assistant: G'day Lee,
In reply to your message of 19 August 1995
Thankyou, just a pity that some of my comments were chopped off. :)
Yes, the more experience one gets, the more comfortable one feels and the
level of anxiety drops off. The rate of breathing slows and you use less
air. Next time you dive with a group, watch the rate that the other
divers produce bubble, the newer divers or ones with bad habits tend
to produce a lot. :)
Well, the idea of diving isn't to sit on the bottom and conserve air, the
one that has the best dive is the one that sees the most interesting
things in the time allotted.
<grin> Yeah, and when you ask them if they saw the huge cuttlefish....
That's something else to look for, the way in which divers use their fins,
some use the most inefficient leg action it's amazing that they actually
go forward. The flutter kick, after many trials, is still the best kick.
Oh, here it is.^^^ <chuckle>
But aren't we all supposed to surface with a recommended amount of air
left in our tanks for just that reason. Plus all the practice with buddy
breathing etc, why not just get a bigger tank?
Of course unplanned problems will occure, but if the dive is planned, the
emergency will occure within a known time frame. The amount of time used to
manage the situation is the problem. What happens when you drain the pony
bottle? Same situation. If a diver runs out of air, giving a pony bottle
may complicate the problem, as the diver could panic and make a rapid
ascent to the surface. Buddy breathing not only helps to control a
situation but gives the troubled diver security knowing someone is close
and is helping.
Taking a pony bottle as an extra level of safety is a lot like taking
a powerhead handspear with you. It can make one become over confident
and complacent. "I'm not worried about consuption because I have this."
And the onus is on every diver to follow it. :)
