Natural selection in action. Anyone diving to 165 feet or deeper should
have enough sense not to bolt to the surface from that depth, especially
over such a minor problem. Obviously that is the worst thing to do.
An immediate but controlled ascent, even extra slow and with extra
decompression stops, is called for.

It scares me to think of people like those involved is this incident

I have done this myself in Wisconsin.  Be prepared for 0 visibility and 
strange looks from golfers.  Also be prepared for the golfers who walk up 
to you and insist they lost a ball the week before and want it back.

I never made any money for this, but the golf course did pay for my 
equipment rental.  As a new diver, I was looking for cheap ways to build 
up some bottom time.  I guess the total value of a day's work was forty 
dollars (that's what the equipment cost).

I live in Florida now, where the wate hazards say, "Danger - Alligators".

Needless to say, I've retired from that "career."

I use the Navcon cconsole with a DataMax Sport as my computer.  I find
that the setup works pretty well.  The hose is long enough to allow me to
get a good bearing on any object I need to (or take a heading) without
a struggle to get slack from the cable.  I also got the neoprene cover
for the console.  It keeps it from getting banged up in my dive bag,
and it just looks really cool :)

I dive with 2 monitor2's (one console, one wrist), and I've had a wide
variety of "wierd things" happen with them.  Since the Monitor2 is from
the same "bloodline" (same s/w, same h/w (?), different packaging) I
thought I'd post you a follow-up:

After a dive two years ago I was washing one of my monitor2's in
warm, fresh water whereupon it started an altitude dive.  I think this
was caused by a combination of low battery and the warm water, but
who knows?  I sent it back, along with a description of the problem,
received a phone call from the service people, and they posted me a
new one overnight.

I had another Monitor2 whose pressure transducer liked to think I was
at the surface (following a dive) when, in reality, I was at about
12 to 15 fsw.  I sent it back too, and received a new one.

I suspect that both of these problems were the result of marginal
batteries.  The latest batch of Monitor2's I'm using have been going
for about 10 months without anything really wierd happening.

The most common problem I've had (and it's documented in various books
such as Gary Gentile's "Ultimate Wreck Diving Guide") is a failure to
go into log mode after dive termination.  This has happened to me
many times, even after repeatedly drying the contacts.  I suspect
moist air, fog, mist (whatever) to be the culprit.

Yesterday I pulled out my Aladin Pro to go for a dive to find it
was already in the middle of one.  Some time since I packed it away
a fortnight ago it started a dive with a 65.3m maximum depth, and it
is now at 3.2m  Given that the dive timer has obviously clocked around
a few times this was probably a wise deco stop.  When I put it in the
water it registers depth changes correctly, but is seems to have lost
its idea of zero.  It goes in for a repair this morning, but has anyone
on the net had a similar problem with an Aladin Pro?

Just so you know....

Most Rolex watches (including the Submariner-Date and Sea-Dweller)
are mechanical watches.  Although they are very tough and very, very
watertight (the Sea-Dweller on my wrist is guaranteed waterproof
to 4000 - yes *four* *thousand* - feet), they are not as accurate
as cheap quartz watches.

The Submariner-Date and the Sea-Dweller are "Superlative
Chronometers" and are "Offically Certified" (by the Swiss)
but are still only guaranteed to -1 to +8 seconds a day.

Like I said, for a mechanical wrist-watch, thats very good,
(and good enough for any dive) but you'll get better day-to-day
accuracy (and probably "good enough" water protection) from the
cheapest kids "divers" watch from any local store.

Of course, you don't get the neat "flip-lock" bracelet :-)

On a related note, I too need vision correction and do not own a prescription
mask.  What I do have is an old pair of glasses (actually they're plastic)
where the lenses kept popping out of the frames.  They are the same
prescrioption I use now and I am wondering if anyone knows of a glue
I could use to attach the lenses to the inside or outside of a normal mask,
and if it would indeed be safe to do so.

