Been to Koh Tao, should I go to PERHENTIANS?

Hi,

Last year I spend a few weeks in Koh Tao (Thailand) diving.  Loved
every minute of it.  Beautiful environment and very cheap.  Good food
and massages too.  Also a great place if travelling solo as there were
lots of other single travellers/backpackers.  But now I'm looking for
this years diving destination.

Has anyone been to the Perhentian Islands in Malaysia recently?  If so
where did you stay and what dive company did you use, and how did you
find it?  I'll be travelling alone so would prefer to avoid the
couple/family type resorts.

Are the Perhentians likely to be the right pick for a sequel to Koh
Tao, that is a cheap, backpacker-ish dive-centric holiday in SE Asia?

Lots of people i guess !!!!!!!!!!

Sorry about that, i was (last week) recently in Sabah, and there were a
couple of backpackers staying with us who had come from the Perhentians,
they were saying how good it was.

I dont think they were comparing at all, they were merely saying that they
had a really good time there  and they enjoyed their dives.

How can anywhere compare to Sipadan/Mabul and be better ?  ;^)
Thinking about it........i guess Chuuk or Bikini is better for Wrecks..

I don't think that's quite what chilly meant.....

Easily. Try diving Palau!
After Palau, Sipadan and Mabul are almost boring... almost. :o)  
Actually, all three offer different types of dives, so there really
isn't valid grounds for a generalization, but there is no doubt that
diving the Perhentians is more interesting than diving Koh Tao. And
personally, I love diving Koh Tao.

The Perhentians provide more varied marine life, more live coral, and
generally better viz than Koh Tao more often. If those three are
important to your dive then the Perhentians are better.

Or Coron Bay in Palawan Province in the Philippines. Six WW II wrecks
all divable with nitrox, and no need for the expense of a live-aboard.
$26 a day for an air-con double with ensuite in Coron Town, and a short
boat ride out to the wrecks.

I was looking for a response, my wife is wanting something different after
5 trips to Mabul/Sipadan in the last 2 years.
You kindly provided a link to your Sangalaki report a short while ago
which i duly booked and was looking forward to........sadly the trip
did'nt come off, we got as far as Tarakan in Kalimantan when the
Indonesian immigration stepped in............
We had done 11 nights on the old "Rig" (Seaventures resort is an oil
platform used as a diving resort) situated just off Mabul and then were
supposed to do Sangalaki.
Off all the places we have dived, a few now i guess, underneath that "old
Rig" is by far the best, for us anyway, while there we dived Kapalai and
Mabul just once and never even went to Sipadan which is only 15 min's by
boat. Every dive under the Rig is a different dive with different
creatures to see, the Macro oportunities are endless, we just love it.
Having said that, and as i say above, somewhere new is what we are looking
for.

> Actually, all three offer different types of dives, so there really
> isn't valid grounds for a generalization,

Agreed, diving is a personal thing, what suits one does not suit another,
luckily my wife dives and we are buddies and we get turned on by the same
things (comments not required).

Sounds good allthough we dont do nitrox........we did'nt use or need it in
Chuuk, allthough we did do three stops on the way back up, do you have to
use it in Coron Bay ?

Just out of curiosity, why don't you "do" nitrox?

In Chuuk, nitrox came in very handy to extend my bottom times, giving me a
total of at least 5 additional hours underwater during my week there.  Five
hours for the $100 or so most boats charge for unlimited fills is a good
deal anywhere.  Having traveled all the way to Chuuk to dive, it's almost
priceless.

> Just out of curiosity, why don't you "do" nitrox?

I guess its a long story, probably one of ignorance, but when we got our
Padi cards in 98 we just went off on our own diving the UK, we were not
part of a club or group so the natural progression thing never came up, we
saw so many people or talked to them where they would say they just
qualified and were now going to do divemaster or instructor course, we
just wanted to dive and never saw the need to brag about how qualified we
were, and it was the same with Nitrox.....lots of divers we see wont get
in the water without their "fill"....."i must have nitrox" they
say.....christ were in a group doing the same dive, 20 metres at most, get
a life........i understand the saturation issues, bottom time, tiredness
but it has never stopped us doing the dives we want, i also think that it
can be very restrictive.........but not having used it i cant really
comment too much. Thats why we have never bothered with it.....

