I haven't used the Dacor or Sherwood products, but I have used the Poseidon
Cyklon 5000 ("Hockey Puck") in below freezing water with no problems. I saw
a TV special about a guy doing research in the Antarctic who was doing two
dives a day in -5 degree F water, and he was using a Poseidon Cyklon. He
did say that you can't use the reg until you get in the water because the
moisture from your breath will condense and freeze up the workings. Apparently,
once you're in the water, the salt keeps this from happening.

The Cyklon is also a good general purpose reg; I've used it all over the world
and never had any problems at all. I like having the bubbles go out the side
instead of in front of your face, too. It also works the best in the upside
down position, the best position for sneaking up on critters under a ledge.
Many (most?) regs tend to flood and breathe hard in this position.

Does anyone have recommendations of dive operations/resorts, or

        {stuff deleted about O2 and N2 separating in your tank...)

        O2 and N2 do not separate in your tank due to a physical
effect called entropy; it is one of the law of thermodynamics- the one
that says that you can never break even.  Once gases are mixed, it
requires energy (and a lot of it) to cause them to separate again, so
no need to worry about spending the first fifth of your dive on pure
O2...

        While I find it hard to believe that pockets of different
gases remain in a tank after a fill, I could imagine that there might
be some residual in the valve assembly, causing the slight differences
in mix results immeadiately after filling.  Or perhaps the sensor is
still equilibrating?

        Good luck with your NITROX!

Cayman Brac has great boat diving, lousy beach diving.  To get to any
kind of shore diving, you have to get over to the north side of the island -
and both of the resorts are on the south side.  If you have a van (I'm not
sure how you got it there?) you can dive the north side from shore.  How 
really good the northside shore diving is I can't say - I did one shore-based
night dive there and it was good but not spectacular.

Actually, except for insisting on two analyzers (which is a good idea), this
is exactly the procedure in the shops I use in Florida, i.e. analysis when
the gas is mixed and a second time, with the customer witnessing and
signing, when the tanks are picked up. Customers must be nitrox certified and
their numbers are recorded in the log each time, too. The only difference is
that the same analyzer may be used for both tests. It would clearly be better
for the customer to use his own analyzer for the second test. This would help
detect if there is a problem with either the customer's or the shop's analyzer.
We may not have as conversative a diving medical fraternity, but we've sure
got a zealous community of lawyers. Occassionally that isn't such a bad
thing.

As a poor graduate student I can live with using the shop's analyzer,
especially since I know the people doing the mixing and the calculations
provide some check on the analyzer (and vice versa). So I'm really not
betting my life on the analyzer alone.

I dove for years and years and years without a BC (not because I wanted
to but because they didn't exist--although if they had existed I still
might not have wanted to).  So, diving without a BC, wearing a farmer
john 1/4" neoprene wet suit and using both steel and aluminum tanks,
singles and doubles; and weighted so that I was neutrally buoyant at the
surface (my eyes at the water line with lungs full of air), at depths
ranging from 10' to 220' [NOT RECOMMENDED!!!], I haven't had any
problems either with "squeeze" (see below) or with ascending.

Vis a vis squeeze, I don't see how a BC affects this.  Do you mean the
loss of buoyancy caused by the collapse of the gas cells in a
closed-cell neoprene wet suit?  A BC has nothing to do with squeeze in a
try suit, either.  Perhaps I misunderstood you.

By the way, I now use a BC when diving with SCUBA, although with a dry
suit I think it's a bit of expensive overkill and just one more perhaps
faddish piece of gear, foisted on us by the never ending greed of the
equipment manufacturers and sellers, that I have to f*** with getting it
on, wearing it, taking it off, washing it, and storing it.

My personal opinion, of course, not shared by the various organizations
which have certified me (and may wish they didn't upon reading this).

Hi I'm a 20 yrs old guy from Finland and I'm going to try scuba
diving. Now I cuold use some advice.

1) How much you have to pay for equipement in Europe? 
   (I'm going to go there next summer, and it might just 
    pay some of my money to bring some stuff with me)
    I'm interested in suits and/or bottles & regulators

2) In here they have two systems: CMAS & PADI. 
   Is there a difference? If yes, what?
   And which do you prefer? Why?

3) The cource costs here around 300-350 dollars
   would it be better to take it in Europe?

Thank you in advance.

I dove last week in Baja California (Cabo San Lucas) in a 2/3 mil full
wetsuit.  Water temperature about 81 degrees, visibility 60-80 feet.  Air
temperature was 85 degrees.  Minimal surf.

I am diving this weekend in Monterey, California, where the water will
probably be about 53 degrees, with visibility hopefully as much as 20 feet.
Air temperature will be upper 60's.  Quarter-inch wetsuit.

I am very pleased with the original version of the Citizen Aqualand (digital
window for dive functions).  I use it as a backup to my dive computer.
I use the bezel to time the first hour of my surface intervals too.  I've had
mine for two years now.

On a recent week of diving in Kona, Hawaii, the depth and time (current & max)
on my watch usually matched my Suunto Solution computer exactly.  The two never
disagreed by more than 1 fsw or 1 minute.  I haven't tried it's max depth or
max dive time alarms.

While I really like the looks of the watch, the digital window is sometimes
hard to read and is not illuminated or radianti (night dives...).  It's
sometimes hard to button the sleeves of a long-sleeved shirt around the watch
due to its bulk.

BTW, I found the article in Rodale's _SCUBA_DIVING_ to be pretty weak.

While I haven't seen the new Aqualand II, all of the watch hands used to
replace the digital window look pretty confusing (Rodale's comment too).

I'd certainly recommend the original Aqualand -- especially at "close-out
prices.  The cute little SCUBA tank that is used to package it is worth the
price of the watch alone :-).

>  5. Brac Reef             Cayman Brac

	I can say that Brac Reef offers two morning boat dives and an
afternoon "load up the truck" shore dive.  The Little Cayman boat dive
trip is a two-dive trip as well, with no afternoon dive that day - there
is a night dive scheduled on the day of the Little Cayman trip.
	Boats are necessary to get to the walls, which is the main diving
you will do at the Brac and Little Cayman.
	Brac Reef has a very good operation, with (now) four boats and very
conscientious and friendly staff of dive-masters and crew.  The hotel is
small and friendly, with excellent food.  I recommend the "all inclusive"
package, which gives you an "open bar" for beer and de-briefings.

	The Tiara on the Brac offers similar accomodations, but I much prefer
the smaller and friendlier Brac  Reef Resort.

Just to round out the information....
(Bias:  I too love poseidon's)

Poseidons (Odin and Thor) will shoot ice crystals into your mouth and the
back of your throat on cold water dives.  (They hurt.)

Poseidons WILL freeze.  (I now have the inexpensive and easy to self install
environmental 'caps' installed.) 

Poseidons move a LOT of air.  When they free flow, if you can't shut them down,
you'll be out of air soon.

There is a mechanism built into the connection between hose and 2nd stage that
allows pressure relief.  This too can shoot ice crystal (on the surface).
They too, hurt (and can be quite suprising).
