For sale: Womens medium/large wetsuit (*$75*)

Medium/Large womens Parkway wetsuit...

I'll make a rough guess and say it's for someone who's about 5'8" and
weighs around 140lbs. However, since this is a shark skin suit, there
should be room for error. (Shark skin meaning no nylon lining on the
outside surface allowing more stretching and freedom of movement.)

I will try to describe it.  It is a nylon lined jacket and pants
suit.  The jacket is long sleeved with one zipper up the front and a
"bever tail" strap.  I think the pants have two zippers at the ankles
to make getting them on easier, but I'll have to check. The suit is
about 1/4" thick for colder water diving. The Jacket is in excellent
shape, the pants are in fair to good shape.  Again, all material is
nylon lined inside and shark skin out side (textured neoprene).  Make
an offer, thanks...

In California we have about 800 miles of coastline. Living in San Diego
I can report last weekend we had visibility of 20-30 feet of the shores
of La Jolla. Ambient air temp is about 65-70 at 8:00am, so getting 
geared up is no problem. Luckily, we dove at high tide which at that
time was 0-1' surf.

Hope this helps,

Randy

Just to clarify what I think you're saying, some regulators do have exposed
moving parts.  These are subject to freezing, as ice forms on the outside
of the reg due to the cooling effect of compressed air expanding inside the
regulator.  I've had a quarter inch of ice caked on one before.  This ice
can jam up exposed springs, pistons, and diaphragms, if they are exposed to
water on one side, causing freeflows.

The solution used by most manufacturers with their "environmental kits" is
to place a rubber boot over that end of the regulator and fill it with some
type of oil.  Ice won't form over the boot, so ambient pressure is still
available to the parts inside.  (When this was first done as a
field-expedient fix by Canadian Navy divers in the "bad old days", they
allegedly used "Crisco"-brand cooking oil inside a condom.)

Sherwood has a different solution (which I believe is covered by their
patent).  The ambient-pressure chamber has a pinhole air leak into it, and
has a very small external port, so that this chamber stays dry the whole
time.  This causes a slow stream of tiny bubbles from first stages so
equipped, but the net air loss over the course of a dive probably wouldn't
fill your lungs once anyway.

Might I take a moment to say a few words about that word, "homebrew"?

Things that affect the quality of a nitrox mix include having the right
equipment, properly maintained, being operated by a trained, qualified
individual.

Things that do NOT affect the quality of a nitrox mix include whether that
equipment is being used commercially or in somebody's basement, or whether
that person is mixing it for sale to others or for his/her own use.

Thank you.

From: Ron Danner <RPD@psuvm.psu.edu>
Date: Thu, 12 Nov 1992 15:09:41 EST
Organization: Penn State University

     I have just returned from a 5 day trip to the Sunset House in
Grand Cayman.  We were very fortunate to have had great weather -
no rain - and very calm seas the whole time.  My overall impres-
sions can be stated in three ways (1) EXPENSIVE, (2) diving with
the rays is great! and (3) the rest of the diving is pretty good.
     I have visited a number of Caribbean Islands - Guanaja, St.
Kitt, Saba, St. Maarten, Nassau, and Cozumel.  Grand Cayman is by
far the most expensive.  I found it so expensive that it detracted
from my enjoyment.  Everything is expensive - lodging, diving,
taxis, food, you name it.
     Fortunately we did not go on a dive package to Sunset House.
The dive package includes a two-tank dive in the morning and all
the shore diving you might want.  We went on one two-tank dive
with them and visited two rather dead reefs just off shore from
the dive shop.  There were some interesting fish to be seen and
some crevices to swim through and between, but there was little in
the way of interesting coral or sponges.  The reefs on the west
side tend to be damaged by the storms as well as the divers.
     The interesting dives were a trip to Stingray City ($45.00
US) and a day on the Manta - 3 tank dive trip ($125.00 US).  NOTE,
these are NOT included in a dive package.  If you went there on a
dive package you would have to pay additionally for them.  The
reefs we visited on the Manta were great - almost pristine.  The
Stingray experience was unique - a real blast.  But if I had
already paid for the dive package and not realized that the really
good dives were not included I would have been rather upset.  I
emphasize this because Skindiver has raved about the Manta at
Sunset House in a recent issue, but they did not say it is not
included in the usual dive package.
     Overall I wound not return to Grand Cayman.  The diving was
good, but I saw more or as much interesting underwater life in
Honduras (Guanaja), Saba, and Cozumel.  Unless you have a lot of
money to throw around I recommend staying away from Grand Cayman.