> In Chuuk, nitrox came in very handy Having traveled all the way to Chuuk

We were on Thorfinn and if i remember, it was quite expensive........there
was one other couple on board with us, from the UK and they were not Padi,
they were certified by that far far better organisation........they must
have been better divers than us because they had every conceavable dive
aid i have seen, i thought they were going mountaineering because they had
ropes, metal thingy's for climbing rope, hang tanks, whistle's, bell's and
anything else you could hang off a d ring......i never saw them penetrate
any of the wrecks though ????, so for me, fancy titles and qualifications
mean very little........and when i get asked "what qualification are you"
it makes me chuckle.....

I don't do nitrox because I don't think it is worth the cost of taking
the lessons, changing my computer, and buying nitrox.

What's true in Truk is not necessarily true elsewhere.  I did a
similar calculation after diving off Mona Island.  My conclusion was
that had I spent $150 for nitrox, I would have gotten 75 more minutes
of bottom time.

> What do you mean? What happened?

I was asked the same question in a local UK scuba conference, this was my
answer,

> Did they explain why? I take it your Indonesian visa was in order?

They did explain, we didn't have a visa on arrival ????????? but my office
manager was there in April and he got his visa by filling out the
immigration card on the flight out there (the flight was on a small
Twin Otter, 18 seats) and getting the actual visa put
in the passport AT immigration on arrival ??????
We arrived there on the 7th !!!!!! (London Bombings) dont know if that was
significant ?
When they confiscated the passports there was a lot of people badgering us
and asking lots of questions, very stressful for my wife who was worried
about me......(two heart attacks the day after arrival at Mabul
last December)......after a while they put us in a car and took us of to
an immigration center/office where we had a dressing down and a question
and answer session, we did not know where we were......after that they put
us in a car and we were driven to a hotel (the Makmur in Tarakan
which was cheap and quite nice) (yes we had to pay for the hotel)where we
were told we would be collected the following morning at 7am, at 7am we
were ....then taken to the
local port (still no sign of our passports) we had to buy tickets for a
local ferry then given our passports and put on the ferry back to
Tawau...not a ferry that you or i visualise though..........the ferry
consisted of old airline seats, two seats on the left, a tiny gangway down
the middle and then another two seats on the right, the boat was quite a
fast boat, very long and slim, the journey back to Tawau took 3hrs, but
getting through the Malaysian immigration at Tawau was going to take
forever, at the dock the ferry could not get to moor properly so we had to
clamber over 5 boats to get onto dry land, this with hand baggage, laptop
bag, camera, photo case and dive bags was not easy.....the story goes on
and on but i wont bore you with that now........

We did dive in the Tunku Abdul Rahmen Park in KK, we were told it was
crap, just sand and not worth the bother but we wanted to get wet so we
tried it, we really enjoyed it, Janet was fing Nudi's that we had never
seen before, (no camera with me as it was supposed to be crap) we were
even
showing the guide little nudi's that he had never seen before......he was
amazed......so the two dives we did there were allthough expensive very
good.

On the way out from the UK we flew to KLIA via Dubai with Emirates, we
wont go with them
again....seats are crap on the Airbus 300's, check in staff very pedantic
and want to charge for excess if you are 1 k over......and at £30.7 per
kilo our excess on the way back would have been close to a thousand
pounds, hence me getting FedEx to take my big dive bag from KK to here for
£200.
I wont go to Sangalaki now , it is remote, even Sangalaki dive lodge
said they could not guarantee to get us there over the weekend even if we
got a visa on the Fri afternoon (which we did) so it would be Mon before
we "might" get there, and coming back on the Thursday gave us no dive
time. We could see problems arrising with ferrys and planes on the way
back........and just thought that enough obsticles had been put in our way
and something was saying "dont go".......it makes getting to the Rig a
picnic.
Sangalaki is guaranteed Manta's......lots of them.........and lots of
macro too.
Its owned by a guy called Ron Holland, he took it over when Borneo Divers
pulled out, he was with Borneo Divers for some years i understand, and he
hails from Manchester in the Uk.

