That isn't necassarily true. If the student was using the new revision of the openwater course then there isn't a separate book, the knowledge reviews aren't different and there are additional quizzes and exam questions that you have to do if learning the RDP not the computer. In addition, while the online simulator is highly recommended, I don't see anything in the standards requiring its use.

Since the OP clearly said there was no computer instruction in the course, I am willing to bet that the brand new materials with complete computer instruction were not used.
 
Looks like the OP hasn't returned to SB since posting this. It would be interesting to see what he makes of all the debate. My guess would be that he decides, no, he's not "nuts" for wanting to learn tables, he's going to find resources to help teach him, and that's that. It never fails to amaze me how even the simplest questions turn into heated debates.

This is the reason I didn't want to get into a debate about this. People who have been long-time lurkers who finally dare to make their first post often "write off" scubaboard when people like T.C. use their genuine questions as a podium for the pumping negativity and the beating of dead horses into threads.

We've lost *so* many people over the years because of this.... I feel bad for allowing myself to get sucked into it. yet again.

That was my first impression as well. It seemed like a standards violation. However, I didn't want to respond immediately to him that his instructor was violating standards because (a) he was a first-time poster (b) the truth is usually more nuanced and (c) his question was about whether or not he could benefit from learning tables.

I agree with you Rob, sometimes it is just better to stay away.

Sure, there can be a benefit to understanding how to manipulate a table, just as there is to understand what a computer is telling you.

Lynne made the most rational comment regarding "tables vs. computers" I've yet seen.

I will give two real examples. For the first, knowing how to use a table will help if your computer craps out after. For the second, if the computer crapped, the tables would tell you you'd be well into a decompression situation.

For what it's worth, the first "square profile" is from a Manta dive off the Big Island.

I propose a dead-horse forum. In that forum, the standard debate would be fairly summarized and posted as a sticky. When someone starts beating a dead horse, a moderator could split off that part of the thread to the appropriate thread in the dead-horse forum. That way, posters would not be censored, and they could have their say. If they felt that the summary in the sticky omitted an argument or did not present it fairly, or if they just wanted to have their say, they could do so freely and without reservation. It would be on topic. Although many issues have been discussed over and over again, there is a constant stream of new posters and some, quite reasonably, feel they should be able to get their two cents' worth in. After all, if 250 people have already beaten the dead horse, why can't they have a turn?

If I were to post a question about ice diving in the Belize forum, I hope the moderators would move it to a more appropriate forum. And I do see that threads are often moved to, or split off to, what a moderator feels is a more appropriate forum. That is one of the functions of a moderator, isn't it? To move threads that are started in the wrong forum or that veer into another forum's province?

Of course, I wouldn't call the dead-horse forum the "dead-horse forum," for that implies that the topic a poster wants to discuss is not worth discussing and is therefore condescending. I would call it something like "Common Controversies." Perhaps the first thread in the Common-Controversies forum could be "Proposals for new forums." :shocked2:
 
Because a lot of shops are pushing dive computers and not including the gauge with the standard equipment. No one is dropping it. They are substituting.

If they are substituting...the definition of that sort of means they are dropping it. They are dropping it in favor of a computer.

And if you look closely at those consoles you might notice they have dive computers in place of depth gauges.

I will pay closer attention to the rec diver equipment I see in the future. Either way, my opinion is that, without the level of training you have, qualifying you to decide if you need a depth gauge or not, it is silly to dive without one.

While there are valid reasons for bayonet training, even the Army has limited time for training.
Ah...The "Army Times". The National Equirer of the Army. It's a tabloid, nothing more. Their stories almost never come true. Those of us serving tend to moan when we see something good in it; because it's like the kiss of death for something we wanted to see.

Believe me; we teach bayonets. Once Hertling (the same silly goofball behind all the stupid PT revamping) left, they came back.

If only an hour is spent teaching the tables, then the student won't master them, and it's the waste of an hour of teaching time. Using the tables is not rocket science, but using them is certainly not intuitive. It requires practice, practice, and more practice to become proficient.
Then take the time that is required to teach them. Most divers can learn this tool on their own, with the instruction booklet and practice problems. Thus, only an hour or so will do it in the actual class.

My only point in chiming in was to emphasize that while it's great to learn tables, it is not NECESSARY. To me, "necessary" does not mean necessary to avoid having to sit out 12 hours or whatever. To me, necessary means necessary in order to enjoy the kind of relaxed vacation diving that many many of us out there do.
Ah, applying your own definition of how to enjoy a vacation", I see. Your definition of "enjoying a vacation" is not the same as others. Your arguement fails on this point; because you are looking at it solely from your point of view.

