YMCA, and I'm sure the other US agencies, have similar currency requirements.
Y instructors must teach at least 6 students each year, or earn a certain
number of continuing education credits (can't remember how many offhand),
or some combination of the two.

It's (yet another) incarnation of the Datamax Sport with more whistles and  
bells.  It has a user changeable battery unlike the Datamax Sport/Sherwood  
Source. I think it costs about twice as much.

Amazing how that nasty ol' DSAT model proliferates...

Hey there,

Looking for 3+ people to fill a charter this saturday from
pro divers in braintree.  Their number is 848-4990.  Destination
to be determined according to weather and divers.  There are three

The Aladin Pro and Sport both monitor altitude and compensate automatically. 
If you increase altitude, it will turn on.

Which makes for an entertaining trip.

We have about 22 people from our shop making a trip to CoCo View in a few
weeks.  I think 16 of them have Pro's.  They've started a pool for first and
last beep.  It seems that on an airplane (commercial) you have the potential
for going up three zones (according to "their" computations).  Makes for lots
of beeps and sometimes a freaked out cabin crew :-)

This depends upon how we are using it. For the pressure of the water
at depth (which seems to be what you are asking) fsw (gauge or absolute)
is common. 1 fsw is the pressure increase for each foot of depth in sea
water. 1 atmosphere = 33 fsw. For partial pressure of gases, partial
pressure of O_2 being the most critical, ATA is more common. For pressure
in tanks psi is all I've seen used, though I have heard of people using
bar because they had European gauges. Another difference is that in the
US tank capacity is given by the equivalent volume (at standard=1 ATA)
pressure tank when filled to working pressure (which is given
separately in psi), rather than the actual internal volume and the
working pressure in bar as is common in Europe. We would have to divide
to get the internal volume of tanks, which is seldom considered except
in rec.scuba. You would have to multiply to get the equivalent volume
at 1 ATA to know how much air you actually have. An advantage of the US
method is that when you are comparing the capacity of tanks, e.g. an
aluminum 80 (3000 psi) versus a steel 72 or 95 (at 2640 psi) or a Genesis
80, 100, or 120 (3500 psi), you don't have to convert because of the
difference in working pressure.

Nobody likes to see dead fish and broken reefs, but let's 
remember that hurricanes are entirely natural events,
uninfluenced by man in any way.  All sea life, including
fish and coral, evolved in an environment in which
hurricanes occur; they are what they are in part because
of hurricanes.  Hurricanes may not be much fun, and the
mess they make of sea life may not be pretty to look at, 
but they are part of nature, and part of the life of the sea.

This sounds, frankly, like she developed a shunt.  A shunt is likely
to increase the possibility of DCS.  Personally, I believe that this
is the main factor in the likelihood of repeated DCS hits.  I heard a
tale of an instructor in the Caymans who began to get bent in the pool.

	NAUI does offer a "deep diving" specialty course and, starting
	this year, a mixed gas specialty course.

	The Deep Diving Specialty course covers the depths from 60fsw
	to 130fsw, and so, may not qualify as deep (>130fsw) for some
	folks (NAUI does not sanction any instructional activity below
	130fsw -- national standard for recreational training). 
	
	The Mixed Gas Diving Specialty course covers ANDI (American 
	Nitrox Diving, Inc.?) Nitrox I and Nitrox II, and the course
	instructor must have successfully completed ANDI's instructor
	course.

	I'm afraid it's not so straight forward...

	While getting bent does increase the chances that an individual
	will get bent again, it does not always mean the end of a diving
	career (that's between you and your physician).  This is no
	reason to increase the risk getting bent by taking chances.
	The effects of getting bent are still unpredictable.

	It's interesting to note that, according to DAN statistics,
	repetitive diving and multiday diving are greater risk factors
	than depth.  Now, consider the kind of diving most people
	do on vacation (me too):
	
		4-5 days 
		3-5 dives/day 
		60-100fsw

	That's repetitive, multiday, *and* deep (>60fsw).

I rode an 18-wheeler from Miami to Homestead yesterday, carrying ice and water
for the devastated areas.  The traffic on the Turnpike and U.S. 1 is
unbelievable.  Rescue trucks and ambulances are having a tough time getting
through.  Even if they've lifted the travel restrictions on U.S. 1 leading to
the Keys I do not think it very prudent to try to travel there by car for
awhile.  There may be some flights to Key West out of Miami International, but
you will have to call the airlines to check.

After having seen the terrible destruction first-hand, I can honestly say that
this is one time the media cannot amplify the extent of the damage.  It is
simply more than you can take in with your own eyes.  The camera crews are
trying to show the expanses of destroyed homes and buildings, but they just
can't begin to capture the tremendous scope of damage and destruction in those
areas.  I thought we were hard-hit in Miami, but I've revised my opinion.  We
lost lots of trees and power, and some buildings.  Homestead and Florida City
lost EVERYTHING.

Again, the Red Cross, Salvation Army, and a host of other organizations are
taking donations of food and supplies and money.  The last I heard they don't
need clothing.  Please help if you can.

I was SSI certified and the instructor worked us through numerous 
decompression profiles with the tables in the classroom part
of the course.  He was very insistant that we never *plan* a deco 
dive (yeah right, after a year of regular diving, I was going on 
recreational deco dives with him), but should know what to do if 
we exceed the limits through emergency or accident.  The tables that
came with the textbook had deco tables on the back.  I don't remember
having any decompresion problems on the exam, however.  I have never
formally taken an advanced class, but have been diving regularly
with very experienced divers (most of my dive buddies are DM's or
instructors) for years now.  I have slowly worked my way up (down)
to fairly serious diving.  I think that it is irresponsible for the
certifying agencies to simply say stay out of deco profiles and
not teach the princples.  There's not really all that much to it
and it could save you a DCS hit.

    Very true.  However, these lifeforms are trying to survive in an
environment that man has pushed to the edge of destruction.  *Any*
destruction now, man-made or natural, can be devastating.  It is
unlikely that reefs affected by the storm will ever return to their
earlier state as mere survival has become taxing on these creatures.
Man is simply changing things too fast for ocean life to adapt and
evolve so that we are slowly choking the life out of the sea.

Thanks for the enlightening report.  I would like to add that while
reefs in the Keys may be fine, other reefs further north were severely
damaged.  I made my first 4 OW dives off Ft.  Lauderdale Saturday and
Sunday.  Having not seen these particular reefs (Barracuda and Hammer
Head) before Andrew, I can only say what the more experienced divers
saw:  they said a lot of coral was broken off the wall and a lot of sand
had been deposited on the coral.  It certainly wasn't as pretty as coral
I had seen on prior snorkeling trips.  Visibility was about 40 feet.

I've been told that visibility usually runs 60-120 feet at those sites --

how long before things return back to normal?

If you really liked an instructor's course, think about writing a letter
to the certifying agency documenting what you particularly liked.  You may
want to send a copy to the dive shop as well.  Not only will it do the
instructor's reputation some good, but your comments may be used to improve
the course for future students.  [end of my $0.02 worth]