Wow, what an experience!

Where did you enter Indonesia?  Did you pay for your visa upon entry?

For example, upon arriving in Jakarta, and upon entering the airport from
the causeway, there's a booth set up.  You line up and pay for your visa
there and then proceed into the airport to pick up luggage, immigration,
customs, etc.

Was that the only way back, or the only way they would allow you to go back?
Why couldn't you go back the way you arrived?

Sometimes things work out the way they are supposed to.  It's just that it

I'm more confused now.  Do you mean to say that you will *never* go to
Sangalaki? Do you mean to say that it is too difficult for most any of us
coming from halfway across the world?  Or are you just saying that on this
trip, your attempt was so much trouble and your experience has tainted the
idea of going there for the time being?

> Wow, what an experience!

We have an "experience" on every trip............no one will travel with
us.............

> Where did you enter Indonesia?  Did you pay for your visa upon entry?

The whole trip was...........UK to Dubai, Dubai to Kuala Lumpur, Kuala
Lumpur direct to Tawau (Tawau is in Sabah north Borneo) on Air Asia, Air
Asia is VERY cheap, from Tawau we are allways met by Seaventures staff
with a minibus and then driven the 70 or 80 km to Semporna wher we get the
speedboat out to the Rig. 11 nights on the Rig then fly by a Twin Otter
(18 seater) to Tarakan in Kalimantan Indonesia, then connecting flight to
Berau then boat out to Sangalaki for 7 nights.........that is what SHOULD
have happened.

Before we left the UK our agent in KK (Kota Kinabalu) told us there was
some problem with transport back from Sangalaki and we could only do 6
nights there, in other words we would have to come back a day early and
that would have to be by ferry from Tarakan to Tawau.

I had been to Indonesia before and thats how it was, also my office
manager was in Indo in April and he says it was like that.
The Immigration officer said that it was "NEW" regulations........someone
told me that it was a retalitory measure against the "west".......


> Where were you when your passports were confiscated?

We had just landed in Tarakan........and had expected to hand over the
immigration cards (the ones you fill in usually on the plane) and get our
passports stamped, apparently not so.
This is when all hell broke loose, officials spoke a little English but
not much, (i am never critical of foreigners who cant speak English
because they can usually speak more English than i can speak their
language) there was about half a dozen of them wanting "VISA" "VISA"

The agent who was supposed to meet us finaly turned up and was very little
help as well as being the most miserable sod, at this point i rang my
agent KK who said she had just had a phone call from Sangalaki to tell her
that the connecting flight we should have been on at Tarakan was over
booked and we would have to stay in Tarakan overnight, i then told her
about the "VISA" demands, she said that she was never informed about visa
requirements when she booked Sangalaki for me, and it was the first she
had heard about it.
At this point the immigration officials put us in a car and took us off
into the town to the immigration offices..........

I was ok though, allthough my wife was clearly frightened by all that was
going on.

This is what i tell my wife........she says that she can find other
stories to tell our grandchildren of which we have 4.

> back?

It was the only way back, the flights from Tarakan - Tawau only go twice a
week IF they run to schedule.

> Why couldn't you go back the way you arrived?