I have talked to my teacher in Underwater Technolgy about nitrox.
He has looked into the subject of nitrox in recreational diving and asked
the local gas company AGA about gas-mixing. Their method for mixing gases in
smaller batches is to mix by weight. I.e. xxxx grammes of oxygene and yyyy
garmmes of nitrogen into the tank and then put the tank for some time (>1 h)
on a tank rolling bech to mix the diffrent gases. Aftewards the mix is analysed. 
Then you only have to pay the expesive bill (210 SEK ~ 35$) and use your mix.
This price might include transport of the bottle to the lab.
I think that they roll the bottles as a standard procedure regardless of the
gases you have orderd. For heliox (H2-O2) the density difference is about
1 to 10 if my memory is right. 

My teachers conclusion is that nitrox at this price is hard to justify for
recreational diving since he thinks that divers tend to run out of air (gas mix?)
too soon to have any advantage of nitrox if the make one or two dives a day.
The price is to expensive to use nitrox only to increase safety.
He allso showed me a new Norwegian table in both air and nitrox versions.
The nitrox version had diffrent oxygene toxicity limits for divers with
full face masks and divers with helmets. They argue that a helmet diver
is monitored from surface by telephone and that he has a lifeline to his tender
so he can be pulled up if he gets cramp.
Nitrox diving with "bite-only" demand-valves is not allowed because the
diver will lose his D.V. if he has an attack.

In Sweden nitrox have been in use by the Navy for more than a decade in 
semiclosed rebreathers (AGA-ACSC with full face mask), and there has 
allso been some efforts to promote nitrox for use by professional diver
but the use is limited so far.

I have the US Divers SEA2, the first stage is  environmentaly  sealed,
but I have freeze up problems with the 2nd stage.

If I am below  about 90 ft in water 5C or  lower,  I often  get a free
flow on the second stage.

I would  definitely go for the US Divers cold water 2nd stage, the one
with the little heat sinks on both sides.

Other than that, I am totally satisfied with it in all other respects.

Reference these 'horse collar life vests'

In the U.K. many a diver will be seen using one, I instruct in the University
of Bristol Underwater club and all our 'BCs' are English buddy Pacifics with 
'power inflator' - Costing  85 pounds new (i know what not in dollars) . 
Un fortunately most people can only buy them with the 'emergency cylinder'
included in th e price of 150 pounds. Second hand they go (with cylinder for 
about 50 pounds). This compares to BC prices in the Uk of 200 pounds up to 340 
for good ones (I beleive diving equipment is more expensive this side of the 
water)

I use an 'ABLJ' (adjustable buoyancy life jacket) with my drysuit, and used to
 with my wet suit. It gives pefect headup position on the surface - but is
uncomfortable to wear at 30m+ (the crutch strap can pull quite hard between 
the legs)

Most Drysuited divers use them as purely safety devices and not for routine 
buyancy control

(I don't use mine of shallow shore dives, the only disadvantage is you lose 
the torch pocket !!)

There are loads of surplus ABLJ's in Britain from gear freaks updating to 
STABs (do you call them STABS/ADV ?) when for a drysuit it is just 300 quid 
spent on buying another bulky piece of equipment (yes i have dived with them)
 

my 2 pence worth (.001 of a cent...)


p.s. Bristol has just got nitrox, 6 pound a fill compared to 2 pounds for air
