John,

I suppose if you want an excuse to not go diving, those would be
good regulators...:)  From experience I have had diving in the
northeast, you want a pretty durable regulator that can stand the
cold.

There was previous post about getting the Sherwood Blizard, but
I have seen problems with these reg's freezing up on not
terrifically cold days.

Most people in our area now dive pretty much on Poseidon's.
These reg's are pretty bulletprof and they have yet to freeze on
anyone in our group.  You will find passionate arguments on both
sides of the fence, so you have to at some point just decide.
I dive with Poseidon because of their reputation, their breathing
characteristics (cold, warm, deep, shallow...are all fantastic),
and personal experience.  I've been diving on some form of a
Poseidon sense '77 and had very few problems.

One nice thing about Poseidon is they do not require any extra
environmentalizing for cold water.  They offer a freezer cap
because of demand, but they are not necessary.  

IMHO

My impression was that the person asking was doing the sensible thing
by gathering information. I saw nothing irresponsible about it.
I recognize that it is impossible to judge either way on the basis of
so little evidence.

I generally disagree with a policy of refusing to answer questions
or discuss technical diving and just telling everyone to take
courses. Discussion is not a substitute for training. But a little
knowledge is not such a dangerous thing. In this case the person
appeared to be investigating the subject to decide whether or not
to pursue it further. I believe that open discussion is generally
a good thing. There really isn't anything mystical about technical
diving.

>Though my earlier post may have seemed like I am against NITROX and

Incredible. I never would have thought that from your earlier post.
Here is hoping for better communication on all sides.

I haven't dived at any of these places, but thought I would recommend that you
consider Bonaire if you want to do lots of good shore diving. Bonaire has the
best shore diving in the Caribbean for these reasons:

	Easy access - dives are very close to shore, usually less than 100'

	There are many good dives to do, so you won't get bored

	Dive shops cater to shore divers

	Out of the hurricane track - won't get blown out to sea

About the only negative factor is that Bonaire can be a pain to get to. KLM
Airlines is notorious for being late and losing your luggage.

It is much less than that, and standard procedure is to speed up the mixing
by turning the tank over several times after topping off and before analyzing.
Even if you did nothing the gas would mix by diffusion well enough that you
wouldn't be getting any breaths of pure O_2 in only a short time. The main
problem about getting the gases to mix quickly is to get an accurate analysis.
I know that mixing works because when filling by calculating the amount of
O_2 and air to mix to get the desired blend the analysis has always come
out almost exactly right. This would not be expected if the gas wasn't
mixed. It helps that the density of oxygen is close to that of air.

	Are you referring to the demand valve here ?  The first stage and
second stage should have DRY air flowing through them. The first stage of
an SE2 (was this a SUPREME, i.e. enviro-sealed ?) should not have frozen 
under these conditions. Note that due to the JOULE - COMPTON effect (flames
to me personally) will cause lowering of temperature in a first stage if
it is subjected to continous high flow rates. The SE2 is a diaphragm
device. Immersed in lubricant none of the moving parts are exposed to
the atmosphere (cold water). Has anybody else had this problem ?
	I use a Pro Diver from USD with an SE2 demand valve. This first
stage is often used with AGA Divator Mk II masks. (see Jaws - The Revenge)
and I have not heard of any problems. - Comments anybody ?

Ok, here are some suggestions.

	1)  Have your boat well lit up (the strobe could fail, be lost/eaten,
	    you might have to do a free ascent, etc).  Try to make some
	    unique light pattern on the boat.  (Yup, Ive done a long surface
	    swim to the wrong boat before. :-{)

	2)  Take two lights each.  Those darn things love to fail under water.
	    (If a light goes out, make sure you hit it.  It might come back
	     on, and at least your getting stress relief and a little 
	     vengence. :-))

	3)  Tie a cylume stick to the back of each diver.  This will allow
	    you to see them when they are not facing you.  (You can each
	    carry a spare stick if you like, for a complete flashlight
	    failure backup.  You won't see much by it, but it might make you 
	    more easily seen.)

