     It's a little trickier keeping track of two other people instead
of just one, but not enough to deny someone a dive if visibility is
good.  Sometimes if visibility is limited and the other two start to
drift apart I keep myself between them so I can keep track of both.  If
the visibility is really bad, though (10 feet or less) it's not a lot
of fun.  One night four of us went out together in less-than-wonderful
visibility; we finally split up and continued the dive as two pairs.

     For me, the whole point of having a computer is to be able to do
multi-level dives.  These profiles go way beyond the limits of tables
which assume the entire dive is done at the deepest depth.  We like
doing long dives, so we seldom went below 70 feet or so before we
got computers.  Now we can go down to 100 feet for a quick look at
something, then work our way back up into shallower water and still
have nearly an hour underwater.  It's like having all our old dive
locations plus a deep one thrown in for free.

     As for repetitive dives, the computer does that more simply and
reliably than you ever could with tables.  (Besides, you can't use
the tables any more anyway.)

     The worst thing about computers, as far as I'm concerned, is that
I'm becoming a snob.  I don't want to dive with people who are still
using tables because I've been spoiled by the profiles I can do and
don't want to give them up.  But, on the other hand, we went without
computers long enough that we know lots of local dives that are quite
enjoyable without going deeper than 60 feet - we can take our less
fortunate friends there.  :-)

I got one at Sam's for $199.  When I told a few of my dive buddies what I
paid for mine, it brought tears to their eyes.  Last time that I checked, 
they were still listing for $350.

The suggested retail price on a watch is usually double or triple that of 
the wholesale price anyway.  Often the manufacturer will tell the retailer
how much (if any) that they can discount a watch.  This is to protect
the small retailer from the big mail order/wholesale places.  The price 
stays up until the market is saturated.  Then it will get a deep discount.

Yes, many of the experienced people that I dive with use them.  I've had
mine to over 140ft.  In the dim depths it was easy to read the big,
luminous hands.  The buttons are operable at depth, but the winding 
(setting?) stem is not.

I do and love it.

It's no joke.  It is a durable, well designed dive watch.  I've been told
that very cold water effects the depth gauge.  This is not a problem
for me since I wear mine next to the skin and peel back the glove and
wet suit to read it, so it is always toasty...  Well, sort of.

The only thing that has caused me any problem is strangers saying
"Gee, that's a *BIG* watch!  You must be a scuba diver.".

A dive shop should NOT be the middle-man in your purchasing perscription
lenses. They should be doing nothing more than refering you to someone that
can help you in this non-diving area. You should have been dealing directly
with a retailing Optician or lens manufacturer, not a dive store.

Call any of your local lens crafters (looking in the yellow pages under
Optical Goods-Wholesale and Manufacturing, or Opticians-Dispensing). Let
them know what you need. More ofter than not those that deal only in 
wholesaling will give you a freebee 'sample' of a product that you need. :-)

My wife recieved excellent service and product from Curt Walker. He's an
optician in the San Diego area. Phone number: (619) 299-2878. He should be
able to tell you what to do/use.

Last year, 7 days before we were to leave for Cozumel my wife decided she
needed perscription lenses for her mask. I called Curt Walker and explained
our schedule. He had me read him the numbers off the perscription and mail
the mask and original perscription to him while he ground the lenses. I sent
cash with the mask. We received the mask (and change in cash :-) 2 days 
before we left on our trip. Price, including shipping, was less than if we
had the same thing done locally.

Hummm ... interesting (about price in Japan).  I suspect it was a case of
import duties imposed by Japan rather than a function of supply and demand.
At least in the Atlanta area, the steel Rolex Submariners are still being
sold at substantial discount from the List Price.

The discount price for the 18K gold Submariner appeared to have gone up
substantially as a function of demand.  In Grand Cayman (the discount
capital for expensive dive watches), the 18K model (which has the same
working parts as the steel model) sold for $9,999 in March 1991 when the
List (in the U.S.) was about $15,000 at that time.  I should have bought
another one (as investment) because when I returned to Grand Cayman in
Dec. 1991, the watch was being sold at the same shop for $16,500 --
essentially at U.S. List Price.  Now it lists for about $17,500.

But the 18K Rolex Submariner is a beautiful, functional, and well-crafted
watch that can be worn everyday whether you dive or not.  And if you
amortize its cost over 10,000 dives, it's less than $2 per dive.   8-)

I just got back from a Blackbeard's cruise, and can recommend it
highly.

Got to see nurse sharks and a black tip.  (Our group leader thinks
he got a photo of the black tip from about 2 feet.  As per our
previous discussion ... the man came up "speaking in tongues". ;-)
If the photo shop messes up the film, we'll have a ritual sacrifice.)

