Subject: Citizen dive watch.  need info.
Organization: Columbia University Department of Computer Science
Date: Tue, 29 Sep 1992 17:05:02 GMT

hello net.divers:

I have read the FAQs about diving watches and the like.  I have read the
discussions on this net about various diving watches as well (including
the receint posts).  However there has not been much discussion about the
Citizen dive watch (I saw only one reply about it in the archives).

Last night I was walking around the "electronic district" here in New York
City and I figured that I would price some watches.  Well the Citizen dive
watch is going for about $189US, which is a good price considering that it
used to go for upwards of $350US.

It seems as though Citizen has just come out with a new style dive watch
and this has caused the older one to drop in price dramatically.

Is this a serious dive watch -- ie will it give me the info that I would
need on an average dive?  Does anyone use it?  This seems to be a good
price for a good watch, but if it is a joke for scuba I would rather pass
it up!

I understand what you're trying to do.  My certification
only goes as far as PADI AOW.  I've learned my advance diving
skills from the people I dive with.  Some of them are instructors,
some are avid divers who have done extensive reading and talking
to experts.  The expectation is that if you want to learn from
this group, then you listen and follow their guidelines.  It
worked for me.  We all know people with wallets full of c-cards
who aren't worth a damn in the water.  At the same time, the
practical (in the water work) is invaluable.  I would suggest that
you evaluate the people you dive with.  Is there anyone who can help
you with learning advanced skills?  Does this person or group have
a good knowledge base?  If the people you dive with are on the same
knowledge level as you are, better spend the money.

Well, the largest size cylinders I've seen for sale here in the UK are
18 litre beasties.  If these are 232bar WP then this would give 4176
litres or around 148 cf.  Of course, they could be 300 bar in which case
the numbers would be 5400 litres or 190 cf.

The problem with cylinders this size is they they tend to push ones
center of gravity further backwards than is comfortable (this is
extrapolated from using a friends 15 litre and assuming that an 18 litre
would be even worse).  Me?  I'll stick to my rinky dinky little 7 litre,
300 bar twins which provide 4200 litres or 148 cf (much easier to squirm
through those holes in wrecks!  :-)

     My wife and I have Oceanic consoles.  I don't know the model name
(I never heard a name given to them) but they sound like what you're

the compass on the other; my wife's has the computer and compass on

hers, we're just one happy family... :-)  I like having the compass on
the back because I don't use it as much as the other dials, but it's

Amen!  This goes for octopi as well.  I see way too much reef damage

I went to Cozumel this year with a group of 18.  We took Pepto-Bismol

bottled water as well as beer and sodas.  All ice is made from the bottled 
water.  This limits the amount of problems normally found in Mexico.  Only

are now selling suits with these features. Is your head movement
restricted with the attached hood, does the flap around the neck front
seal well or get in the way etc ?  Is the john that pulls over the head

diving is expected to be in the 40 - 70 deg. F range.

I apologize if this post isn't totally relevant to scuba diving.
It's more about snorkeling, which I assume you all will know about.

I'm trying to organize a trip to Cozumel for some friends and family
(ages 22-59) around xmas.  I've already looked at the archive file
on Cozumel, which has a ton of info, but I still have some questions.

Before I get to the questions, let me describe the group.  My parents
took a scuba class this spring, but are still rank amateurs, and they
are the most experienced among us.  Most of the rest of us have
enjoyed snorkeling (definitely the highlight of our hawaii trip 3
years ago), except for one or two who have just learned to swim
recently.  

The most important question is, Is Cozumel the right place for us?
We are looking for a place that:

1) has good snorkeling (accessible from shore)
2) has the possibility of diving (and lessons)
3) is close enough for a side trip to one or more of the Mayan ruins
4) is not as crowded/developed as Cancun
5) is not ridiculously expensive
6) has food that won't make us sick
7) has natural beauty and other attractions

Does Cozumel have enough snorkeling to keep us happy for a week?
People have recommended La Ceiba and Chancanab(sp?) for snorkeling,
but another comment was "For non-divers, Cozumel is boring after three
days."  I thought lots of non-divers went there?

Can you suggest a better place for us?  Some posts mentioned good
snorkeling at Isla Mujeres.  Would that be a place to stay?

Or how about somewhere on the mainland, say near Xelha, Akumal, or
Tulum?  Are there hotels/resorts there?

Any comments would be helpful.

Thanks.

The other obvious diving career is marine biologist ... I'm working on my PhD
in marine biology, and this involves diving on a regular basis.  The essence of
the career is biology however - ie, you can't get a diving qualification and
become a marine biologist without doing some biology training as well.  Hope
this helps.