The plane that dropped us off literaly turned around and took off again,
so it had gone before i knew what was going on otherwise i think i would
have got straight back on it.
This was all happening on a Thursday, so.......we had to stay in the hotel
in Tarakan overnight and get the ferry back on the Friday morn....we
finaly get into Tawau at lunchtime on the Friday, at this point we are
still thinking we are going back to Sangalaki, so, Friday at 2pm we arrive
at the Indonesian consulate to get our visa's, after an hour of waiting
they ask us to fill some forms in and then ask for our
"photograph's"....photos i say......yes two passport photo's each they
say...........by now this is 3pm and they close at 5pm......so offwe
trudge......no taxi's in sight so we have to walk in 30+Centigrade...and
find somewhere that will do our passport photos...........after getting
our photo's done (long story and so funny) and a well deserved "whopper"
at a burger king we arrive back at the consulate at 4.15pm.......we pay
our money and walk back to our hotel with our passports stamped with a
nice looking visa............
As things stand we are do to catch the ferry back to Tarakan on the Sat
morning at 9am......remember it takes 3 hours for this ferry to do the
journey that makes it around 12 when we dock, if its on time ?????
But no, we are told the Sat ferry goes at 12:30pm which makes it 5:30pm
when it arrives in Tarakan......too late to take the next boat to either
Berua or Sangalaki (never got to find out exactly where the boat went
to)as boats dont travel after dark for fear of pirates....yes....pirates.
This meant it was now Sunday..........and nothing moves on a Sunday so it
was going to be Monday before we would get to Sangalaki.......and as we
were due out of there on the Thursday it meant that Wed was the last dive
day....and even then it meant travelling with wet dive gear......not
something you want to do........
At about 6pm on the Friday evening we had a phone call from the offices of
Sangalaki Dive Lodge in KK explaining that they could not guarentee to get
us to Sangalaki Island till late on the Monday........it was there i said
that it was not worth all the effort for two days diving......

So........in a nutshell, thats about what happened on this trip.
Disaster appears to follow us around, or i follow it, we have either just
been to or just left Bali and the bombings there, the hotel bombings in
Manilla, booked flights through the states when 911 happened, the Massacre
at Luxor Egypt 97, while driving in Spain in 97 we had a truck come
through the central reservation and hit us HEAD ON, we were in a little
"tourist" car......my wife spent a deal of time in a spanish hospital
after that.......

sh.t happens i say...........and there is allways someone worse off, when
these things are happening to us we tell ourselves that at least we are
telling the tale, others are not so fortunate........others dont even get
the chance to experience what we do.

Yes......my wife says that she wont go.

I'm not saying that it is Too difficult to get to, but at our age (I'm 54
and my wife is 51) lugging 70 or 80 kilo's around in difficult
circumstances is not condusive to a great enjoyable trip. No, she just
wants me to organise trips where we can get on......and off a plane and
then dive..........not a lot to ask i guess.
Anyway i care about her so dont want to cause her grief if i dont have to.

> Or are you just saying that on

Well i never say never so i think that is a good way of looking at it.

I think he was there from the start........

I suppose everyone has now heard the news about Sharm on the Red Sea
??????    thats another of our dive locations, we have been there 7 or 8
times in the last few years and have friends there that run a dive center.

You never 'need' to use nitrox. It's a bonus for your dives in terms of
bottom time.
There are several reasons why you should have nitrox certification. (And
the course is little more than learning the math and safety factors
involved, not new diving skills.)
Primarily, it gives you a MUCH longer bottom time at certain depths.
Secondly, it reduces the surface interval required between dives as
there is less nitrogen entering your body during the dive. And third, as
a result of the shorter surface interval need to off-gas (less nitrogen
in the body to begin with,) you can make more dives safely in one day.
The main drawback is a limited usable depth, however in Coron Bay, as
every wreck sits on a 100 foot (aprox) bottom, you can really extend
bottom times.

Here are some old photos shot in Coron http://seatraveler.com/coron.htm 
The viz was pretty bad that week.

Anecdotally, many people state that they are much less tired after a day
of nitrox diving, but there is no scientific proof of this. You can do
the nitrox course while doing your regular dives as it only involves
some book work to learn the proper increased percentages of O2 in your
gas and the bottom times for each different mix, how to analyze the
final mix, and how to compute the depths and times. Then, of course, you
can buy a nitrox computer and let it do most of the grunt work. Instead
of diving 'air' at 21%, you have the choice of increasing the O2,
generally not more than 36% (although you can go higher) and because
there is more O2 there will be less nitrogen. Less nitrogen loading
leads to longer bottom times. Longer bottom times lead to big smiles on
great dives! You can do the course in two days, and dive nitrox while
doing the course. Nothing lost from your vacation time except a few
hours in the evenings, and gaining bottom time for all your dives.

Yes, i understand all that.............must admit that some of our dives
under the "old Rig" did drag on into deco, we were doing a lot of 60 to 70
minute dives at 18m which is bottom under the Rig.