Unless you have a depth and time backup, if your computer craps out the dive is
 over.  Air-intergrated, wrist mount or console mount, IT'S PERSONAL PREFERENCE
!  Unless you are about out of air, loosing the computer is not crucial, you
 just abort the dive.  If you lose a standard (non air-integrated) computer,
 you have air pressure reading, but you lose your time and max depth and if its
a repeatative dive you lose built up nitrogen levels, which can abort the rest
of the days diving.  IMO, if you lose any computer you abort the dive, unless
you have backups (not your buddy's, your own), if it's an air-integrated
computer you have another worry if you were low on air when the computer died,
but since you are aborting anyway, what's the big deal.  I like my
air-integrated computer for the simple fact that it tells me how long (in
minutes) my air will last at  this depth and therefore I don't have to figure
out myself how low that 2500psi (500psi for safety) will last.

This effect is quite noticable on non-lithium batteries, and most
battery mfr's will note this effect in their fine print.  Lithium
batteries are notably resistant to this effect.

I've had batteries which reported LO LO on the bottom report no error
after sitting in the sun on board for a while.  What one learns to do
is make sure that the computers have a valid voltage reading, and to
adjust mentally for the environmental conditions.  For example, I'll
dive a slightly marginal battery in the Caribbean, but I'd change it
immediately in Carmel, CA.

The bottom line is that you still need a consistent voltmeter.

I also now use a mask with off-the-shelf lenses.  Years ago, I would wear
glasses under a plain mask.  Even with 'defrogger' the glasses generally
fogged up, so I'd be a bit hesitant about this solution.

I am travelling to Greece, Turkey and Israel in the near future and would like
some information about diving in these areas.  I am certified with a PADI Open
Water Level 1 and I would probably still consider myself as a beginner (only
done several dives since certified).  I will be in these areas for about 5
months so I will have plenty of time to dive although the budget will limit
such activities as I have none of my own equipment.

If anyone could provide me with information about what to see in the
Mediterranean and Red Seas (I plan going down the Sinai coast from Eilat where I
believe there is some spectacular diving).  Also info on recommended dive shops
and trip organisers would be greatly appreciated.

All this discussion of strange behavior by computers when the battery is low
really concerns me. At what voltage level do the readings become erroneous?

If it is possible for the portions of the hardware and software that process
depth info to be screwed up, this leaves open the possibility that things like
the nitrogen loading values can be screwed up as well, and there wouldn't be
as obvious an indication of it as the erroneous depth readings described.
In other words, there could be silent errors that are not manifestly obvious,
but could present a serious safety hazard as a result.

Further, at what point (i.e. voltage level) do these errors start to show
up? Is there any way to determine when the computer is about to fail?

Despite all of the problems the Delphi has had over the years, and the
additional problems that Orca's demise created, this discussion has made
me extremely thankful that I have a Delphi, as it has a very reliable and
inforamtive battery status indication mechanism. This discussion has elevated
such a feature to the mandatory category on my list.

As such, when considering purchasing a dive computer I would recommend the
Phoenix (Delphi follow-on); I'd hate to have a DataMax and have it decide
in the middle of my ten day vacation to Truk that it was going to crap out
due to a low battery, and that I couldn't even replace the battery if
I wanted.

The Delphi and the Phoenix give ample, clear warning that the battery is
running out, giving plenty of time to change it. Given the price of a
vacation to tropical destinations, the few hundred $$ saved by purchasing
a DataMax Sport over a Phoenix begin to seem trivial.

I use an old sock for this. It may not look as cool (depends on the sock
I guess) but its cheap and has worked well for me. You also don't feel 
as bad about losing them and they seem to be an endless supply of them. :-(
Just pull the sock over your console all the way to the toe (if there
is one! B-) ) and then double it back over. I always try to keep my
regulator separate from the rest of my gear and carry it on when flying.
Too expensive and important to lose or get destroyed. Besides you can
usually get by with crappy stuff for everything else if you have to.
But your life depends on the regulator working. Same applies to tanks.
Although in traveling quality can sometimes be a concern.

On a recent dive trip, I heard a story about an instructor using the
Datamax while training four students on a "deep dive" course.  This
was out of El Mar, the largest dive shop in Arizona, and supposedly
happened quite recently. 

The dive plan was set for 100 feet (square profile dive).  After going
down, one of the students noticed that his gauge showed 130 ft, but the
instructor hushed him up.  They completed the dive (my guess is staying at
the maximum time for 100 ft), and did a direct return to the surface. 
Result: all four students, and the instructor, got bent.  

My buddy and I have different brands of computers, partially for this
reason, and always compare depth readings at least once during a dive. 
After hearing this story, we're going to make this a rule.
