For the first time in history, Prodigy beats Internet to the punch on
a SCUBA topic.  They have discussed (to death :-) the fact that the Kodak

fine.

This is an interesting situation. The article in Diver Training had PADI being
very emphatic about EAN being outside the realm of "recreational diving".
What does this mean for Jeff's instructor? Is he now a renegade PADI instructor?
What will PADI do if they find out about this? Does PADI Keelhaul?  B-)

Consumer Tip:

For those in the San Jose (Calif) area, Reeds Sports Shop is having
their annual gun sale and reloading clinic July 23rd - 26th.

What's this have to do with scuba? Well...#4 shot will be at the
cheapest price I've found it. #4 (not the same as #4 buck shot) is
what's used in the nylon webbed weight belts. If you're making your
own weight bags, you can use #7, 8, or 9 bird shot.

Take the legs from an old pair of jeans. Cut the denim in 4" x 8"
strips. Sew up the two sides. Turn the bag so the seams are inside.
Put 3 to 5 lbs of shot in, fold in the top edge of the bag, and sew
up the top. I reverse the denim for different weights. Dark blue is
5 lbs, light blue is 3 lbs. Works great for pocket weight belts and
integrated BC/weight systems. (and you get a pair of fashionable
faded denim cut-offs to wear around the pool :-)

Note: an even less expensive source of lead is 'reclaimed shot' that
can be purchased from skeet/trap clubs. Unfortunately, it usually
comes in 100 lb bags (for about $30). Perhaps for dive clubs ?

Health Note:

Those in the shooting and reloading fraternity know about the
warnings and possible problems with handling lead. I'm surprised
that this is never mentioned in the sports diving communitee.

You should NOT eat, drink, smoke, etc, while handling lead.
Particles will be on your hands and can be ingested. ALWAYS wash
your hands thoroughly after handling bare lead. Vinyl coated lead
weights should not be a problem

To coat your own bare lead weights:

Run a strong string (nylon) through the belt holes of the weights.
Hang the weights between two trees, across your garage, etc. such
that there's 12 to 18 inches between each weight. Spray/brush liquid
tool handle (or equivalent) on all exposed surfaces. Do not coat in
the belt hole as it may make the hole too small. Allow to dry.

i've noticed that a few people have complained about certain films 
getting too "bluish" at larger distances.  this is a result of the 
fact that water "eats" light, not of the film type.  even the best
(and biggest) underwater strobes can't throw light more than about
5 feet (which is really a 10 foot trip - out to the subject and back
to the camera).  anything farther away will probably get pretty blue.

my personal recommendation for u/w film is fuji 50.  it doesn't go as
purple as ektachrome does, and reproduces the underwater colors 
beautifully.  one other thing to remember - as the bright colors 
fade with depth, you see things more blue.  the camera, with a strong
strobe will enable you to bring back images that may look different from
what you have seen while you were there (unless you have a strong 
dive light!).

	Well, I don't know about a religion, but I HAVE managed to make
sacrificial offerings to the Surf God each of the two years I've been diving. I
find that one offer per year seems to make him happy enough not to demand any
other offerings. :>

>Hi,
>I was wandering if anyone has some details on rebreathers...

The latest issue (should be July) of Rodale's Scuba Diving magazine,
the one being sent to DAN members for free, has an article on rebreathers
by Wes Skiles, featuring a description of Bill Stone's rebreathers
developed for cave diving. They may eventually be marketed by his company,
Cislunar. Projected cost will be about $5K for the simplest nitrox version,
$10K for mixed gas, and $20K for the full blown cave diving rig, with
the redundancy cave divers need - two complete mixed gas systems in one
pack.

I talked with Bill Stone about them at length last April when he was
testing them and training divers in their use in north Florida, and I
was safety diver for one dive. My impression was that they are further
from commercial production than Wes Skile's article might lead you to
think. Also don't expect to to just strap one on and start breathing
from it like a scuba. Operation is relatively complex. It was strange
to dive with someone who was not making any bubbles, especially since
it was my job to know if he was getting into trouble. Two possible
problems would be letting the O_2 partial pressure get too low,
resulting in loss of consciousness, or too high, resulting in
seizure. We were in shallow water so the latter wasn't a big worry,
and would be easily recognized. But if his back was turned it wouldn't
be obvious right away that he was not breathing. I'm not at liberty
to discuss technical details of what I learned.

The idea is simple. But believe me. The implementation is not. Even the
use is not as simple as you might think. The sophistacated computer control
does a lot for you. But you still have to make adjustments as you go up
and down. I was very impressed by the technology. This isn't rocket science
but it might as well be. Bill Stone has a Ph.D. in engineering and has
worked on space related things. One applications of the rebreather
technology is for space travel.

It is. But the tables you need have to be custom computed. Using a constant
partial pressure of O_2, and doing gas switches through the stages of
decompression complicates things quite a bit. Bill Stone's rebreathers
have computers to do it.

I am sorry for the probable repetitiveness of this post, but I
would like some advice on getting started diving again. I learned
to dive on the East Coast, and had loner equipment. Now I live in
San Francisco, and would like to know a few things:

     - Are there any good diving clubs locally.
     - What is the minimun amount of equipment I need to buy
       to get started, assuming I will dive with a local club
     - Where is the best place to buy equipment, new or used 
     - Where can I take a quick 'refresher' course, I am certified OWII

     Any info would be grately appreciated, Thanks, Marcus

I posted a couple of things about this a few months back when I first

While the increased resistance to breathing may cause *increased* air 
consumption, it may also *decrease* air consumption by reminding/forcing
divers to breath slower and deeper...

I'm not a deadhead either, but I do know the story behind Cherry Garcia
Ice Cream. Some deadheads sent a postcard to Ben and Jerry saying that
they had thought of a cool name for an ice cream. They didn't suggest a
recipe, though; Ben and Jerry created it based off of the name suggested.
This is detailed in Ben and Jerry's Ice Cream and Dessert Book (great ice
cream recipes and the story of how they got started).

I have no idea what ice cream you could name after Dan Quayl(e)...

not aattracted to this kind of blood - it is 'dead' so to speak so there is