Four dives a day is usually plenty for us, and i hardly get enough time

I think you are looking at this from the wrong perspective.

It's not about the time, it's about the safety.  In the same amount of
time, you have much less to off-gas if you're diving Nitrox.

In just two lines, Don managed to contradict himself!

Of coures it about the time!  If you have much less to off-gas,
then it takes much less TIME for the "mandatory" SIT for the next
dive.

More like "safety trade-off".

True, you can dive Nitrox on air tables and not approach the deco limits
as closely and thus be "more safe".  However, the risks from Ox-Tox and
the risks of someone pumping the wrong mix are increased, so its really
just a big safety trade-off.

Besides, if your BC isn't O2-cleaned, it can spontaneously explode :-)

No table or EAN is "safe" for grossly obese (short of morbidly obese)

What if you're diving dry and you "off gas"?  Does the increase O2 %
increase the risk of an explosion?

You don't have to dive Nitrox on air tables to decrease the nitrogen loading
in your system.  You can, in fact, dive beyond what your computer would
allow on air and still have a lower nitrogen load.

As for the toxicity, while the risk certainly moves to a shallower depth
when you dive with more than 21% oxygen, the risk of O2 toxicity is just as
real on air as on nitrox.  You simply stay above the MOD for the gas you're
using.

Methane and a high percentage of oxygen could be a dangerous combination,
but would probably require a spark to set it off.  Assuming you don't fart
sparks, the chance of an explosion is low.

Tox is merely one of the risks...sorry, I oversimplified.  There's
several very small risks from switching from "just air" to "modified
air" if for no other reason than there's incrementally more process
steps in managing a tank of Nitrox versus the air baseline.

What this comes down to is the question of trading-off one very small
risk versus a sum of other (probably smaller) risks is worthwhile or
not, which will ultimately depend on the personally-weighted value of
the benefits of doing so.


In the specific case of using Nitrox on Air tables, the classical
benefit of longer bottom times is not utilized.   In addition to
whatever risks, it costs more money, both in mix and in equipment, so as
such, I don't see the significantly perceivable benefit that
sufficiently outweighs these factors so as to reasonably justify its
use.  YMMV.

Call me overly cautious, but even when I'm using plain old air I try to avoid farting
in my BC. After all, someday I might actually need to use the oral inflator.

For mixes below 40%, the answer depends on how gullible you are in

Obviously we hav'nt fallen into the "gullible" trap yet then !!!!!

Seriously though.......its reading and listening to these kind of
discussions where there are arguments on both sides that make me and my
wife wonder and think "is it worth the hassle" ?

We have done about 500 dives since 98, most of those around the world in
warm water and down to depths of 60m (in Chuuk), all this has been done on
12ltr singles and air,it has not caused us any concerns, during intensive
dive trips we dont fall prey to the "dive dive dive" routine, we prefer
quality to quantity.........4 dives a day is usually plenty for us, and if
we see dive times shortening because of overloading then we miss one and
just chill for a while. So we ask ourselves "has it caused a problem, has
it prevented us from doing what we wanted to do, do we need the extra
hassle", no i dont think so. Air we can get freely at any dive center,
nitrox is not available freely at all the dive centers we have dived with.

I guess we wont get blown up just yet...........but.... farting underwater
is'nt a hazzard is it ????????????

Well, you couldn't dive with EAN 36 down to 60m for long.
My Uwatec Nitrox Pro survived a 196 fsw bounce dive I did on air,
(can be found in the archives) because I had forgotten to reset it
to EAN 21.  That fact didn't come out until one Crusty (whom I
had kidded for months about diving with a Cochran) noticed that
my Uwatec played dead the last dive of the liveaboard trip --
which was 10 dives after it survived the 196 dive, and the
CUMULATIVE effect of having done that dive finally caught up
with the computer algorithm.  :-)

That sounds like dive, dive, dive to me!  :)  My all-time record
was only 7 dives in one day, but all shallow, when the Owner of
the Scuba-SE list, Jeff Kell the Trumpetfish, dived with me for a
week in Cozumel. doubling his lifetime total in dives.  :-)

PADI has gone a long way from it's position of "no no" on Nitrox to
its present "yes yes".  EAN is available in nearly ALL of the
liveaboards
I've dived the past 10 years (about 30?), and hardly on any before
that.