LOTS of turtles and rays around the "Donut Wreck".

Didn't get to see the resident green moray on Theo's Wreck, but
did manage what can best be described as "technical penetration".
(You could penetrate that wreck with a school bus, so even those
of us without Wreck Diving training could go into the empty hold
and take a peek.)

Nodules Wall is in good shape, as are most of the sites around
Freeport.  (Beware the Painkillers at Pussers ... for they will
make you silly.)  The sites around Bimini are quite a bit more
damaged, although all but one (Turtle Rocks, I think) should be
passable by next summer when all the silt settles.

If you want more details, or have specific questions, E-Mail.
I will definately be going back as soon as I have the vacation
time and money built up again.

        This tends to suggest to me that no matter what the problems of
computers are, they may be safer for the average recreational diver than the
use of tables.  I get the impression that most computer problems are clearly
identifiable as problems.  A wrong answer when working tables however is
probably missed until an accident forces it to be noticed.

A couple of weekends ago I was down on Long Island doing a bit of wreck diving.
After the first day of diving, the boat captain, also an avid wreck diver,
took us to a nearby shop to get air.  The shop's fill station was capable of
dispensing/mixing various different diving gases.  While waiting for my fill,
I met a couple of divers who were getting ready to dive the wreck of the USS
Monitor (a Gary Gentile's expedition, I believe).  When they manhandled their
tanks over to the fill station I couldn't believe the size.  They told me
they were 160 cf, but with overfills each tank could carry 200 cf!!  I didn't
get a chance to look at the stamped nomenclature on the tanks, so I don't
know if they were steel (probably) or aluminum, or who manufactured them. 
Someone else told me that a limited number of these monsters were imported

I've made ten dives with my ACE Pro-File (manufacturer gone belly-up, *sigh*)
without any major hassles. Once tank pressure measurement did not 'boot-up'
at the start of the dive, so I was forced to climb up, dry the computer and
restart it. Afterwards it worked OK. After that incident I've always started
computer at the surface, checked that it boots OK and after that started the
dive.

I do not understand this discussion that air-integrated computers are more
dangerous than normal ones. I hope that someone could point out how it can
be more safer to dive with a blank normal computer than with blank air 
integrated one. I throw in some seeds for a discussion:

If you have an air integrated computer:

	- every time you look your computer you see your NDL-status PLUS
	  your tank pressure. So you are aware how much air you have.
	- computer displays your NDL-time and your dive time left in this
	  depth with this air consumption.
	- if your computer dies, your air consumption should not get any
	  higher. You know how much air you had a minute ar two ago, the
	  amount of air is almost the same at this moment.
	- You should cancel your dive immediately and go up. If you were
	  diving inside NDL-limits, you should ascend to 3 m (5 m) for
	  3 mins (5 mins). If you run out of air there, you are shallow enough
	  to come up immediately
	- if everything fails and you run out of air: anyone heard of 
	  buddy-diving and buddy-breathing... :-)

I've heard this story, it is almost surely a rumour but here it goes: some
divers that has been used normal computers have been run out of air during
the dive, because they have forgotten to look their pressure gauges. All they
have been looking has been their computer and it's NDL-time. 
Don't know if this is true or not but it is at least possible.

Thank you for listening.

I've ordered a fair amount of stuff from Performance, based on their
low prices.  My take is that they're not top quality for much of their
inexpensive gear, but good enough.  Also, the lifetime guarantee works
fine for me.  Some stuff I've ordered:

- Mask (with diopters): love it, wouldn't give it up.  Saved $20 off
	of dive shop.
- Snorkel (el cheapo): behaves like al other el-cheapo snorkels.
- Fins (el cheapo): work just like fins work.  Cost $80 less than Avantis.
- Booties ($30): zipper on one became uncooperative after about a year; I
	sent it back (with its mate) and got a new set. 
- Skin ($40): blew out first seam after 75 dives, can be repaired, still
	a good deal.
- Dive bag ($100): works like a dive bag.  Same quality as all the other

I also use the Sherwood Genesis mask with corrective lenses and its one of the
best diving investments I've made.  I love it.  I decided not to go with actual
prescription lenses bonded to the mask due to cost verses relative
improvement .
Since water magnifies by 25% the prescription doesn't have to be exact plus,
astigmatism is not a real problem under water.  

BTW, before I bought the Sherwood I used to take an old pair of glasses with
the temples removed and place them inside my mask.  Hey, don't laugh it worked
(sort of)  :-).