	4)  Some people attach the light stick to their guages.  (I think a
	    lot of people think those things are really neat, and just love
	    to use them. :-))

	5)  Relax and have a great dive!

	 	           To All


Fellow divers,

I am currently doing research for the New York Sea Grant Association
and the Oswego Maritime Foundation to find out about a steam ship
that sank in Lake Ontario in 1919. The ship "David W. Mills" 
also known as the "Sparta" ran aground on Ford Shoals approximately
four miles west of the city of Oswego. Attempts were made to tow
her to deeper water all proved unsuccessful. She was stripped down
and later broke up. 

This summer the New York Sea Grant and the Oswego Maritime Foundation
undertook a survey of the wreck site. Upon completion of this survey
a document is to be produced detailing as much of the ship as possible.
This project has thus far attracted the attention of Duncan Matthewson
the famous marine archaeologist who excavated Mel Fisher's "Atocha".
as well as members of the community led by Dale Currier a local dive
instructor.

Here is the problem, we don't have much information on this vessel
other than it was a steamer approximately 200' long it was built
in Cleveland in 1874 and was owned by Frank Peterson. The salvage
company which undertook the wrecking was the Donnely Wrecking Co.
of Kingston, Ontario. It was formerly named the "Sparta".

We would like to find out who built it, if any pictures exist,
and any other pertinent information we can find. If you read this
and can contribute any information (i.e. books,pictures, etc.. )
please drop me a line at

         	jacs3500@penelope.oswego.edu 

We are looking to contact marine archaeologists, historians,
shipbuilders and divers involved in wreck diving. We would like
also to establish contacts in Cleveland who might be interested
in doing research on behalf of the New York Sea Grant Association.

Thank You.

How much extra warmth do these provide under a wetsuit?  I find that I get
pretty cold in my wetsuit below 60' up here in the frozen north, but I can't
afford a drysuit.  I would certainly consider spending $40 to keep a little
warmer.

We discuss a lot of advanced and technical diving techniques here in
rec.scuba, and the answer has never been "don't talk about it" before. 
The thing we have always advocated, though, is GET THE PROPER TRAINING. 
It's lack of information (and misinformed judgement sometimes based on a
lack of appreciation for the issues involved) that kills people.  The
newsgroup is a good forum for discussing some of the issues involved in
any aspect of the sport, and it can be extremely important for that,
because it brings divers together from right around the world, so you can
find out what's happening outside your local area, but it can never
replace some personal training and practical experience with a trained,
qualified instructor.

>Personally, I'm interested in doing some Nitrox diving and getting properly
>trained (trained, then dive) and I'd like to avoid having Big Brother stop it.

I'll second that.

In response to your post, I would like to add that I would have to
agree with a couple of the others and reccomend the Poseidon as a
GREAT reg. as well as the Blizzard as long as $$$$$$ is not a BIG problem.
They are EXCELLENT regs., certainly bulletproof and have a GREAT
reputation as a solid, dependable reg. If they are out of your $$
range, I would go with the BLIZZARD and *not* the OASIS due to it's
moisture retention properties.

Hope this helps,

        Re:  BC and drysuit together

        Another argument for using a BC with a drysuit is that the drysuit is
not particularly suitable for generating enough buoyancy to get your head
well out of the water at the surface (as might be needed in rough weather).
If I try to float high at the surface using dry suit air only, the air in the
suit gathers around my shoulders and farts rudely out through the neck seal.
        I have heard of an incident where a diver, against the advice of
companions, jumped from a boat into the water wearing a dry suit without a
BC.  To prevent sinking, she inflated the suit well before jumping.  A few
seconds after she hit the water, she was unconscious - the air in the suit
rushed to the top once she was in the water and the neck seal pressed on her
carotid artery.  Fortunately, the problem was seen by other divers and she
was rescued.