Putting numbers on is the wrong way of looking at this i think, we do it
because we £ove it so we do what we want, we dont want it to be hard work
or a chore, sometimes the 6am dive from the boat can be just that,
other times we have looked forward to it, it just depends on the
individual, we love our night dives and allthough we dont plan the day
dives around that we make sure that we can do them when we can.
Night dives are especially good as the stuff that comes out at night is
fascinating, it makes for some great photo shots too.

Generally, I agree with you.  Most times, nitrox is an advantage because it
allows me to spend more time underwater on the one, two or three dives I do
a day.  When there's a reason to do an agressive series of dives, however,
nitrox helps one to do it safely.  FWIW, all of my 7 dive days were on a
spearfishing and lobstering liveabord.  The chance of success at both
activities are enhanced by covering a lot of territory.

Yes, I spearfish when diving.  No, it's not unsporting.

Personally, I think that it is 'worth the hassle' for some dive
profiles.  However, by the same token, I also think that it is also
oversold at times too.  The challenge is recognizing where and when it
is of value and ditto for where/when its not.

For example, I can recall a diver who was going to be going to the
Little Cayman resort that promotes the use of Nitrox.  However, when
you look a bit more closely, you find that because the Resort runs a
2/AM + 1/PM tanks/day operation that routinely rushes the 2 AM dives so
that they can be back at the dock for lunch, the implications are that
these forced short duration AM dives would derive effectively no
"longer bottom time" benefit from the use of Nitrox.

Since the Nitrox wasn't free (IIRC, it was an additional charge of $12
per tank), it clearly was a pure waste of money for the consumer.
However, this doesn't stop the Dive Op from promoting it, since they're
the financial beneficary of the transaction.

Or, sometimes, reducing the hassel to the point where it's insignificant.
When you and I dove, there was no hassel.  I simply picked the tanks that
had a gas suitable for the dive we were planning.  When we were done, I had
them refilled with the same.  I normally keep a few tanks with 36% and a few
with 32%.  The only time I don't have what I need is the rare occasion that
I'm planning to go beyond the MOD for 32%.  Usually, it's no hassle at all.

Of course, if I'd known we were going to do the Castor and that Curtis was
going to bring doubles, you can be I would have arranged to use my 100s
instead of my 80s.

That happens.  On the other hand, many resorts allow unlimited shore diving.
It's possible that, even with the rushed boat dives, that nitrox would
provide some advantage . . . or not.

Resort diving is a tough question mostly because you almost always have to
pay more for nitrox.  At home, I actually pay less.

Wow !  That's quite an increase.

The liveaboard boat I'll use next month charges about $50 extra fro 32% from
their on board membrane system.  We normally do 16 or 17 dives over the 2
1/2 day trip.  The combination of a very agressive dive schedule and
relatively low per dive cost make it worthwhile for me, but not by a lot.
Because my buddy does not use nitrox, I'm limited by his available no deco
time.  What I get is the ability to stay deeper, which is my preference,
longer while he stays shallower, which is his preference.  It works out for
us.

Then again, it was an air fill that was supposed to be nitrox, on the same
boat, that got me bent a couple of years ago.  If you're going to be stupid,
which my failure to check my gas every time was, you have to be tough.  My
damned elbow still bothers me.

Thanks for mentioning this (I wasn't going to bring it up otherwise):  
not to downplay what happened, or any of the reasons, etc, etc, but I do
think that it does serve as an example of how there's more opportunities
for errors to occur when a process becomes more complicated...its an
example of one of the "many tiny risks" that are part of the trade-off.

And like with anything else in reality, no example is going to be
"undergraduate textbook" perfect: since the filler had both air & mix
available,  the air diver was also subject to an objective risk of
getting the wrong mix too.  While it wouldn't have increased his risks
of getting bent, it would have changed his MOD for that dive, so he
could have unknowingly run into trouble with that.

And if your doing 30 to 40 dives on a trip thats roughly $480 for the 40
dives EXTRA per person.......christ I've had a week in Bali for the pair

Don't be so quick to judge Nitrox just because I provided one example of
where it was a very poor value.  