	NORFOLK, Va. (UPI) -- A federal judge has ruled a Texas oil man has no
right to dive for artifacts from the wreck of the Titanic, and ordered
him to call back his high-tech salvage crew that was poised above the
wreck in the North Atlantic.
	U.S. District Court Judge J. Calvitt Clarke Jr. said Jack Grimm's
Marex-Titanic salvage group has no rights to the contents of the ill-
fated ocean liner, which hit an iceberg and sank on its maiden voyage in
1912, killing more than 1,500.
	The salvage rights still belong to Titanic Ventures of Southport,
Conn., Clarke ruled Friday. The group last conducted a dive at the site
in 1987 and plans another expedition in 1993.
	Grimm's group, based in Memphis, Tenn., contended that Titanic
Ventures had abandoned the wreck by failing to return for five years,
but Clarke agreed with the rival salvage group, which argued that the
sheer difficulty of the project made the delay unavoidable.
	Grimm's crew had circled the wreckage site -- the Titanic lies 2 1/2
miles beneath the sea south of Newfoundland -- during stormy conditions
this week, waiting for Clarke's ruling.
	After the judge's order, Grimm, 67, went to his rivals' attorneys
with a proposal to make exploration of the wreck a joint venture. His
offer was rejected.
	``We're not interested,'' Arnold Geller, president of a New York firm
that raises money for Titanic Ventures, told reporters.
	Grimm said he expected to lose $1 million on the aborted expedition.
But he compared it to the risks involved in drilling for oil.
	``Once, I drilled a 22,000-foot hole in the desert in New Mexico,''
recalled the wildcatter and explorer from Abilene, Texas. ``It took me
six months, and it was dry. This (expedition) is just another dry hole.
When these things happen, you just go on your way and put together
another deal.''
	The wreck of the Titanic was located in 1985 by a U.S.-French team
led by Robert Ballard, a scientist at the Woods Hole Oceanographic
Insititution in Massachusetts. Two years later, Titanic Ventures -- with
the help of the French government -- explored it with a television-
equipped robotic diving device and recovered more than 1,800 artifacts.
	The group plans to collect enough artifacts to fill a museum in New
York honoring the ship and its victims.
	The expedition planned in 1993 will be conducted with the aid of two
manned Russian submarines.

As someone with vision too bad to get a private pilot's license and good enough
to carry an M16, I've taken a lot of interest in vision correction,
particularly in diving.

The glue used is a special optical cement.  It is set under a vaccum and with
exposure to a particular band of UV.  Not your amateur type stuff.  If the lens
popped off after six months, the optician that mounted them owes you a fix, as
mine have lasted 6 years (of careful use).  The cement has the same, or nearly
the same, index of refraction as optical glass, so this avoids unintended
refraction.

My current mask is a TUSA Liberator, with custom ground lenses.  A vast
improvement in many respects.  There are a limited number of opticians that
will do this, and it is pricey (I have a $200 mask).

Lenses that are bonded to the mask plate are typically cut differently than
regualr glasses.  As a result, you get a slightly different correction, and the
lenses need to be bigger (this is also due to the fact that they are further
from your eyes).  One big difference is that the front surface is flat or only
slightly convex, whereas your glasses are very convex.  This is needed to make
the cement work.

Again, this is all from amateur research.  I can send more info IFF you _mail_
me a request.  I won't/can't post the optician I use, as that would really
constitute commercialism.

Oh, definitely go for it.  The battery life is up, the reliability is
way up, and the price is down.  In addition, they've finally admitted
that all Delphis always worked to 300fsw, and so every Phoenix is
rated accurate to 300fsw.  I doubt that is what your top priority was,
but it is progress.  

The dive logging helps decompression research, too.

Who's got experience with Diver Propulsion Vehicles (DPV's) aka scooters?
I'm going to purchase one this winter.  I'm particularly interested in:

(1) a DPV rated to 250 to 300 fsw - or one that comes with, or can be
    upgraded to work at those depths.
(2) It's got to be from a reputable company who will still honor service.
    (I've heard interesting things about the Tekna DPV, but where can
     you find parts when it breaks?)
(3) Although I'd like to get a Zepp it's just too big to handle getting 
    in and out of the water - not to mention seriously expensive.
(4) Buoyancy considerations when using a DPV - how do you handle it when
    you're hanging?  Where/how do you "park" it if you want to stop, and
    say visit the inside of a wreck?
(5) How much colder to you get when using a DPV?
(6) Did you have to alter any gear placement to avoid having it get caught
    in the props or torn from your body?  (Keep in mind I'm a wreck diver)
(7) How do you store the thing during the boat ride out and back?  (I'm
    thinking about a large plastic garbage can filled with fresh water)

So here's your chance - unload all your good/bad scooter "tips" and
experiences, as I'm keen to hear them all before I got shopping.  I've
already been to a few area dive shops and gotten the marketing
rhetoric, but now I want some "straight talk".
