Sharing a Dive Computer

[me_diver]

They are not saying that. They are saying not to share. And, funny timing on this, PADI just changed their course to be computer only. Dive tables are out now.

I'm new here, and not trying to stir up controversy, but I'm taking a PADI-OW course as we speak, and we are required to learn the dive tables, and plan a dive with them, only. ?

me-diver, Welcome to Scubaboard, where everyone has an opinion or comment and MOST of the time they are valid, correct, worthy, or at least merit consideration as points to ponder.

Herk_Man is not completely correct (see my previous post in this thread). Many PADI instructors will continue to teach tables (some w/ and some w/o computers) because they are the basis of understanding the theory of depth/pressure vs time, no decompression limits, and the impact of surface intervals. Understanding the basic tables will allow you to recognize the utility of computers as well as give you a simple background for further training in gas management as well as technical deco theory & diving and should you pursue that type of diving. If you have questions or want additional training on computers, consult your instructor.

This is also an acceptable means of promoting dive safety as opposed to justifying the possibility of increased risk by assuming the dive profile will fall within arbitrarily "safe" parameters for divers with unverified skill sets.

Needs citation.

What increased risk? Please provide studies and/or statistics to back up your claims. You keep frothing at the mouth here about the fact that they will surely die, and you have yet to provide any inkling of evidence that this is the case. I have shown the primary premise as well as a few tertiary premises to be false, yet you have provided naught but vitriol condemning me as promoting the deaths of the innocent. Please provide evidence that this is so. You have not even provided the training standards for your agency in support of what you contend must be true.

This is major shenanigans.

Sorry Herk_Man, not true. PADI did just add to the OW Course as OPTIONAL the "How to Use and Choose Dive Computers" Crew-Pak. The instructor may still choose to issue/use crew-paks that include RDP tables only, or e-RDPs only, or this computer version.

If you are not a PADI Instructor, have not attented a recent instructor's update, or kept up with the updates disseminated on the PADI Pro site, then maybe refraining from making blanket statements until you have verified the information, will make your comments more credible.

Wow girl, put those fangs away. My information came straight from the mouth of the owner of my LDS. Maybe you're right that my information wasn't precise, dunno for sure. Will check. But I'm pretty sure I didn't deserve your unbelievably rude attention. Go find a ledge to get stuck under.

The increased risk of incident due to not managing your own environmental situations such as time, depth and SIT that divers tend to rely on to plan and execute their dives. Statistics and data are wide spread, I suggest you turn to NAUI as you purport to be an instructor for some general guidelines to dive safety through education.

Not once did I say anyone would die, the only frothing is coming from you as you adamantly defend what the majority here and dive community in general know to be a bad idea all the while trying to make me out as some sort of crazed dive nazi obstructionist with my head buried in the sand.

I'm certain your clown like antics have bolstered the opinions of several folks on here about the quality of advise you offer. I'm sure dive organizations around the world will be clamoring for leadership such as yours. Good luck with that.


Feel free to go ahead and get the last word,I'm done with it and I'm sure we're all on pins and needles.

If the instructor has not purchase the update material to teach computer for the class he has to still teach tables.

Once you get your own computer or rent one you can use that for planing your dive instead of tables.

simpley put, just don't use a computer for more than 1 person its the safest way of assuring that no one gets injuried etc....

One little comment...
When you go diving in exotic areas, and you are a simple tourist without your own gear, you go with a group, and the club provide the equipment.
There are still plenty of dive clubs where you get to have only an SPG, not even a depth gauge.
The DM will be the one controlling the dive with his own computer, and he advises you to stay always at his level or above... which of course few people do exactly.
So then a lot of people (4 to 5 per DM) would share one computer ...

Most of the time, for 1 dive above 60ft, and under an hour, it is not really a problem (while you could exceed or get close to the tables, and have the ascent rate issue, but you are suppose to know how to deal with this one)

But for 2 dives, when little more at the limit (like in place where people go deeper to see big sharks), it starts to be very dangerous. In warm water, you can stay much longer u/w.
So I really think these clubs only supplying an SPG are playing with the limits, as they indeed do allow the 'sharing computer' idea.

So if I only have 1 piece of gear to bring during dive trip, where I know I'll do 2 dives, it is the DC !

I guess I misspoke - we are learning *BOTH* ways but first, one has to understand the tables and what it means, and how to plan a dive that way. What happens if your computer dies/malfunctions? Don't you still want to know the times you can stay at certain depths? I mean, we have a chartplotter on our boat, but we still know how to use paper charts, and have them available, should it malfunction. I assume people dove before computers were invented and were commonplace.

I agree, if you are only relying on a computer, you should have your own.

You abort the dive and sit out for 24hrs before your next dive.