Judging from SB posts, some newly minted divers can't wait to spend their dollars.

Some want to buy gear, but know that there are other priorities first. Like their kids eating.

On resort and liveaboard dives, you ask the DM how deep and long the next three dives today will be, and he's not even sure yet of what site we're going to visit FIRST.
Then he should know the average, or at least what the the profile of that first dive should be like.

And just what WAS the depth of that last dive?

That's what your analog gauge is for. They have this handy needle that records this info for you.

It was likely VERY multi-level, complicating the use of tables.

No, not really. Compute it as a square profile.


While few of us advocate blindly following the DM, who in their right mind is going to go out of their way to piss off the DM whom we are spending a week with?

Any DM trying to plan my dive for me will get the warning that I will plan my own profile, then the warning that continuing to try to control my profile will adversely affect his tip. The confirmation of this is usually accompanied with a finger. I will not tolerate unsafe planning.

To the extent the diver deems it safe, we tend to go with the flow, not against it.

This is why we get such entertaining reads in the "Lessons for Life", the DAN magazine, and the Accidents and Incidents forum. People think that they can just go with it, and become underwater sheep to be lead around. "Trust me, I'm a DiveMaster...".

Makes me more worried than a new Lieutenant saying, “I think we should…”.



one considers that a backup computer that should last for years can be purchased for a fraction of the cost of just one vacation….But for those divers who can't afford an extra $250 computer, I suggest being careful about booking a $3,000 week-long liveaboard or trip to Cozumel…I would think that divers who dive only once or twice a year are the ones who would not be overly concerned about spending money on their vacation.
Again, not everyone has money to blow like you seem to. It would be nice to see you not interjecting your fiscal priorities onto other divers. Those divers going once or twice a year are probably the most likely to be concerned about spending money on dive gear. They’re probably vacationing only once because they can can’t afford to go more often.

When the difference between going on a vacation and not is a few hundred dollars, the idea of spending the equivalent of the next two weeks’ worth of groceries on a backup computer is hard to justify. So that leaves a diver without a backup plan, unless they were taught tables.


T.C. has added his own extra "flavour" to this thread by also suggesting that if a student does not understand tables and/or is not able to remember it permanently after the class that there must be someone to blame. This is a twist that we don't see all the time.
I know…you just want to let people off the hook. After all, having a quality instructor or skilled diver isn’t as important as avoiding a tragedy like…hurting someone’s feelings. Heaven forbid you actually assign blame.

He suggested that I must be an inferior instructor because I don't agree with him or that my observations that people can forget things means that those people are not taking "personal responsibility".
Liar. I said you would be an inferior instructor if you didn’t teach something, or taught it poorly. I did not say it was for disagreeing with me.

If you as an instructor do not teach a student something, or teach them poorly, you are to blame. Likewise, if someone is properly taught, and does not maintain their skills, they are to blame.

You can’t dodge responsibility by saying, “Oh, I forgot…”. This applies in every profession in the world; I submit a medical Doctor for example. They devote a considerable amount of time staying current in their profession and maintaining their knowledge. The same applies for divers. You, the diver are responsible for ensuring your skills stay sharp.

This edgy manner of debate makes for good "gladiator sport" but is so utterly devoid of objectivity that I refused to respond to it. Perhaps someone else would like to get into the ring about this.....
People who have been long-time lurkers who finally dare to make their first post often "write off" scubaboard when people like T.C. use their genuine questions as a podium for the pumping negativity and the beating of dead horses into threads.

Right. So you just lie about what I said, and then take personal swipes at me. Good job, moderator.

Second; point out anything I said to make him 'write off' the board. I encouraged him to get the training, and have repeatedly congratulated him on wanting to get it.

It was argued that the diver is *less* skilled -- i.e. less capable -- as a diver if they do not understand tables. This point could do with more debate. In my mind the *skill* of a diver has to do with whether or not the are able to plan and execute a given dive. The tools they use to do that are of secondary importance in my mind.

What of a cheap computer that does not have the ability to plan dives? What do you recommend to a diver on vacation who rents a computer, only to find that all the computers for rent do not have the capability to plan dives? How should the diver plan their next dive then? Without the ability to use the single skill they were taught, computer dive planning, they are now sorely lacking in your own measure of a diver’s skill, whereas a diver with the ability to plan with his tables has a definite advantage.

