bottles, three full 80cf  at 1000', neither diver
elected to pick up the bottles and go back in to search some more....the
thought of getting out was paramount and understandable.  In all cases
self rescue is better than buddy rescue and should be taught in that
order.
As for solo diving, it should be made as a cognitive choice not as an
outcome of circumstance.  The divers at Jackson had no intention of solo
diving, but for a time it occurred.  Mr. Rennaker's article eludes to
these types of scenarios.....swimming or scootering too far apart, loss
of visibility
without touch contact,  long one-man restrictions, stressed or task
overloaded diver....these scenarios are "solo dives" and should be
avoided if you are not prepared for them.  The other type of solo diving
is intentional, even if a "buddy" is in the water.  Small system
exploration being the best example.  It requires special gear, training,
and mind set.  Solo diving can and is being done safely on a routine
basis by a small number of experienced cave divers.  They just don't
advertise or promote the activity...solo diving definitely is not for
everyone, but neither is cave diving for that matter.
