Greetings, netters...  I'm a relatively new certified diver through IDEA and
will be doing a bit of travelling to ideal dive locations the next few months.
First, I'd like some information on diving in the LaJolla area.  I'll be there
the end of October for 5 days and would like to get a day or two in the water.
Anybody know of good shops/locations around there?  
Second, I'll be in Maui in December with parents (who aren't certified) and
I need info on shops/locations and maybe even a buddy or two who might be
in the area the same time.  Please respond to my email address listed below.
Thanks in advance...

Wow, that's a really mixed bag.  The Rolex Submariner is superb:
300 meters, and they really mean it, accurate, bullet-proof,
and costs $2600 if you can find one, which you probably can't, as
they fetch nearly twice that in Japan, where they are all being sent.
Tag-Heuers are, as far as I can see, identical to Innovative Time watches
which can be had at K-Mart for $50, making me wonder about the
$300 Heuer price tag.  Seikos are good watches, but you have to be real
careful with the depth ratings.  If is says 100m, that doesn't necessarily
mean that you can take it down that deep.  Stresses on a watch under water
are a combination of static pressure due to depth, and dynamic pressure
due to movement.  It is the combined stress that cannot exceed the pressure
rating.  Also, some watches (I'm not sure about Seiko) limit button
pushing underwater, rendering most of the watch functions inoperative.
Pop for a Rolex if you can find one; otherwise, I think the 
Seamaster would be your best bet; it's a very fine watch.  Good luck.

No, I'd watch the ceiling creep away from me, and stay 10' below it,
at a nice, clearly marked increment on my (analog) depth gauge.  

E.g., when the ceiling hit 15' I might move to 25', and at 5' I would
move to 15'.  I wouldn't come above 15' unless things were really calm
and I'd already finished my decompression by a margin.

Subject: re: bonding lenses to your mask
Date: 29 Sep 92 13:07:34 GMT

In response to the people who were inquiring about glue for bonding their
prescription lenses to their mask.  If your dive shop can't get it done,
first try going to an optician who can probably do it on the spot or at
most a few days.  Or if you really want to do it yourself, you can order
the bonding material from places like "Edmund Scientific".  The bonding
material is usually a clear liquid that is cured with UV light, so if you
do it yourself, make sure you have an appropriate UV source to cure the
material correctly.
   For the person who wanted to take the lenses out of their glasses and 
glue them to their mask, I wouldn't really recommend that because one side
fo the lenses should be flat so it fits correctly against the flat mask.
Normal lenses from glasses are usually curved on both sides and you
won't get a good fit and there will be an air space between the mask glass
and the lenses.

available.  Any info would be appreciated.
BTW, new to this group, but impressed by what I see.  I can

I would appreciate a recommendation for a resonable priced lodging on Grand
Cayman preferably near Seven Mile Beach/Georgetown.  My wife and I had a
great plan laid out with another couple, but because of illness they had
to drop out and we had to cancel our condo because it was too expensive
just for us!  Is it possible to find accomodations in the area for less
than $150/day?  If not, would it be worth moving to the east end and
arranging to travel back and forth the Georgetown?  I am a diver - my wife
is not, but she likes to go out on the boat and "bubble watch."  The problem
is I am kind of stuck with airline tickets, but have no place to stay.  We are
scheduled to be there the first week of November.  Any and all suggestions
will be gratefully received.  Please send any suggestions directly to me
at my BITNET address or if there is no other choice, post.  Thanks for
your help.

As part of the ongoing process of building an archive on scuba gear I am
currently accepting "personal opinions" on scuba equipment.  I am only
going to accept information on the five big purchases: First stages,
Second stages (regulators), Computers/consoles, Bouyancy compensators,
and Suits/skins.  The summaries will be e-mailed to submitters and
posted to this news group.  This project will only be as effective as
you make it.  An FTP archive will be maintained.

All responses should have the following information:

Type of equipment
Model
Manufacturer
Price paid
Place purchased
Length of time it was used
Physical condition of item when used
Conditions under which it was used

Most importantly:  
Your name 
E-mail or Postal mail address 
Phone number
Number of dives
Special dive certifications

Finally: your opinion/observations of the equipment

I have phoned as many manufacturers as I can think of and hope to get
their assistance in divying out test equipment in the future.  If you
look like my idea of an objective submitter I will try to scare some
equipment your way.  Additionally, I am including in this evaluation
the opinions of some dive-master/long-time friends.  My opinions will
not be used except as confirmation of equipment defects.  I promise
to contact you by the most expediant manner on topics for which you
have submitted opinions.  This will be an iterative process.  Direct
all flames to me - by e-mail.