For example, I did a trip to the Galapagos in 2002 and while I forget
exactly how much it all cost, I do recall very well that we blew through
$3000 just for the airfare & hotel transfers to get there/back.  

Add to this the cost for two diver-weeks on a liveaboard, and you're
probably talking another $5K there (probably $6K), so you're easily over
$8000 for the whole trip by the time you're all done.  

If we say that we did 20 dives @ 50 minutes each = 1000 minutes of
diving for $8000.  And $8000/1000 minutes = $8.00 per minute.

This operator's cost to upgrade to Nitrox was quite reasonable.  I think
it was only something like $100/pp for the week.  So we add another $200
onto the cost of the trip...its a small 2.5% cost increase.  YMMV on
where to go from here, but one way to hash it out is to say that for the
Nitrox to be "cost effective", it would have only needed to have
increased bottom times by more than the total trip's increase in cost:

Assuming that the Nitrox gave us 10% more bottom time, the average 50
minute dives became 55 minutes:

Same 20 dives, but now @ 55 minutes each = 1100 minutes of diving for
$8200.  For $8200/1100 minutes = $7.45 per minute.

It's not entirely about money.  Most of us can't just go diving any time we
like.  When we can make time, we like to maximize the amount of time spend
actually diving.  Nitrox is good for that.

The fact is, nitrox may not be for everybody, but there are enough people
diving it on a regular basis, to suggest that there's some value to using
it.  At the very least, it's worth the time to learn more about it.

If the currency used is the Euro, the "equivalent of one dollar"

Easier just to say:  5 extra minutes times 20 or extra 100 minutes.

At WHATEVER per minute cost, if morgan's air consumption rate is
good, he could say he saved a BUNDLE by diving air on the eaverage
of 75 minutes per tank.

He would have had 35 x 20 or 700 extra minutes AT NO COST for Nitrox!

YMMV.   I am just playing the Devil for morgan!  :-)

Dave, it has been my experience that most diver operators offer a heavy
discount for a weeks worth of Nitrox.  I'm doing the Caribbean Explorer
II this fall and they offer Nitrox for the week at $150USD.  I will take
that option.

My diving is much like yours.  Warm water vacation diver, and I find
Nitrox a real plus.  I like the added safety margin and do feel that it
cuts down on fatigue.  But the fact is, Nitrox hasn't changed the way I
dive at all.  I was never an aggressive diver on depth.  I do enjoy long
dives and perhaps by the 5th dive, I'm getting more bottom time but I
really haven't notice any big changes in the way I dive.  For me, it's
all about the safety.

Of course, I use a Nitrox dive computer, and mind the depth (which for
me isn't much of an issue because I like to take pictures and most
subjects are not deep).  I know many divers will do the first dive on
air and the rest on Nitrox.

The courses are straight forward and it really isn't a difficult thing
to pick-up.  Some here tend to make much too much of it, as they do
diving in general -- don't let them put you off.  It's scuba diving, not
space walking. ;)

Dive safe,

You are getting more bottom time and it's safer?  How can both be

You know the answer to this.  You just didn't think about it right.  It can
be safer because the same dives, done on air, would require decompression
or, in a more traditional sense, it can be safer if he extends his dive time
a bit, but not to a point equal to the DCS risk he would have been taking on
shorter dives done on air.

It depends on your preferences and how much of a hassel it really is.  I use
nitrox on any dive except when I'm going to be deeper than I'm comfortable
using nitrox.  It's not a hassle for me, my computers are all equipped for
it and the shop that does my fills gives me anything from 21% (clean air) to
100% for a lower net cost to me than what I would have to pay for air at
some shops.  They do this by charging me by the cubic foot rather than by
the fill.  My tanks are rarely less than 1/3 full.

When people ask me whether they should use nitrox, I generally respond that
it depends on the advantage you get from it.  I don't consider diving air
tables on nitrox to be a significant advantage.  The air tables/computers
are safe enough for me without the reduced nitrogen loading nitrox offers.
Increased dive time, however, is a significant advantage.  When your
consumption improves to the point where you consistently surface because
you've run out of no deco time (or as much of it as you think prudent)
instead of because you've run out of gas, it's time to consider nitrox.
Nitrox allows you to use more of your available gas by giving you a longer
no decompression time at the same depth or depths.

