[My apologies if this appears twice -- I posted this two days ago and it
hasn't shown up at my own site yet.]

My husband and I are planning a dive trip to Hawaii (Kona) the week of
March 15.  Can anyone give us an idea of what we can expect for weather
and water conditions at that time of year?

Thanks in advance!

I've been reading the postings about the gear used by Cousteau
divers.  I wonder why they don't wear BCs as safety devices if
for no other reason.  The older packs had three steel tanks
and a built in regulator.  A few years ago US Divers marketed
what they called the ABS - Advanced Breathing System.  This is
a plastic case with three 30cuft aluminum tanks and a triple
manifold.  This is probably what a poster saw for sale at
Steeles in Oakland.  They don't make them anymore and they
were and still are expensive - new they were about $850 retail,
and new units still in stock go for about $600.  I've been using
a triple unit(sans the plastic case) for some time now.  I really
like the unit, and since I am short, it is more comfortable than
the 80s that bang my bum.  I also like the weight distribution of
the unit.  You can adapt a Cousteau BC to accept the unit backpack,
or you can build a simple backpack and harness and use it with a
horsecollar BC.  I'd be interested in buying another set if the
price was reasonable.

Yup, that's right. I'll probably go to Cuba next august.
Don't no where I'm going to stay yet, but it could be Varadero
or Holguin. Has anyone been diving there or elsewhere on Cuba ?

Any information appreciated immensely. Please reply by email

	A high quality, very stretchy, silicon snorkel keeper ($2.00US)
	will do a good job too.  Thread the fixed end of your BC's chest
	strap through one end of the snorkel keeper and loop the other
	end of the snorkel keeper around the mouthpiece of your "safe
	second" (octopus, etc.).

	* It's inexpensive.                

	* Almost all dive stores carry them.

	* The octopus will hang directly in front of your chest.

	Avoid looping the snorkel keeper around the tie-wrap holding the
	mouth-piece in place; it can get hung up on the cube-like end
	of the tie-wrap.  In this case, a good snorkel keeper will 
	actuall stretch enough to reach the owner's mouth (I choose to
	donate the primary second stage from my mouth while retrieving 
	the backup second stage). 

	If you choose to use this set-up, please practice it in shallow 
	water with your buddy until it's "second nature"... [caveat diver].

I spend a huge amount of time on boats but am relatively new to scuba
diving.  I have recently gotten my PADI open water diver certificate and
now have decided to invest in some gear.

I have looked through teh archives and the FAQ but have not found any
information or reviews of equipement that seemed particularly helpful.

I wandered into the local dive shop where I was immediatly overwhelmed
by a vast selection of gear of widely varying prices.  What are the
sorts of features that make one item worth more than another??? what are
the standard sorts of names and items that are reliable and generally
descent buys.

I'm most concerned about the choice of BC and regulator as these are the
most costly and most crucial items (I'm prbably not going to buy a tank
at this time).  I'm also a starving grad student, so price is an object.
I don't have any idea how the prices of teh local store compare with
others.  I've heard the local store isn't bad, but I don't know what the
items should cost.

The local shop also has a few used items.  The fellow I spoke with
suggested that I might be interested in a particular used BC in the
store.  It is a Sherwood.  The nearest thing I could make out to a model
on it was the word "Freedom".  It apeared to be in good shape.  He said
it had gone through only light use and was being sold by a grad student
who needed teh money for school.  What should I look for in used gear?
What could go wrong with it that I should be concerned about?  The
asking price on the this used BC was about that of the cheapest new BC
in the store (~$200.00).  Is this a decent price for this equipement?

The store also had an inexpensive used regulator for sale.  I think it
was a sherwood, but I've forgotten.  Same questions about this as for
teh BC.

Any help would be appreciated!

I've had much better luck with Helix (mail-order out of Chicago).  Their prices
were better than anything that I could find locally and their selection was
much better.  I recently had the pleasure of replacing an SB-103 strobe head.
All of the local retailers wanted to sell me the full kit. (Head, brackets,
cables, etc.)  Helix was able to get me the strobe head for about half the
price of the full kit.  They will also do things like ship FedEx for those
little emergencies that seem to crop up right before a big trip.

All in all, they've always been extremely helpful.