I have a prescription mask and one of my lense popped off.  I called 
my dive shop to find out what type of glue is used or how quickly they 
could have it back to me since I plan on diving in a few days. Their 
response was they have no idea what type of glue is used and it would
take at least a week to get it back if they send it out. Does anyone
know what type of glue I can use that will not distort my vision?
I sure would hate to ruin the mask trying to fix it myself since it's
only 6 months old.

Greetings

I'd like the opinions of you advance-divers/divemasters/instructors
out there, on this:

For someone who has the following attributes/qualifications:
- OW1 (Naui)
- extremely comfortable and fairly 'agile' underwater
- in good health
- very good swimmer

is it okay for him/her to acquire skills taught in Advance courses
by just buying one of them text books and studying it and practise
whenever s/he can?   Ok, ok, I admit, it's me I'm talking about.
The reason I ask this is that I'm not willing to part with the
course fees (S$400-500) for something I can learn on my own when I
go for my trips (with a buddy of course).  Of course, I won't get
the certification but I will most probably have the knowledge and
skills an Advance diver supposedly has(?).  

I've seen one of those PADI Advance Divers textbooks and it looks
rather comprehensive.  I know I'll probably get flamed, but I just
want to know what you people think.  Thanks for any input.

Sincerely
Heng Kek

My Datamax, when it died, did keep accurate (or at least
plausible) track of current depth.  It just misremembered 30 feet as
195 feet when I returned to the top.  Coming straight to the surface
from 100 feet without a decompression stop seems stupid.  I believe
that even the Datamax instruction manual suggests decompression stops
for dives made within the limits.  It definitely reduces the chances
of bends.

I'm curious about dive computer failure modes.  Do many fail in a mode
that is dangerous?  With failure, if I had stopped diving for the day
I would have been safe.  I actually switched to tables, which was also
safe.  I was unhappy (even a bit distressed) about the failure, but I
wasn't under any additional risk of bends.

Are there many cases of computers incorrectly keep track of nitrogen
levels?  This may be difficult to determine unless there are 2
computers attached to a single diver.  What are the common failure
modes of a dive computer?  Losing the maximum isn't very serious,
especially on the surface.  At depth someone could panic and ascend
quickly, skipping a safety stop, but divers should take responsibility
for safe ascents even if there is equipment failure.  The problem with
the instructors dive is much more serious.  Perhaps this question
belongs in comp.risks.

A mail inquiry may have bounced, so I'll risk embarrassment and ask
where all the net.world can hear - If this is not a joke I'd be
interested to hear the details of how you do this. It would be great
to amaze my friends, even if the technique can't be used in caves.
Unless you have some modification to the switch you must be somehow
locking it in the on position (maybe using a rubber band on the
trigger?) This might not be safe in a confined environment, even
wearing a helmet. The technique would probably be fun when just
playing around in open water. What would you do about a runaway
scooter if you lost control while learning the technique?

But now that I've thought about this a little I suspect that you are
joking. This would not be the first time I was taken in by a joke in
rec.scuba. It is amusing to contemplate, though.

 Another point (this applies to the USA, and may not apply elsewhere) is
that items purchased outside of the USA may not be covered under any type of
warranty!!!  Such items are sometimes referred to as "grey market".  Be
aware that even some deals found inside the USA can be considered from the
"grey market" if the unit is not purchased through an authorized dealer.

  Be careful with this... a good deal may turn out to be very expensive if
you need any warranty repair work.  This goes for many items, not just cameras.

 Good luck.

I do not know if there is a computer that takes this into account but since
most computers are based on the tables then you would just had 10 feet to you
actual depth.. Some computers show you gassing out (like the Sherwood source
which I have) I just allow some extra time after I have totally gassed out 
according to the computer.. I can not see myself doing an extremly cold dive
for a very long time and one that would be below 60-80 ft so I do not think 
that I would even come close to getting to ND limit.

Have one person watch the next person, and so on in a circle.  Do NOT

No, you can't get an RNT from the computer.  I dive with two computers
which use the same model so I have backup in case one fails.  

If you really want to get back to a table you have to be really
careful and pretty knowledgeable.  That said, I know only two or three
divers who are capable of explaining how to do this.  I count myself
as one of those, and I know a lot of divers.

I doubt it.  I know of no boat insurance policy that discriminates
based on level of certification.  Sounds like a convenient and
hard-to-dispute lie.

If said boat operator wanted to verify your abilities through in-water
observation, say via an escorted deep dive, that would be better and
more accurate, to my mind.  That is, as long as any attendant costs
were made apparent up front.