T.C. has repeatedly argued that the tools the diver uses *do* define whether or not they are skilled as divers. I tried arguing that a modern mathematician may be skilled without knowing how an abacus works and a modern diver may be skilled without knowing how a J-valve works. Likewise, I think I modern sailor may be "skilled" without being able to navigate with a sextant.
So a sailor with the ability to navigate by sextant is not better than one, of otherwise equal skill, who cannot? A mathematician with the ability to use an abacus does not have an edge, however very, very slight, over an equally skilled colleague? My point is that just because a certain skill does not have a current application, or one that you can foresee, does not mean that skill is worthless or not worth teaching.

Given two divers of otherwise equal ability and skill, one knowing tables has an edge, however slight, over the one who does not. This point is beyond dispute, it does not matter if there are better tools out there. It is one more tool in the toolbox, one that is not hard to teach.

I see no reason to drop it from instruction, and the OP is to be commended for wishing to learn it.

I propose that there be a new forum called "The Ring".
In the Ring you can duke it out with whomever you need to for as long as you want without the thread getting shut down or a poster getting banned.
Threads that go down to the grappling level would be moved to the ring, or posts that call people out and look like they are deteriorating get moved to the ring.
Kind of like in high school where two guys have it out for each other and so they put the gloves on and give it a shot in the gym boxing ring. They come out best friends once the dust settles.
The only thing you couldn't do is use 4 letter words but that's a given on the internet with the spam bots and all.

Ah, applying your own definition of how to enjoy a vacation", I see. Your definition of "enjoying a vacation" is not the same as others. Your arguement fails on this point; because you are looking at it solely from your point of view. . . .

YES, I AM APPLYING MY OWN DEFINITION and YES, IT IS MY OWN POINT OF VIEW (this is a forum to express points of view, is it not?), as I think I made clear elsewhere in my reply. As I said, the OP may or may not do the same kind of relaxed vacation diving as I do, and I'm not "arguing" he do or not do anything! I believe I said repeatedly that I'm not advocating that he NOT learn to use tables. My only intent was to note the OPTION of not bothering with tables if he does the kind of vacation diving that many of us do, where we view a computer failure as not more than a minor inconvenience. He may or may not fall into that "definition"--I never implied knowledge that he does. We don't know what kind of diving the OP intends to do, or how he feels about sitting out the rest of the day if he experiences computer failure, or how he feels about the idea of a backup computer so he wouldn't have to sit it out, since he hasn't returned to the thread. And as I also said, as a new diver he probably doesn't know what kind of diving he intends to do. What I did was note options.

Again, it's no wonder that with argumentative trolling posts like yours on SB so few new posters return here. You do your best to interpret posts in a way that conflicts with your opinions. What a turnoff to have to preface every statement with an explicit caveat of "I'm not telling the OP what to do or implying this necessarily fits the OP's situation, but the OP might consider ...."

By applying only your own definition, and discarding the validity of the opinions of other people, you are giving him deficient advice. You are telling him, in essence, that if his computer fails, he should just hang up your fins for the day, drink a beer, and watch all your friends have fun; because that’s what you do.

You are telling people that if they don’t spend money to have a backup computer, it’s not necessary to learn tables as a backup, and they should just give up for the day. The point of this forum is to help people, especially new divers, and telling people with only one computer that it’s not necessary to have a backup plan unless they shell out money they may not have for another computer, is not helping them.

I believe I said repeatedly that I'm not advocating that he NOT learn to use tables
No, your post, strongly emphasizing that it is not necessary to learn tables, does advocate for not learning it. You said that in your opinion, “…it is not NECESSARY.” Emphasis yours. How does that not advocate against learning tables?

Again, it's no wonder that with argumentative trolling posts like yours on SB so few new posters return here. You do your best to interpret posts in a way that conflicts with your opinions. What a turnoff..

You have no evidence whatsoever that our debate “drove him off”. For all we know, you telling him that his desire to learn more is not necessary drove him off. Or, like he himself said, he’s a lurker, and doesn’t post much. But good job in trying to malign me by endeavoring to make the asinine correlation between you getting upset at me, and him not returning.

But, hey, thanks for the insults. Nothing I have said could be “trolling”. I’m doing the same thing you are, expressing my point of view. Maybe next time you post you can learn to control your emotions when people have the audacity to disagree with you.

Yep, if my computer dies on me, I am done diving until I can replace it with a new one, a rented one, or a borrowed one. Since my standard kit excludes an independent depth gauge, a dive watch, and a set of tables, knowing the tables does me zero good in this instance.

From the cost aspect...an inexpensive usable depth gauge + a cheap water proof watch will run you about $150. You could go cheaper with a ~$24.99 watch, but would you really want to? An inexpensive dive computer runs about $170. For the added $20, might as well just get the back-up computer instead of a cheap set-up just to use the tables in the event of a computer failure.