	Vicky and Andrew, 
	     I highly recommend you stay at Plaza las Glorias and dive with
	Aqua Safari.  We spent 10 days there last August and were pleased 
	with everything.  After some research, we chose a package through
	Sea Safari for the hotel and 3 dive days, mostly because they throw
	in a 20% discount on all food and drink at the hotel.  We found the
	hotel prices to be quite competitive and the food tasty.  The hotel
	is a 10-15 minute walk from "downtown" (depending on the temperature
	and humidity!) and Aqua Safari has a complete shop and boat pickup
	spot both places.  At the hotel A/S even has storage lockers for 
	your gear if you don't want to lug it back to the room.  We signed
	up for additional dives, night and day, when we got there, at no 
	price difference compared to additionals with the package.  The boat
	loads ranged from 6-15 divers, 1-2 DM's and a Captain.  The dives were
	all drift dives with moderate to strong current, 80 degree water and 
	lots to see and do.  We found the DM's to be knowledgable, very 
	friendly and flexible when defining the dives to adjust to the group
	skill levels; two really great DM's were Mario and Juan "chicken
	diver", both deserving of above average gratuities.  An added bonus
	with A/S was we could keep the rental gear and get refills for 
	afternoon and evening beach dives if we were diving the next day.  A 	        very good book showing all the dive spots is available both there 
	and in most shops here.
	     Plan on renting a car (Jeep) one day (about $80) to drive to the
	other side of the island, just to see the contrast.  You can stop at
	the ruins in the middle of the island, but be warned of the biting
	ants and mosquitos!  Transport otherwise is well taken care of by  
	taxis or feet.
	     Others have responded positively to your Hotel Barracuda inquiry,
	but it looked quite run-down from the outside and maybe not even open
	for business to me.  If you're in the mood for a good old fashion
	American hamburger and french fries while you're there, don't miss
	"The Sports Page" restaurant; be sure to bring a homegrown team jersey 
	to add to their collection!  
	     Have fun and make new diving friends,

While this topic that I'm about to bring up isn't Scuba in the normal sense
of Scuba diving that most of us do, this does seem to be the most
apporpriate board for this.

In a recent issue of Outside magazine, they did this article about a guy
who wanted to do some diving in the world's deepest cave system. His
problem was that all existing scuba technology did not allow him enough
downtime in the water. So, he scrounged up a few million dollars, did lots
of reading, designed and built a complete closed, rebreathing system.
Because this was potentially BIG money yet to be patented, the article
writer had sign a confidentiality form indicating that he would not write
about the technical aspects of the system. 

My question: has there been any more information? Does anyone have any idea
how a system such as thus might work?

This guy does have a several working models; it's probably well beyond beta
testing. The pictures of it look pretty high-techy. The inventor said that
the whole thing has redundant designs in it for safety and is driven by
several computers. From what I remember, the system takes a diver's
exhalation, remove the CO2, and recycles the rest back into the system
again. I think he calculated his system to be able to support dives
measured in the teens of hours (13, or 16).

NASA and US Navy apparently very interested.

Lyle,

I do indeed have a bad back (I had surgery last year) and have been diving
both
before and after the surgery. My back had been a problem for several years
and
it finally reached a point where I was basically as limited in motion as a 
harbor seal on a large flat rock (ie. it don't get much worse). Anyway, as
far
as the back goes, the only worry I have is about adding 50+ pounds of tank
and weights and carrying that stuff around (I doubt the weights are much of
a problem when worn as they stay on the hips, well below the injured spine,
but when you take them out of the trunk or move them around by hand, they
are heavy enough to injure).

So, my feeling is that if you don't reinjure youself moving the gear
around, you can probably dive with impunity. I have experienced no problems
from diving (although I have no medical information on back injuries and
diving, actually) other than those of moving heavy gear around.

On a side note, I feel that it is advisible that you find a doctor who does
know about the effects of SCUBA and pressure and ask. I'd be interested in
the response myself. My guess is that since discs are merely cartiledge and
some sort of compressible jelly, the back sustains the same stresses while
diving regardless if there is an injury or not. 

All I can add to this medically is that after my surgery, I asked the
doctor whether there were any restrictions on my behavior once the back
healed (I listed the things I do, kayaking, swimming, SCUBA, water polo,
softball, etc.) and he said. "No. The incision is closed with glue, so you
can get it wet. Just don't lift any weights over 20lbs for about a month."
I went swimming the day after my surgery (I stopped by the pool on the way
back from the hospital) and haven't any real problems since.

never been in water deeper than my kitchen sink (to activate it). The unit
was purchased for about $600.00 local. I am asking 520.00 for the unit
and will pick up the shipping inside the continental U.S.

The human auditory system uses two methods to localize sound.  The time
difference in the sound striking the ears and an intensity difference due
to the head.  The head provides a shadowing effect for small wavelength or
high frequency sounds. The low frequency sounds are localized by the time
difference.  The question that would need to be answered is would the head
have to be enlarged five times or no??  There are lots of factors that go
into sound localization.  Which is why I wanted to make the poiont that
sound localization under water is not a learnable skill.  However it would
be interesting to develop a system to hel a human localize sound underwater
