The first thing they added was emergency weight drop. In
this exercise, the student, while at the surface, drops her weight pockets to
experience the increase in positive buoyancy. It first, I thought this was a complete “duh.” Who doesn’t
know that if they drop their weights, even with no air in their BC, they will
rapidly become positively buoyant? Well, there is no teacher like
experience. I tried it on a couple
of recent students, setting up the scenario: You surface out of air, help is
not near, and you are exhausted, feeling panic rise. I instructed, in that situation, that their best course of
action would be to drop your weights. I reminded them that we talked about this
extensively in the classroom and they of course understood that they would
instantly be bobbing much higher in the water after this. To my surprise, after
they dropped their weights they commented in surprise, “Boy I had no idea this
would make that big of a difference”.
I believe that this exercise made an impression that will stay with
those divers and will better cement the option of dropping weights in an emergency.
They are less likely to be victims because they did not avail themselves of this
simple solution for buoyancy.
Another additional skill is responding to a loose
cylinder. Again, I thought all
divers will undoubtedly have this happen to them or their dive buddy at some
point in their diving careers, but this is something a diver can figure out on
his own. However, the pointers
that an experienced instructor can give students on how to remedy this
situation, as well as actually doing it underwater, can go a long way towards
instilling confidence in the divers’ own readiness to dive away from the
careful eye of the instructor. The
only thing I wish they would have thought of, would be adding the sign language
used to communicate the problem and solution. I plan to add that to my course, though.
Lastly for this blog, I will share the air supply awareness
skill. Students are required to
know their air pressure, without looking at their gauges, within 200psi when
the instructor asks them. How many divers think they can do that? Have you ever been surprised at the
amount of air you have in your tank? The point of this skill, obviously is to
ingrain a habit in the diver of looking at their gauges and being constantly
aware of where they at with their air. It is often the case that once a diver is
certified, he becomes lax, knowing that he will not have to “do tricks” for
anyone. This is where it can get
dangerous. The diver starts having fun, looking here and there at all the life
around them, enjoying the freedom of the underwater environment, until suddenly
he remembers his gauges and he may find himself low on air and far from his
exit point. Hopefully, this new batch of divers will have developed a healthy
habit of monitoring their air closely and they can enjoy all the things the
underwater world has to offer without lapsing into carelessness. It is in ever diver’s interest that the
sport maintains its exceptional safety record.
Next week I will share a few more additions to the PADI open
water program, and hopefully, even if you are an experienced diver I can draw
attention to a few skills you have forgotten about, or will find reason to work
on.
P.S. Don’t forget to check the web calendar and make plans
to join Team Manta this summer!