Why not get the training, give it a try and then decide if it's something
you wish to use for most dives.  At worst, you'll learn a bit more about the
physics and physiology of diving.  At best, you'll increase the time you get
to spend actually doing dives.

You'd better hope that they never figure out that it costs significantly more to pump
the last 1/3 than the first 1/3.

It doesn't cost them more. They specialize in gas fills.  They bank 32%, 36%
for sure and probably 50%.  They make money from what most shops claim is a
loss leader and save me money in the process.  Based on the people I see
going in and out of the store, I suspect that I'm not the only one that
appreciates what they're doing.

I guess this is a 1 to 10 wish list......

Senotes/Cave..........Yucatan/Florida
Wreck's...............Chuuk/Bikini
Easy relaxed diving...Red Sea
Big Fish..............Coral Sea
Wall dives............PNG
Muck dives............Indonesia/Malaysia

I have not dived the caves or springs in Florida or the wrecks of Bikini
but i read magazines..........

So i guess the Galapogos should be up there......

Its probably like asking whats the best wine.........it depends on your

Next time, please quote a bit more.  I'm not sure what this all refers to.

If it's the quality of diving in Florida, I tend to agree.  We have some
truly world class diving, but as I posted to rec.scuba just a few minutes
ago, there are better choices if you don't mind spending the money to
travel.  I suspect that more dives are logged in south Florida than anyplace
else in the world, but it's not because it's the best in the world.  It's
because it's the best that Americans can drive to.

Probably both.  But Lee doesn't follow ME because I find too many
or his errors and self-contradictions.  He pretends to be a
Ostrich.

Lee first argues that Florida diving is world class (to those
little frogs who live in Florida;  or else he meant world class
of the WORST).

Now he says it's the best that Americans can DRIVE to.  That's
not even true, if he said it's the best the Americans can BICYCLE
to.

Folks in Texas can DRIVE to Cozumel, Belize, Honduras, and the
rest of the Western Caribbean that have much better diving than
Florida.

Folks in the Left Coast have BETTER dives in the kelp forest
or the channal islands within the USA, and can DRIVE down
Tiajuana and the rest of the Western Mexico and Central
America dive locations.

Lee sounds like the guy who walks into the bar and waid he
could whip anyone in the world;  then backed down a bit said
said he could beat anyone in the State:  anyone in the County;
anyone in the City ... until somebody in the bar all that time
flattened him.

"Reef Fish" <Large_Nassau_Grouper@Yahoo.com> stated a lot:

Hang on a sec Bob,
You've obviously got an axe to grind against Lee.  Keep me out of it.  

As I've stated on rec.scuba I've been lurking for a long time (rs, rsl and ukrs [rse never really seemed worth the
effort])and been content to watch and learn, it seemed there wasn't a lot I could say that hadn't been covered
already and even if I did have an answer to the question(s) the timezones usually meant that the answer was there
before I'd logged on, so my input became worthless.  

Now I've stuck my head above the parapet I'm not going to get involved in any petty arguments; next thing you'd be
hearing is "Innocent Civillian gunned down in cross-fire!".  If I can make an informed response, ask a dumb
question or serve a little humour, that's enough for me... for now at any rate.

He's in my kf too. But this exchange looks somewhat interesting.  I wonder
if I should let Bob out of the "box".  Hmm, what to do, what to do?

Lessee now, Stef said he didn't want to get involved in a petty spat. So,

You odn't have to worry about Greg.  He usually had too much

and a poofter!

Is it OK if I call you Steve instead?  I had a crush on a friend's sister in
high school named Stef.

You know how girls are nowadays.

Besides, my middle name is Stephen, so I suppose you could shorten that with
"Steph".  Perhaps that's why some girls are named Stefanie, so people don't
pronounce their names like "Steve-anie".

In any case, you have a lot of proving yourself to do before I can consider
you "one of the guys".
